The Best Marine Varnishes

Written by J. Harvey / Fact checked by S. Numbers

Let’s face it, we don’t give as much credit to the almost perfect combination of boats and varnishes. After all, vessels aren’t exactly cheap. They aren’t immune to deterioration as well. If there’s one solid way for you to preserve the life of your investment and even take her beauty up a notch, wouldn’t you seize it?

For my part, I can wholeheartedly say that these varnishes are great investments, especially if we’re talking about the best marine varnish. These concoctions go beyond their practical benefits, lending anything made of wood with a nice finish that only unlocks and magnifies their natural exquisiteness.

I can say as much for the products I’ve featured here. They have given me noteworthy, if not outstanding, results that make the others I’ve tried in my more than ten years of boating and fishing pale in comparison.

• Great finish
• Easy to use
• Great value for money

• Superb satin finish
• High gloss protection
• Very versatile varnish

• Easy to apply
• Excellent UV protection

If I’m going for all-around reliability and protection from sun and moisture damage, I’d choose this varnish in a heartbeat.

This is my go-to varnish for anything wood found in my sailboat. Whether it’s furniture or railing or sometimes even the bow, I often get the kind of maintainability I want every time I use this. The finish is no less attractive and only gets glittery over time in a number of my past applications.

Thinned up to around 30%, it dries quickly enough to apply multiple coats in a day. Sometimes I go for as low as 20%, down to even 5%. It’s because thinning too much does tend to backfire and lead to the varnish taking a long time to dry. It’s easy to use with everything considered.

If you want the best results, I’ve found that using a fresh foam brush with every coat would result in optimal smoothness. It may seem like a waste, buying multiple brushes, but the results are unrivaled, to say the least. I’ve had applications that lasted for a good 3 years before I needed to refinish them.

• Excellent UV and water protection
• More affordable but with high-end results
• Low shelf life

This varnish smoothly combines ease of use, beautiful finishes, and above-average durability. The winning formula for successful marine finishes for wood, in short.

This varnish is versatile in that it leaves plenty of routes open for you to take. For one, I like that they give you plenty of freedom when choosing the shine you want. It’s also available in different sizes, so I always get to buy only the proportions I deem fit for a specific project.

I have to be partial to the satin finish, though, since it delivers the exquisite luster I like to see in my indoor boat furniture and fixtures like railings. However, I always make sure to apply a high-gloss varnish if I’m working on anything that has to be exposed to the sun for long hours. That being said, I like that this product gives you both satin and gloss options.

I make sure to apply the high-gloss varnish as a topcoat, and I’ve gotten excellent results, mostly 1 to 2 years of unblemished finishes, with this practice. Sometimes, it’s shorter than that, especially on wooden areas that are more exposed to the elements. Yet, it’s protection you normally expect and can get from high-gloss varnish. In addition, it’s a varnish that’s also noticeably on the thin side, so I kind of get that it wears away faster than thicker varieties.

• Uncomplicated to apply
• Has multiple sheen and size options
• Not as durable as others

Another safe option, Epifanes marine spar varnish is anything but average with its status as a crowd favorite. Expect superior finish and durability if you choose this.

This varnish easily earns a spot here, considering its unchanging and undeniably positive reputation among boaters. Simply put, it’s hard to fault because of the wonderful results it can bring. The shiny, attractive gloss that has the Epifanes trademark is rarely surpassed by other marine-grade varnishes in my opinion.

What’s equally neat is that it’s not difficult to apply. You don’t really need to sand it with every coat, unlike the majority of other brands out there, but I still suggest you do it, especially in the later coatings. I recommend using marine spirits as a thinner with a 2:1 ratio, and take the time to pour it through a strainer to guarantee a smooth finish. At best, you’ll have to set 5 to 7 days of gradual coating to get the kind of attractive finish you want; and I mean capital-A attractive.

As in other great exterior varnishes, this product is an example to follow when imparting UV protection. At least, that’s what I think is primarily responsible for the excellent finish and the overall durability. I use this as much on my sailboat’s wood portions above the waterline and furniture as well as furnishings in my home, and the finish often lasts for 2 years on average.

• Amazing shine and finish
• Takes a while to dry
• Short shelf life

McCloskey’s Man O’War spar varnish is durable, to an almost no-brainer degree. It’s what I buy if I want to get the best out of what spar varnish offers to the average boater.

Despite its relatively hard finish, spar varnish tends to wear out faster than urethane. It’s a natural thing, so I won’t bother to list it as a con. You can’t mimic the deep amber tint, caramelization, and versatility of good old spar varnish, and this brand delivers no less than that trio of perks.

If I’m going to name a worthy brand representative of spar varnishes, I’d promptly pick this one. It adheres excellently to any kind of wood, so I generously slather any wooden fixture in my boat with this once I get a hold of a bottle.

While it’s easy to use, you’d better be prepared to invest time working with this varnish. I use mineral spirits for thinning, and I make sure to apply thin coats, starting from the middle, using a mini roller and a brush, mohair and ox hair respectively. I sand in between coats, and overall it takes time since it dries slowly.

The durability stems a lot from the outstanding UV protection. My sailboat’s wooden bow that has this finish has been battered by rain a good number of times already, and it’s still holding up after a year since the initial application. Since it’s effortless to apply, I just sand and recoat every once in a while.

• Outstanding UV protection
• Adheres to most types of wood
• Classic, eye-catching spar varnish finish
• Slow-drying
• Limited availability

TotalBoat is a household name in the marine industry as far as paints and varnishes go. This is the brand’s best offering if we’re going to consider fundamental factors like durability, shine, and value for money.

I need to stress outright that this varnish is extra thick, almost honey-like. If you don’t thin it out to at least 50%, you’ll only end up grappling with it to less than desirable results. It’s not exactly beginner-friendly with that considered, but it does pay off since you get optimal protection and the kind of shine any boat owner would be proud of.

Speaking of the finish, it begins to shine through once you hit the one-year mark. At least, that’s what I get from most of the vessels and furniture I apply it to. I can say that it’s smooth sailing once you take the time to know the right consistency.

I often use a roller and apply 5 coats then do a recoat after 2 hours in a whole day. Ideally, the last two coats should only be thinned by about 10% only. It might get tricky applying it then but, trust me, you’ll get the hang of it.

I get the results I want within a day or two — or more at times during less than optimal humidities and temperatures. Even so, that’s obviously quicker than handling traditional varnish, which takes weeks to settle. I do acknowledge the thinner’s role in helping with the drying time.

• Excellent shine and finish
• Proven durability
• Becomes easy to use with practice
• Quick-drying

If we’re talking about top-of-the-line, marine-grade durability, this one deserves to be called the best marine wood finish.

This is my favorite to use on teak because of its proven waterproof capabilities and the fact that its satin finish has just the right amount of sheen, for me, at least. It brings out the beauty of the teak and almost any wood I apply it to, for that matter, and this is coming from someone who has tried numerous marine-grade varnish before. I’ve had furniture that managed to maintain its finish for an impressive 5 years with the help of this varnish.

It’s a bit of a challenge to apply. It actually flows well enough as it is, and I rarely have to thin it with every application. However, you have to make sure that you apply it evenly with every coat and oftentimes as quickly as possible. Once I get patchy and bubbly results, that’s the only time I thin it, and I sand after the first coat, totaling up to 3 coats on average. It will dry more slowly if I thin it, though.

• Excellent durability
• Nice satin finish
• Flows smoothly without thinning
• Brings out the beauty of the wood extremely well
• Fairly cost-effective
• Not beginner-friendly

Though not marine-grade, Minwax has proven to be just as durable as many products with that label. It’s very easy to use and delivers just the right amount of shine.

I often use this on my sailboat’s furniture, and if left with no other options, even the wooden exterior of the hull and bow. It goes well with canoes, but I only tend to apply it on the ribs, rudder, and planking. While not marine-grade, it’s great for outdoor furniture, and, to me, that’s always a good sign of heavy-duty UV protection.

If I want to reinforce the protection, I only need to apply more layers, 4 coats at most but not less than 2. I’ve only used it on oak-made fixtures, though, and I get the longevity and finish I want with that kind of simple setup. The varnish lasts up to 1 to 2 years before recoating becomes necessary, with minor peeling only appearing after a year based on my experience.

I like that they give you plenty of options with regards to sheen and container sizes. I prefer satin for my interior furniture. I once made the mistake of not mixing it well and got a result that’s almost similar to high gloss. To avoid this, you need to make sure you mix it for a good 5 minutes and scrape the sides and bottoms of the can as you do so. This guarantees the soft shine you’re aiming for.

• Plenty of sheen and size options
• Decent durability
• Dries quickly
• Not exactly marine-grade

This varnish earns my thumbs up with the kind of inimitable finish it can deliver and its relatively easy application.

This has since become my favorite varnish on teak fixtures when I tried it out 2 years ago. This is because of the immense difference it makes in the way it lends my pulpit or anything made of teak with a sophisticated, good-as-new finish. It’s not overly glossy, which I attribute to the “natural teak” claim, and only darkens the wood a tad so it will still maintain its natural hues.

I’m glad it didn’t cause any yellowing, and after my second application, I can still say the same. It has a runny consistency that merits forgoing thinning on the first coat. I like to use a brush when applying it to have better control over coverage, which is great enough as it is, and all I can say is that I’ll apply this to my boat’s bow and rails the moment they start showing signs of wear.

Nonetheless, it would be pushing it to say that it’s as durable as the other varnishes here. It only took a year before my bow showed signs of peels and cracks. However, after I applied a single maintenance coat on the entire thing, I found that it limited or delayed the damage since I’ve yet to see signs again after doing a recoating. That being said, I suggest applying a fresh layer at least once a year to make the most out of this marine varnish for boats.

• Outstanding finish
• No sanding and thinning required in most cases
• Good coverage
• Minimal darkening
• Well worth the money
• A bit pricey
• Not durable

Budget-friendly, reliable, and just as good as other solid brands, this McCluskey varnish is a must for anyone choosing to go for value for money all the way.

The fact that this varnish can give you outstanding satin finishes and superb durability without going overboard in cost should give you a ready hint why a lot of boaters are shifting to this product. When I say superb durability, I mean thick coatings that you’ll be confident will last for years.

In my case, the minimum is 3 years on all my wood projects, boat bows, railings, and furniture included. You may start seeing peels and scratches here and there, as evidenced by the 7-year-old canoe that I refurbished 3 years ago. But, to me, it’s still none the worse for wear and nothing a minor recoating job won’t remedy.

The finish is not unlike the ones I get from the other varnishes mentioned here. It accentuates the natural color and look of the wood, and I’m saying this for redwood, teak, and light oak, which are the types I’ve applied it to. It dries in a day like most spar varnishes and typically doesn’t need to be thinned, though sanding is ideal per coat.

Incidentally, I need to underline the fact that this varnish is one of the few that doesn’t skin over in the can after you’ve stored what’s left of it. At least, that’s what I can say for most of the cans I’ve purchased and stored, with about a third of the can full in a year.

• Works well for most types of wood
• Superior durability
• Doesn’t skin like other varnishes
• More reasonably priced than other brands

This rarely figures in marine varnish review posts, and that’s unfortunate considering it’s another top-quality marine varnish that doesn’t yellow, imparts a glossy and thick appearance, and superb UV protection.

Usually, I use this as a general-purpose varnish for the teak and cedar parts and fixtures of my one and only yacht. It gives a deep-colored, thick, glossy, grainy, and smooth finish that I can’t get enough of. It doesn’t yellow at all, probably because of the UV additive used, at least, partly. Anyway, this is one positive quality I always like from any alkyd varnish that is done right.

I prefer to spray this one, following the 20% thinning guideline. Spraying shortens the time for full coverage. I sand lightly between coats using 220-grit sandpaper, and by and large, I only need 3 to 4 coats to get the beautiful finish I described above. It takes almost a whole day to dry, but I don’t mind since I get quality results.

As for durability, I can safely say it’s UV stable. I often leave a couple of chairs and tables out on the deck if the weather’s great, oftentimes, for an entire day. Besides a few scratches in some parts, which aren’t UV-related, they haven’t peeled yet and have maintained their shininess after 2 years since application. I can say the same for the yacht’s teak pulpit.

• Doesn’t yellow
• Superb UV protection
• Proven gloss retention

To me, this is the best boat varnish if we’re only considering durability. It also earns a ready checkmark in protection and attractive finish, making it nothing short of tough to beat.

As far as durability is concerned, the longest that I’ve seen this last without undergoing any kind of major peeling or cracking is close to 3 and a half years. It was on my favorite canoe, which I use fairly regularly for freshwater fishing. 3 years is the maximum for any exterior wood varnish for me, and without a doubt, many boaters would say the same.

I attribute most of the longevity to the excellent water and UV protection. My canoe has borne the brunt of rain and water splashes over the years. I can say the same when I expose it to extensive sunlight exposure when I go fishing in Lake Erie. Top-tier durability in my book.

I sometimes use a thinner with this varnish, but I’ve found that you don’t really need to thin it if you use an HVLP spray gun. Sure, it takes a while to dry and you have to be extra careful, but I’ll take that any day if I get to enjoy these perks and results consistently.

• Outstanding durability
• Relatively attractive finish
• Easy to apply with a sprayer
• Comes in gloss and satin varieties
• Dries slowly without a thinner

A true gem of a find, Duralux exceeded my expectations with its durability and versatility.

In almost any kind of marine varnish for exterior doors, durability and protection immediately go well together. This spar varnish proves it doesn’t belong on the back burner by delivering both. One of my canoes that I applied this on is still going strong for more than a year, and that’s a quality not a lot of products can boast of.

I’ve had varnish that didn’t take more than a month to start peeling and cracking. That’s after a fresh application, mind you, and, yes, I follow brand recommendations to a tee if I haven’t discovered a better way to apply it. This varnish has kept my other canoes shiny every time so I deemed it deserves the spotlight.

Moreover, it doesn’t yellow over time, unlike some clear varnish I’ve used before. You may argue that there’s a lot of variables when it comes to varnish yellowing, like sanding and possible chemicals it can react to. I’m not sure whether this is spar polyurethane, but I’m betting it is since that’s the only type of varnish I’ve used that doesn’t give me the yellowing effect even with minimal to no sanding.

• Satisfactory finish
• Uncomplicated application
• Doesn’t yellow over time
• Doesn’t dry quickly

Old Masters’s varnish shouldn’t be overlooked for its conveniences and quality that only a few top-tier varnish brands can bravely claim they can deliver every time.

This is among the lesser-known spar varnishes that don’t yellow even after a long time has passed. The canoe that I refurbished 3 years ago would prove as much, as it’s still holding up well, surprisingly if I might add. To be honest, this was a second option when I bought it as I didn’t have TotalBoat and McCluskey varnishes available back when I did the finishing job.

I was pleasantly surprised by how things turned out. I followed the instructions and stirred it well. It’s just the right kind of thick, to the point that I don’t have to thin it when applying with a brush or roller. I do have to thoroughly sand and clean the surface first, and it evens out nicely with every coating.

It dries quickly enough for me to apply a second coat in a single day, making me think it’s an exception among oil-based spar varnishes. At best, I give an allowance of 8 to 10 hours before brushing the next coat. Obviously, that’s a time-saving perk I’ll take any day.

It doesn’t produce a yellowing effect, even when applied to parts of my canoe that are regularly exposed to heat, sunlight, and the elements. That’s noteworthy considering it’s a clear varnish. I even have to say that the slightly weathered look it has gotten lends it a charm that most boaters would appreciate.

• Easy application
• Decent durability and finish
• Doesn’t yellow with age
• Limited to small pint-sized cans

Based on my experience, there are many “safe” marine varnish options out there. This only means you’re likely to not run out of beginner-friendly brands and can guarantee high-quality results at the same time. Whether it’s high-gloss or satin, all spar varnishes are easy to apply over new wood or previously coated surfaces. Marine varnish is also not partial to any type of wood and can accommodate those commonly found aboard or form part of a vessel, like teak, redwood, oak, etc.

However, that doesn’t completely discount the need to pay attention to certain factors when making your decision. These are usually the ones I make a note of when planning to start a varnishing job.

• Durability – I’ve found that marine-grade polyurethane is hard to equal when it comes to finishes that are guaranteed to last. Most spar varnishes pale in comparison to their urethane counterparts in this regard because polyurethane tends to last for a minimum of 3 years before re-coats are needed, based on my experience. This is why they’re great options as a marine varnish for outdoor furniture.

For spar varnishes, I’ve had finishes that only lasted a year or even less. At best, these two offer equally potent UV protection, waterproof benefits, and even resistance to scratching.

• Drying Time – Are you working with a severely limited timeframe and need to complete coats within a day? You may want to consider varnishes that dry faster like water-based spar urethane since these can dry in only a few hours. Most spar varnishes require a whole day of waiting to apply coats, assuming climate conditions are optimal.
• Ease of Use – To ensure you won’t end up throwing away your money, don’t ignore how easy or hard a specific varnish is typically applied.
• Shelf Life – It won’t hurt to pay attention to how long a specific can of varnish will last while in storage.
• Gloss – This is admittedly a largely subjective factor, but if you’re opting for high-gloss varnish, it’s almost always the one with the best durability. However, do you like your wood to be extra shiny? There are semi-gloss and satin finishes that are just as attractive, if not more, especially when used on anything wood that is below deck.

We also need to discuss the possibility of a varnish yellowing or darkening the wood that it is applied to. Sometimes, the darkening could be due to the UV additive or tint used; thus, making it unavoidable unless you opt for a different varnish brand altogether.

As for yellowing, there are ways to avoid it. I shall discuss it below, but sometimes, it’s due to the actual product as well, especially if they are clear, alkyd, or oil-based. It’s not an absolute thing, though, and there are products that prove to be exceptions to this rule.

You’ll hear a lot of experienced boaters recommending brands like Epifanes, TotalBoat, McCloskey, and Rust-Oleum. I agree with them because, to me, these brands can easily meet the standards of high-quality marine varnish. Each one has qualities where they serve to shine better, and the reviews I outlined above should give you a good idea about what they are.

Nonetheless, I’m not completely discounting the other brands I included here. I daresay that they’re just as good as those top-dog brands, especially in essential factors like durability and a long-lasting aesthetically appealing finish. Moreover, I find them to be valuable substitutes if any go-to brand happens to be unavailable and won’t even hesitate to pick them as the main option based on certain requirements of a finishing job.

Incidentally, you may have noticed that I didn’t include ease of cleaning when discussing these brands. That’s because most, if not all, of them are very easy to clean for me. At least, for the almost uniform smooth finishes that I get out of them.

There’s not much, really. When boaters use the term “spar varnish”, chances are, they’re also automatically referring to marine varnish. You can also see this in how brands usually label their products in online stores, like Sherwin Williams marine spar varnish or TotalBoat gleam marine spar varnish, to cite a few examples. If you’re using spar varnish, it’s almost always marine-grade.

Both terms give the ready connotation of finishes that provide heavy-duty protection against the harsh elements usually involved when boating, fishing, and cruising. You’ll find plenty of oil-based spar varnishes (i.e. tung oil, alkyd resin, etc.) that are imbued with additives that serve to accentuate the natural beauty of the wood, as well as solvents and other chemicals that promote fast drying and add UV protection.

Since certain varnishes have different components or are more natural or synthetic, it’s best to stick to the manufacturer’s instructions when applying any kind of varnish. However, we can’t deny that most projects share a few essential guidelines, such as the following:

• Preparation usually entails sanding between coats. The most ideal to use for this purpose is 180 to 220-grit sandpaper or even a Scotchbrite pad will do sometimes. Take note that some varnish products can do without sanding, especially for the initial coat. But, this would still depend on whether you’re applying it to a bare wooden surface or if it’s been previously coated before. If it’s the latter, then you’d most likely need to sand it first.
• Clean the dust that forms after sanding using a clean rag. I wipe it down further with a tack rag to ensure no dust or debris would still be present the moment I start applying coats.
• As for temperature and humidity, it’s best to apply any kind of marine varnish if the temperatures during the entire day don’t go above 80 degrees Fahrenheit. Humidity should be 50 to 60% or even slightly lower than that. I found that the smartest route to take is to be patient and wait for the right climate before going ahead with a project, especially if you know that it will take a number of days to finish.
• Thinning depends a lot on the product. If it’s too thick, it’s often necessary to do this, even if the brand doesn’t mention it in the instructions. The safest route for this is to follow a 2:1 varnish to thinner ratio. Mineral spirits are recommended.
• I also recommend taking the time to strain the varnish using a paint strainer to ensure a smooth finish. Sometimes, this can make all the difference in the world in getting the kind of finish that any boater would be proud of.
• As for applying coats, there are certain products that require you to start from the middle so that you can ensure an even coating. Others would caution about wiping too much, while many suggest, as is often the case in spar oil-based urethane, to make thin coats for every layer.
• Bristle brushes and badger-hair brushes are often the standard tool for application. But, again, there are products that are easier to apply with a spray or roller.

Most marine varnishes typically last for at least 2 years. There are brands that have a minimum of 3 years before they begin showing signs of damage. I can attest to marine varnish that keeps its shine and protection for 5 years, and I’ve highlighted the exact products that can achieve that.

Ultimately, if you keep its sun exposure to a minimum, you’re guaranteed to extend any kind of varnish’s lifespan. I’ve noticed that varnished fixtures and furniture in my yacht tend to last significantly longer than the ones that are exposed to sunlight extensively, regardless of the varnish’s UV-protective capabilities.

This is almost always the case considering this type of varnish is marine-grade. Most experts attribute this to spar varnish’s flexibility (i.e. its ability to expand and contract with the wood). However, equally many attribute it to the simple fact that spar varnish is mainly oil-based, allowing to wick away moisture with ease.

Now, do you have a good idea of what the best marine varnish brings to the table? With all things considered, the best parting advice I can give is to not hesitate to try out the options available to you. Sure, there will always be no-brainer choices, but it didn’t take long for me to find out that it pays to try out other brands because they may give your boat the kind of shine or longevity you’ve always wanted.

Best boat varnish: 7 top options for gleaming woodwork

• Drew Maglio
• October 13, 2022

Different varnishes do different jobs. Understanding their properties will help you decide what's the best boat varnish for your woodwork. Drew Maglio explains all...

Few things are as quintessential to the archetypal sailboat as gleaming, iridescent woodwork that is indicative of a recent coat with one of the best boat varnish products on the market.

Choosing a product and methodology to apply marine varnish to achieve such results is not as simple as it would seem at first glance however, and this guide aims to make the whole process easier for novice and seasoned boat-owners alike.

First things first, what exactly is boat varnish? Put simply, varnish is a chemical solution of three parts which includes a penetrating oil, resin, and solvent.

Boat varnish for exterior use, aka. “spar varnish” — aptly named because it was designed and envisioned as a flexible protective coating to protect a yacht’s wooden spar in the harsh (outdoor) marine environment — both protects and beautifies a vessel’s wood parts.

It does so by sealing the wood with a somewhat hard, yet flexible, clear protective barrier that can last up to three years of UV and element exposure in temperate climates for the most durable two-part product formulations.

These days, most high-end boat varnishes use tung oil and an alkyld or polyurethane resin. Of the two types of resin, polyurethane — either one or two part — is going to be much more durable and resistant to UV, abrasion, fuel/solvent spills, and impacts.

While a two-part product cannot be applied over a one-part product, a two-part product is going to last much longer and be far more durable. Hence for high traffic areas like cabin soles, a two-part polyurethane product cannot be beat for longevity and durability.

Boaters should be aware that the most onerous task of applying boat varnish is the surface prep, which requires removing all flaking previous coatings by sanding, washing with solvent to degrease the surface, in addition to taping nearby areas to keep the varnish off.

Because of that, I highly recommend using quality products over cheaper, lower cost options which will mean your boat needs revarnishing far more often.

International Perfection Plus two-part varnish

Best polyurethane boat varnish

International Perfection Plus is a well-known two-pot polyurethane

International Perfection Plus (sold in the US under the Interlux brnad) is arguably the best overall marine spar varnish on the market. This two-part polyurethane formulation is not only the most aesthetically spectacular, but also the most durable and longest lasting when exposed to UV.

This two-part product is applied to bare wood after careful sanding and degreasing and can be rolled/brushed or sprayed. It uses a proprietary Interlux thinner and one’s results will be excellent if one follows the recommended procedures to the “t.”

Of all the boat varnish products on this list, this two-part product is probably the least DIY-friendly.

Reasons to buy

• Most durable marine varnish in terms of hardness and flexibility • Best UV resistance • Most beautiful (glossy) varnish if applied properly • Hardness and longevity makes it a prime contender to redo cabin soles and floor boards (after proper surface prep)

Reasons to avoid

• Difficult application for inexperienced laymen • Expensive

Total Boat Lust High Gloss Marine Varnish

Best value boat varnish

In recent years, Total Boat has become very popular offering products comparable—and sometimes superior—to the “big three” of Interlux, Petit, and Epifanes, at a fraction of the cost and their “Lust High Gloss Marine Varnish” is no exception. This one-part formulation uses linseed oil and a modified polyurethane base.

Cetol Marine Wood Finish

Best boat varnish for external teak

Cetol has been making alternative wood finishes for a long time. While this product does not have the aesthetic beauty of freshly applied gleaming varnish, it lasts far longer and stands up to UV better than every one-part varnish on this list.

When I had peeling varnish on my 1987 Ericson 38-200 sailboat moored in the tropical Florida Keys, I elected to use Cetol’s “Natural Teak” offering in lieu of varnish and found it incredibly easy to apply and long-lasting, requiring no surface prep to speak up but a quick hand sand and power wash. For outside teak, Cetol cannot be beat.

• Incredibly easy to achieve satisfactory results • Affordable • Long-lasting even when exposed to UV

• Not as beautiful as real varnish • Softer and less durable to impact/abrasion compared to most varnishes, especially polyurethane formulations

Miniwax Helmsman Spar Urethane

The last product featured on our list is Miniwax’s one-part polyurethane spar varnish. While not the most beautiful finish available, this product is durable (hard and abrasion-resistant), easy to use, and very affordable, making it a good choice for touching up one-part varnishes inside a boat’s cabin.

For repairing, touching up, or even redoing cabin soles, this would also be a decent budget option and therefore is included on this list. Unlike the many UV-resistant offerings on this list, Miniwax Helmsman is not very UV-resistant and therefore is not recommended outdoors.

• Very affordable, even for a gallon • One-part polyurethane enhances durability and longevity over alkyd-based products • Good for sailors on a budget needing to repair and touch up existing interior varnish

• Not as beautiful as alkyd-based marine spar varnished • Not very UV-resistant • Yellows in sunlight

Which type of boat varnish to choose?

Varnishing often appears to be a simple task, but there’s a bewildering choice of boat varnishes on the market, writes Rupert Holmes.

An understanding of the qualities of different types of varnish is needed to choose the optimum one for each purpose. This is particularly true for exterior woodwork which has to withstand the ravages of sun, rain and frost.

There are only a few basic types of varnish, although in many cases hybrid products are available, particularly alkyd/ tung oil and alkyd/modified urethanes that can offer a wider range of desirable properties.

Polyurethane boat varnish

Polyurethane varnishes are a harder option with good wear resistance, but they lack the flexibility of alkyds. In addition, they tend to sit more on the surface of the timber, so often do not adhere as well to the substrate, which can make them prone to flaking and chipping.

The lack of flexibility makes a pure polyurethane unsuitable for traditionally planked boats, but it can be ideal for plywood , as well as for cold moulded and strip planked hulls.

Polyurethanes are available as both one-pot and two-pot products, the latter giving a harder coating and faster cure, which allows multiple coats to be applied in one day.

N.B. One-pot polyurethane can be applied over two-pot varnish but not the other way round.

Ultra-flexible single-pot polyurethanes, such as Coelan have an elasticity of more than 300%. It can also seal cracks, is highly resistant to impact damage and doesn’t need overcoating for several years and can last twice as long as traditional varnishes.

The biggest downside is that it’s four or five times more expensive than typical basic alkyd varnishes, so up-front costs are higher, although its long term performance means the total cost difference will be smaller.

Many boat varnish products can be painted, sprayed or rolled

Tung oil varnish

Tung oil is also frequently used in traditional varnishes: it soaks in well and, although a pure tung oil product will usually cure very slowly, the final finish is very tough.

Solvent-based varnish

Traditional solvent-based one-pot alkyd varnishes are ideal for use with traditionally built wooden boats. The coating is soft but flexible, which makes it resistant to cracking when used on timber that expands when wet and contracts in dry summer weather. Additionally, the initial coats tend to soak into the timber effectively.

Epoxy resin

Epoxy resin can also be used to coat timber, but generally has poor resistance to ultra-violet light, so a varnish needs to be applied over the top. Beware inexpensive ‘yacht’ varnish sold in DIY stores – the low prices are usually easy to explain in terms of extended drying times or poor long-term performance when used outside.

Dealing with surface damage? Don’t delay!

Whatever type of varnish is used, don’t delay on sealing any areas of damage. The key priority is to keep water out, so don’t wait until you have time and suitable weather for a full repair – touch in the damaged area immediately.

This may not have a silky smooth finish initially, but don’t worry. Even if it’s a few weeks before you’re able to do a proper fix you know there won’t be any further degradation.

What Do Marine Varnishes Protect Against?

Marine varnish protects the surface of wooden boats and objects made from pine or any other type of wood that has been exposed to water against damage, corrosion, mold growth, UV degradation, scuffs, and abrasions. The best marine varnish for wood can be used on exterior and interior surfaces, so you only need to purchase one product for a film-forming finish. They can also protect against harsh weather conditions such as rain or humidity that might influence your best marine varnish for wood.

Different Types of Marine Varnishes

There are several types of marine varnishes available in the market, and choosing the right one can be confusing. Here are the six different types of marine varnishes:

• Traditional Varnish: Natural resins, such as linseed oil, tung oil, and pine tar are the essential components of traditional varnish that coat surfaces to a deep luster. This finish is very resilient but requires multiple coats for completion as well as a longer drying time than other finishes.
• Spar Varnish: Spar varnish is a specially designed exterior sealant that fuses natural and synthetic resins, making it resilient to ultraviolet rays, water damage as well as other harsh weather conditions. With this type of durability at your disposal, you’re sure to have long-lasting protection for your outdoor investments.
• Two-Part Varnish: Make your boat shine with two-part varnish. This high-performance product is composed of a resin and hardener that when combined, form an incredibly long-lasting finish. Due to its durability, this type of varnish is commonly used in marine applications and boats alike. So give your vessel the protection it deserves – go for two-part varnish today.
• Epoxy Varnish: For superior protection against water and UV rays, the epoxy varnish is your go-to solution. Boats and other marine applications reap the most benefit from this innovative type of varnish, made with powerful epoxy resin for a hardy finish that will stand up to even the toughest conditions.
• Polyurethane Varnish: Polyurethane varnish is a resilient, waterproof solution that provides long-lasting protection against the elements and UV rays. It’s an excellent choice for outdoor furniture and decking surfaces, as it maintains its strength over time despite regular exposure to rain or sunlight.
• Acrylic Varnish: For a protective finish that can withstand the elements, the acrylic varnish is your answer. Made with acrylic resin and offering resistance to water damage and sun rays alike, this type of varnish works wonders on all indoor wood surfaces.

Benefits of Marine Varnish

Protection against water and moisture.

Applying a layer of marine varnish to wooden surfaces helps create an impermeable shield that prevents water from infiltrating and causing damage. This is especially important for boats, docks, or any other structure which are regularly exposed to moisture. Marine varnish guards against wood rot, warping, swelling, and cracking brought on by prolonged exposure to humidity.

Take a wooden dock that is consistently exposed to water, for example. Without the appropriate protection and maintenance, it can rapidly deteriorate and become hazardous. By coating it with marine varnish though, you can protect the wood from damage caused by moisture; thus preserving its longevity for many years.

UV Protection

Exposing wood to extended amounts of sunlight can cause it to lose its vibrancy and become weakened, not just in terms of color but also strength. The use of marine varnish helps protect the wooden surface from solar radiation by providing a UV filter. Consequently, these filters help maintain the quality of your wood’s appearance for years on end while preventing any discoloration or fading that might otherwise occur without this protective layer in place.

Durable and long-lasting finish

Marine varnish is crafted to ensure toughness and durability, even in harsh conditions. Saltwater, humidity, and extreme temperatures can all be tolerated with this veneer – making it the perfect solution for boat decks, dockside areas, or any other exterior wood surfaces exposed to tough elements. With marine varnish coating your outdoor furniture you are sure that its beauty will stay intact no matter what Mother Nature throws at it.

Unlike other finishes, marine varnish offers enduring protection that can continue for up to 10 years or even more when adequately cared for.

Enhances the natural beauty of wood

Boats can be a work of art, and marine varnish helps to bring out their natural beauty. This clear finish enhances the wood grain and texture so that it pops – creating an eye-catching look with stunning results. In other words, the marine varnish is essential for any boat to fully appreciate its unique aesthetic.

As an example, think of a sailboat with magnificent teak decking. Enhancing its innate beauty by varnishing it can make the wood appear more eye-catching and timelessly classic at the same time.

Resistant to scratches and abrasions

Marine varnish stands apart as an impenetrable finish that resists scratches and abrasions. For areas of your home or business that are subjected to regular use, the marine varnish is the ideal choice for keeping surfaces looking pristine.

Consider, for instance, a dock of wood utilized to load and unload boats. Unprotected wood surfaces are prone to becoming scuffed or scraped easily; however, with the application of marine varnish as a protective layer these abrasions will be guarded against so that your wooden dock remains in pristine condition over many years.

Reduces maintenance requirements

Marine varnish gives a robust and enduring finish, thereby reducing the need for the upkeep of wood surfaces. Unlike other finishes which may necessitate frequent application or sanding, marine varnish offers long-term protection that requires little maintenance. This can be particularly beneficial for boat owners, who may not have the time or resources to perform regular maintenance on their vessels. By using a marine varnish, they can ensure that their boat remains in good condition with minimal effort.

Can be used on a variety of wood surfaces

Marine varnish is a multifunctional finish that can be utilized to protect various wooden surfaces, from boats and docks to outdoor furniture. For instance, think of a deck exposed to the elements – sun, rain, or snow – it’s the perfect place for marine varnish! With its robustness and versatility in mind, there are countless applications where this protective coating should not be overlooked. By applying a marine varnish, the deck can be safeguarded against damage caused by these elements, and its beauty preserved for many years.

Marine varnish is a remarkably adaptable finish that can be applied to boats, docks, decks, and outdoor furniture. This makes it the perfect choice for any application requiring an effective layer of protection against harsh weather conditions.

Consider a wood deck, exposed to all the elements nature has to offer such as sun, rain, and snow. Applying marine varnish will protect this type of surface from wear and tear over time, ensuring that it requires less maintenance in the long term. Similar logic applies to outdoor furniture which is also subject to diverse weather conditions; protecting them with marine varnish can dramatically extend their lifespan and reduce upkeep requirements.

Provides a glossy or satin finish

Marine varnish is renowned for its ability to provide a stunning glossy or satin finish that truly brings out the natural beauty of wood. Whether you desire a low sheen or high gloss, marine varnish has it all due to its heightened resin and oil content which together create an ultra-durable surface capable of reflecting light and lending deep vibrancy to any type of timber.

Disadvantages of Using Marine Varnish

Longer drying times.

Although marine varnish is renowned for its impressive durability and long-lasting protection, it, unfortunately, takes longer to dry than other finishes. Depending on the specifics of each application such as the type of varnish and environmental conditions, drying times could range anywhere from a few hours up to several days. However, due to this extended curing period, you can rest assured that your project will be secure against even the harshest weather conditions.

Requires multiple coats

Applying multiple coats is a common requirement for marine varnish, as it lacks the same thickness and strength in comparison to other wood finishes. Consequently, you must layer on several layers of this finish to protect your woodwork and achieve your desired level of aesthetic quality.

More expensive than regular varnish

Marine varnish is costlier than other wood finishes due to the exceptional durability and longevity it provides. This is because marine varnish contains increased resin levels, as well as additional ingredients, which increase its production costs. Furthermore, this type of finish necessitates multiple coats be applied; thus increasing labor-related expenses that are associated with using a marine varnish finish.

Can be challenging to apply

Applying marine varnish, especially for those with limited experience with the process, can be tricky. Its thinner consistency compared to other finishes makes it more vulnerable to dripping and streaking while its extended drying period can make achieving an even application in humid or damp climates a challenge.

Not suitable for all types of wood

Marine varnish can be an ideal option for many wood surfaces, yet it may not always deliver the best results. For instance, when applied to excessively porous or oily woods, the marine varnish will likely fail to adhere properly and produce a sub-par finish. To ensure success with this product on certain types of wood, proper preparation or conditioning is necessary before application.

Can yellow over time

If you’re looking for a varnish that won’t discolor your wood over time, it’s important to invest in one of high-quality containing UV inhibitors or other additives. Such products can prevent yellowing due to prolonged exposure to UV light and the environment. Marine varnishes without these features are more likely to cause an undesirable amber tone on wooden surfaces as they age. Additionally, regular maintenance and cleaning can also help to prevent yellowing and extend the life of the finish.

Factors To Consider When Choosing The Best Marine Varnish for Wood

The type of wood being used.

Before selecting the optimal marine varnish for wood, it is essential to identify the kind of timber being used. Different woods have distinctive properties that influence their absorption and retention of varnish. Some kinds such as teak or mahogany contain natural oils which can make adhesion difficult; consequently, these must be taken into consideration when deciding on what product will ensure proper coverage. Woods like pine are more susceptible to harm from rain and other elements due to their softer, porous nature. Therefore, you must select a marine varnish tailored to the material used for it to provide maximum protection.

The location and environment of the wood

When selecting marine varnish, it is essential to think about where and how the wood has been exposed. Woods that are subject to intense conditions such as saltwater, ultraviolet light, and extreme temperatures necessitate a more reliable and protective coating than those in calmer environments. To further ensure longevity, woods located in damp climates must be rubbed with a varnish that can stand up to these particular conditions without eroding their defensive qualities.

The level of protection required

When selecting a protective coating for your wood, its location is of paramount importance. If it’s exposed to harsh environmental conditions like those found in marine settings, you’ll need to invest in higher-grade protection against water and UV rays. Alternatively, if the wood resides in an area where these elements are less present, lower levels of varnish may suffice.

The desired finish

When selecting a marine varnish for your wood, the desired finish should be kept in mind. These types of paints come in varying finishes from high gloss to satin, so it’s important to consider what look you’re going for before making any decisions. Ultimately, the choice is purely based on personal preference and desired aesthetic.

The application method

The application process is integral in the selection of a marine varnish. There are many types available, some of which can be brushed on while others require spraying or rolling. To create that perfect even finish you seek, make sure to select one that can be applied with your desired method; otherwise, it may not provide satisfactory results.

The drying time

When selecting the ideal varnish, one needs to consider drying time. Certain marine varnishes may require a longer wait before they are ready for use or exposure to harsh weather conditions – and this is something you must take into account when making your choice. Thus, you must select an option with a drying time appropriate for its purpose.

The durability of the varnish

When selecting a marine varnish, it is essential to consider its durability. Although all marine varnishes have been crafted for longevity, some are more durable than others. Opt for one that will protect the wood from any conditions it may encounter and guarantee an optimal level of protection.

The cost of the varnish

When deciding on a marine varnish, not only is it essential to take the level of protection into account but also its cost. Prices may range greatly among different products, so prudently select one that fulfills your needs without breaking the bank. You should keep in mind though, that quality costs more upfront; nevertheless, you can save money over time because premium brands require fewer reapplications or repairs.

Polyurethane does have a few advantages of its own; it is easier to apply and dries rapidly compared with the longer drying time typical of marine varnish. Polyurethane is more water-resistant than marine varnish and might be a wiser choice for projects that come in contact with moisture. Ultimately, the ideal decision between polyurethane or marine varnish relies on your specific project requirements as well as the wood you are working with.

How to Apply The Best Marine Varnish for Wood In 8 Steps

When it comes to applying marine varnish to wood, it is important to follow the right steps to ensure a smooth and long-lasting finish. Here are eight steps to consider:

Step 1: Sanding the wood

Before applying marine varnish, you need to sand the wood to create a smooth surface. Start with coarse sandpaper and gradually move to a finer grit sandpaper to create a smooth surface. Make sure to remove all the dust and debris using a vacuum or tack cloth.

Step 2: Cleaning the surface

The wood surface needs to be clean and free of any oils, dirt, or debris. Use a wood cleaner or denatured alcohol to clean the surface thoroughly.

Step 3: Applying the first coat

Apply the first coat of marine varnish using a brush, roller, or sprayer. Make sure to apply an even coat and follow the manufacturer’s instructions regarding the recommended thickness of the coat.

Step 4: Sanding between coats

After the first coat dries, sand the surface with fine-grit sandpaper. This will help the subsequent coats adhere better to the surface.

Step 5: Applying subsequent coats

Apply subsequent coats of marine varnish following the same process as the first coat. Make sure to apply thin coats and sand between coats.

Step 6: Sanding the final coat

After the final coat dries, sand the surface with very fine grit sandpaper. This will create a smooth and even surface for the final finish.

Step 7: Buffing the surface

Buff the surface using a buffing pad or cloth to create a glossy finish.

Step 8: Maintaining the finish

To maintain the finish of the marine varnish, make sure to clean the surface regularly and reapply a coat of varnish when necessary.

Tips for Maintaining Marine Varnish Finish

• Avoid exposing the wood to extreme temperatures or moisture: To keep your marine varnish finish looking its best, be sure to protect the wood from extreme temperatures and moisture. This involves staying away from direct sunlight as well as shielding it against rain, snowfall, or humidity. Neglecting this will cause the lacquer to crack or peel which can make for an unsightly outcome that is difficult to fix.
• Use a soft-bristled brush or microfiber cloth to clean the surface: To keep your wood looking pristine, it is essential to utilize a soft-bristled brush or microfiber cloth for cleaning. Refrain from using any abrasive scrub brushes or materials that could potentially scratch the finish and damage the varnish. Additionally, make sure you use a gentle cleaner specifically formulated for marine varnishes to simplify maintenance while effectively retaining its glossy luster.
• Avoid using harsh chemicals or abrasive materials: To preserve the elegance of your wooden furniture, be careful to avoid any harsh chemicals or abrasive materials. These can strip away the protective varnish and accelerate wear and tear on its surface. Instead, opt for a mild cleanser that won’t cause scratches or other damage when you clean it.
• Apply a fresh coat of varnish periodically to maintain the finish: Over the years, the marine varnish may become worn or lose its shine. To keep your wooden structures looking their best and well-protected, it is essential to apply a new coat of varnish on occasion. The frequency of this task depends on the level of utilization and exposure; however, as a general guideline, you should consider renewing the surface every 1-2 years for optimal results.
• Store the varnish in a cool, dry place to prolong its shelf life: Prolong the shelf life of your extra varnish and guarantee its usability for upcoming projects by storing it in a cool, dry place. Keeping it away from direct sunlight or humid environments is key as this could cause irreparable damage and render your leftovers unusable.
• Consider using a UV-resistant varnish: If your wood surface is exposed to a lot of sunlight, you may want to consider using a UV-resistant varnish. This type of varnish is specifically designed to protect against the damaging effects of the sun’s UV rays, which can cause the varnish to fade or break down over time.

Choosing the Right Brush for Applying Marine Varnish

Making the proper choice of the brush when applying marine varnish can prove to be invaluable. Natural bristle brushes make great use of animal hair, such as badger and hog bristles, while synthetic brushes are manufactured using a combination of nylon or polyester fibers. Deciding on which type is right for you will depend on your preferences and needs.

Natural bristle brushes offer several advantages, such as their capability to contain more varnish for even coating. Nonetheless, these brushes can be costly and are not suited for use with water-based varnishes. On the flip side, synthetic brushes provide a cost-effective option that is ideal for multiple types of coatings or finishes. When selecting a brush for marine varnish, the size and shape should also be taken into account. A tool that is too small may require more effort to apply correctly, while an oversized one can lead to excess drips and wasted varnish. Generally speaking, brushes between 2-3 inches wide are ideal for most applications involving marine varnish application; not only will this save time but money as well.

To guarantee a long lifetime and superior performance, it’s essential to mindfully maintain your brush. Following each use, your brush should be cleaned with the right solvent that is suitable for the type of varnish you employed. Subsequently, rinse and dry thoroughly before storing in an airy atmosphere devoid of moisture.

How to Sand Wood for Marine Varnish Application

Before applying marine varnish to wood, it’s important to properly sand the surface. Sanding helps to remove any imperfections, smooth out rough patches, and create a clean and even surface for the varnish to adhere to. Here are some tips f sanding wood for marine varnish application:

Choosing the right sandpaper grit for different wood surfaces: The abrasive quality of sandpaper is determined by its coarseness or fineness. When prepping wood for marine varnish, a medium-grit paper between 100 and 120 should be used to achieve the required balance of smoothness and durability. For rougher materials, select something in the range between 80–100 while finer surfaces need higher grits from 120 up to 150.

The importance of proper sanding techniques: Sanding is best done with the natural grain of the wood, utilizing a back-and-forth pattern. To keep the sandpaper from creating patchy surfaces, make sure to continually move it in one direction following the grain’s lines – this will help preserve and protect your wooden material.

Tips for avoiding common sanding mistakes: A frequent mistake when sanding is applying too much force, which can cause the sandpaper to generate scratches or divots in the wood. Likewise, using an excessively fine grit of sandpaper too early on could make it difficult for varnish to stick securely onto the surface. Therefore you must be precise and take your time while sanding instead of rushing through it haphazardly.

How to Remove Marine Varnish from Wood

When it comes to removing marine varnish from wood, several methods can be used depending on the extent of the finish, the type of wood, and the tools available.

Tools and materials

• Chemical stripper
• Protective gear, such as gloves, goggles, and a respirator.

Here are four common methods for removing old varnish:

• Sanding: For those seeking to revitalize their aged varnish, sanding is the most popular method. By utilizing either a manual or electric sander, you can slowly strip away layers until the desired finish is achieved – all while avoiding toxic chemicals! It’s an effective way of purging old coats; however, it may be time-consuming and messy at times.
• Chemical stripping: Chemical strippers are remarkably effective solvents that dissolve existing varnish, making it easy to remove. Although quicker than sanding, this process requires extra preparation and can be quite messy. For safety reasons, read the product label carefully and wear protective clothing such as gloves at all times while using chemical strippers.
• Heat gun: For speed and ease in removing varnish from surfaces, a heat gun is an excellent tool. However, it’s important to take safety precautions when using this device. You must wear protective gloves and work in an area with proper ventilation to avoid any hazardous situations. With the right steps taken care of, simply use your putty knife or scraper to scrape away the softened varnish quickly and efficiently.
• Planing: With the use of a woodworking plane, you can easily remove the top layer of the surface and its varnish from flat surfaces or large areas. Although it requires some expertise to master this technique, practice makes perfect.

Tips for minimizing damage to the wood surface during varnish removal:

• Work slowly and carefully to avoid gouging the wood surface.
• Use a scraper or putty knife to gently remove the varnish, working with the grain of the wood.
• If using a heat gun, keep the nozzle moving and avoid focusing on one spot for too long to prevent scorching or burning the wood.
• If using a chemical stripper, follow the instructions carefully and avoid leaving the product on the wood for too long.
• When sanding, start with a coarse grit sandpaper and gradually work your way up to a finer grit to avoid scratching the wood surface.
• Use a sanding block or machine to ensure even sanding.
• Remove all dust and debris from the wood surface before applying a new finish.
• Consider seeking professional help if you’re unsure about how to proceed or if the wood surface is particularly delicate or valuable.

Environmental and Health Considerations When Using Marine Varnish

Marine varnish contains potentially hazardous chemicals that can have negative environmental and health impacts if not used and disposed of properly. Here are some environmental and health considerations to keep in mind when using marine varnish:

• Potential environmental impact: Applying marine varnish can be hazardous to the environment if not disposed of responsibly, as these chemicals may contaminate soil and water sources that are critical for plants and animals.
• Proper disposal: It is imperative to discard unutilized varnish and other materials correctly. Ensure you contact your local waste management institute to ascertain if they have special rules for disposing of hazardous substances such as varnish.
• Precautions in enclosed spaces: If you are applying varnish in a limited or not well-ventilated area, it is essential to take safety measures for your well-being. Wear a respirator and other security gear while ensuring there is an abundance of fresh air circulating throughout the space. Use of protective clothing and equipment: When applying marine varnish, it’s important to wear protective clothing like gloves and long sleeves to prevent skin contact. You should also wear eye protection and a respirator to avoid inhaling any fumes.
• Consider alternatives: If you worry about the environmental and health consequences of using marine varnish, why not switch to a more eco-friendly or non-toxic alternative? Look for labels that say low-VOC or water-based, but if those don’t appeal to you, consider natural finishes like oils or waxes instead.

What is the difference between marine varnish and regular varnish?

Marine varnish is specifically designed to withstand exposure to harsh marine environments, such as saltwater, UV rays, and moisture. It contains additives that provide extra protection against these elements. Regular varnish, on the other hand, is designed for interior use and provides less protection against environmental factors.

The number of coats of marine varnish needed depends on the level of protection desired and the condition of the wood surface. Typically, two to three coats are recommended, with sanding between each coat for better adhesion.

How long does marine varnish take to dry?

The drying time of marine varnish can vary depending on the product and environmental conditions. Typically, it can take 24 to 48 hours for each coat to dry. However, it is important to follow the manufacturer’s instructions for specific drying times.

Can I apply marine varnish over an oil-based finish?

Yes, it is possible to apply marine varnish over an oil-based finish, but it is important to ensure that the surface is clean and sanded for proper adhesion.

Can I apply marine varnish over painted wood?

No, it is not recommended to apply marine varnish over painted wood as it may not adhere properly and can result in an uneven or peeling finish.

How often do I need to maintain the marine varnish finish?

The maintenance frequency of the marine varnish finish depends on the level of exposure to environmental elements and wear and tear. Typically, a fresh coat of varnish may need to be applied every 1 to 2 years to maintain the protective finish. Regular cleaning and inspection of the surface can help identify any areas that need touch-ups or repairs.

The finest marine for wood is a must-have. When you want your furniture or boat to last as long as possible on wood finish , you should use the greatest marine varnish.

What Is Marine Varnish?

The marine varnish is a formula that acts as a protective film against wear and chipping. It’s specifically designed for wood exposed to water. Before now, varnishes comprised resin and pine sap. Now, varnishes feature simpler chemical ingredients like Tung oil, phenolic, and alkyd resin, making painting much easier.

Best Marine Varnish for Wood Buyer’s Guide

When in the market for the best marine varnish for wood, there are essential factors that you must consider to ensure that you make no mistake. Below are some of these factors;

Types of a Marine Varnish

You will encounter several types of marine varnishes when in the market for one. Marine varnishes exist in the following types as Tung Oil mixture, Water-based and Oil-based Polyurethane, Exterior Varnish, Spar Varnish, Two-Part Varnish, and Acrylic Varnish.

As I earlier explained in this article, classic varnish comprised of resin and pine sap. Modern marine varnishes now comprise tung oil, phenolic resins, and alkyds.

Varnishes with tung oil offer gloss finishes and harden after application. This makes them great for coating boats and other things that come in contact with water.

Water-Based and Oil-Based Polyurethane is another type of varnish. They contain chemical components that harden quickly when applied to a surface. Unlike oil-based poly, water-based results in crystal clear finishes and doesn’t give off yellow color. However, it is not durable as oil-based poly.

Exterior Varnish is for exterior use. It comes with UV protection that makes the varnish suitable for outside utilization. This varnish makes it impossible for mold to grow in the wood because of its deep penetration.

Spar varnish is mostly used for coating boats since they come in contact with water constantly.

The two-part varnish is a finish that comes with a base and a hardener. These two components are mixed in the right combination to give the best coating result. Two-part finishes offer maximum abrasion resistance and dry super quickly.

Acrylic varnish dries quickly and non-toxic. Like Exterior Varnish, acrylic varnish comes with UV light protection, so you can use it both on the inside and outside.

The acrylic varnish is also clear after application. However, it has low penetrating power but it’s not corrosive or gives off a bad odor. This makes it safe for use.

Ease of Cleaning

You can’t be too careful with using varnishes, as they sometimes spill accidentally. That’s why you need a formula that’s easy to clean. You will find it more comfortable to clean such a formula when it spills during use.

The varnish should be utterly resistant to abrasion and scratches and last for an extended time. This will minimize expenses and save you money a great deal.

Ease of Use

Some varnishes are difficult to use, especially for those who are just starting. As a beginner, you should use a product that’s easy to apply. You should use a product that you can handle comfortably should mistakes occur during painting.

Drying and Curing Time

Every varnish has its drying and curing time. However, you should avoid those that take time to dry, as they can complicate your schedule. Plus, varnishes that take time to dry are susceptible to dust and debris accumulation, affecting the coating result.

Safety and Maintenance Tips When Using a Marine Varnish

Maintaining a marine varnish will make it last longer and maximize its effect. Therefore, you need to take care of it and ensure that it’s kept in a safe place.

Careless handling of a marine varnish can jeopardize your safety. Marine varnishes are flammable. Exposure to fire and direct heat will cause an explosion.

Before you can begin to apply a marine varnish, make sure the area is properly ventilated. Painting outdoors, especially in the morning is most preferred. Also, you must wear safety gear like gloves, goggles, and a respirator for optimal security.

Although some marine varnishes come with UV protection, direct sunlight can affect the drying process. So you should either paint in the morning or late in the afternoon to avoid fast drying.

How to Apply a Varnish

• Clean the surface and prepare the surface for the first coat.
• Rough the surface up with 80-grit sandpaper so that the coat can stick.
• Thin the first coat with white spirit for oily varnishes and water for water-based varnishes.
• Apply the first coat with a roller. You can also use a paintbrush.
• Make sure the coat is dried properly.
• If you can see some bubbles on the surface, sand it with 180-grit sandpaper or any other fine-grit sandpaper to smoothen.
• Apply the second coat. This time, don’t dilute it.
• Wait for it to dry.
• If you wish to apply the third coat, repeat the process from step 7

What is the difference between spar varnish and marine varnish?

Spar varnish, also known as spar urethane, and marine varnishes are nearly similar. Both protect the wood from water and moisture damage. The major difference between spar varnish and marine varnish is that spar varnish can be oil-based or water-based, while the marine varnish is mainly water-based.

Is marine varnish better than polyurethane?

It depends on the surface you intend to apply the finish. For doors and exterior surfaces, the marine varnish is best to use because of the chemical properties and moisture-resistant abilities. Polyurethane is best used for items inside the home or interior use.

What makes varnishes better for exterior use than polyurethane is due to its low toxicity. They are more flexible and offer better protection against extreme weather conditions.

How long does marine varnish last?

Marine varnish typically lasts for more than ten years, although pigments, temperature, and chemical agents may affect durability. For instance, exposure to direct sunlight can minimize its longevity.

What is the best exterior clear coat for wood?

The best exterior clear coat for wood is marine spar varnish. This finish contains primary ingredients such as linseed and alkyd resin to offer optimal protection to the wood.

Is marine varnish waterproof?

The marine varnish is waterproof. However, its waterproof features are lost when it is used in certain woods. Before you can begin coating, you have to ensure if the varnish’s components are compatible with the surface you intend to paint.

Conclusion – Best Marine Varnish for Wood

Purchasing the best marine for wood is non-negotiable. If you want your furniture or boat to last as long as possible, you need to use the ideal marine varnish.

Choosing the Best Marine Varnish

When choos­ing the best marine var­nish, it is impor­tant to con­sid­er the appli­ca­tion and envi­ron­ment. If the wood is exposed to direct sun­light and harsh ele­ments, it is best to choose a polyurethane marine var­nish. If the wood is not exposed to direct sun­light and harsh ele­ments, an alkyd marine var­nish may be the bet­ter choice.

Look for a marine var­nish that offers excel­lent dura­bil­i­ty to with­stand the harsh con­di­tions encoun­tered in a marine envi­ron­ment. It should be resis­tant to UV rays, salt­wa­ter, mois­ture, and tem­per­a­ture fluc­tu­a­tions.

UV resis­tance is cru­cial to pre­vent the var­nish from fad­ing, yel­low­ing, or degrad­ing under pro­longed expo­sure to sun­light. Opt for a var­nish with high UV resis­tance to main­tain the appear­ance and integri­ty of your wood sur­faces.

Con­sid­er the desired lev­el of gloss for your wood sur­faces. Marine var­nish­es typ­i­cal­ly offer a range of gloss options, from high gloss to satin or mat­te fin­ish­es. Choose a var­nish that aligns with your aes­thet­ic

Look for a marine var­nish that is easy to apply, even for indi­vid­u­als with lim­it­ed expe­ri­ence. Con­sid­er fac­tors such as brusha­bil­i­ty, self-lev­el­ing prop­er­ties, and whether it requires thin­ning or mul­ti­ple coats for prop­er cov­er­age.

The dry­ing time of the var­nish is an impor­tant con­sid­er­a­tion, espe­cial­ly if you have time con­straints or need to com­plete the project with­in a spe­cif­ic time­frame. Some var­nish­es have quick­er dry­ing times, while oth­ers may require longer cur­ing peri­ods.

Ensure that the marine var­nish you choose is com­pat­i­ble with the type of wood you are work­ing with. Dif­fer­ent var­nish­es may have spe­cif­ic rec­om­men­da­tions for use on par­tic­u­lar wood species, so ver­i­fy com­pat­i­bil­i­ty before appli­ca­tion.

Con­sid­er the ease of main­te­nance and repair for the var­nish. Look for a var­nish that allows for easy touch-ups or refin­ish­ing with­out requir­ing com­plete strip­ping and reap­pli­ca­tion.

Application

When apply­ing marine var­nish, it is impor­tant to fol­low the man­u­fac­tur­er’s instruc­tions. Marine var­nish must be applied in thin, even coats for best results. A foam brush or roller is the best way to apply the var­nish, as it will help pre­vent any drips or runs. The var­nish should be allowed to dry com­plete­ly between coats, and the num­ber of coats will depend on the type of var­nish being used.

Preparing the Surface

Before apply­ing the marine var­nish, it is impor­tant to prop­er­ly pre­pare the sur­face. The wood should be sand­ed with a fine grit sand­pa­per and all debris should be removed. The wood should also be wiped down with a damp cloth to remove any dust or dirt. Any flaws in the wood should be filled in with a wood filler before apply­ing the marine var­nish.

Applying the Marine Varnish

Once the wood is pre­pared, the marine var­nish can be applied. It is impor­tant to work in a well-ven­ti­lat­ed area and to wear pro­tec­tive cloth­ing, such as gloves and a res­pi­ra­tor mask. A foam brush or roller is the best way to apply the var­nish, as it will help pre­vent any drips or runs. The var­nish should be allowed to dry com­plete­ly between coats, and the num­ber of coats will depend on the type of var­nish being used.

Maintenance and Repair

To keep marine var­nish look­ing its best, it is impor­tant to per­form reg­u­lar main­te­nance and repairs. The wood should be cleaned reg­u­lar­ly with a mild soap and water solu­tion. If the wood becomes scratched or dam­aged, it should be sand­ed and re-var­nished.

Repairing Scratches

Scratch­es in the marine var­nish can be repaired by sand­ing them with a fine grit sand­pa­per and then re-var­nish­ing the area. It is impor­tant to use a fine grit sand­pa­per, as a coarse grit sand­pa­per can dam­age the wood.

Repairing Cracks

Cracks in the marine var­nish can be repaired by apply­ing a flex­i­ble adhe­sive to the crack and then re-var­nish­ing the area. It is impor­tant to use a flex­i­ble adhe­sive, as it will help pre­vent the crack from return­ing.

What is the best varnish for a boat?

The best var­nish for a boat depends on the type of wood and the desired fin­ish. Gen­er­al­ly, for out­door use, a high-qual­i­ty marine spar var­nish is rec­om­mend­ed. It is typ­i­cal­ly a long-last­ing, pro­tec­tive fin­ish that will retain its gloss and flex­i­bil­i­ty in the harsh marine envi­ron­ment. When apply­ing any var­nish, it is impor­tant to ensure the wood is prop­er­ly pre­pared and the var­nish is applied cor­rect­ly in mul­ti­ple thin coats.

When select­ing a marine spar var­nish, con­sid­er the cli­mate you are in, as some are bet­ter suit­ed to warm and humid cli­mates and oth­ers to cold cli­mates. Also con­sid­er any spe­cif­ic needs you have, such as UV pro­tec­tion or a high-gloss fin­ish. It is often ben­e­fi­cial to choose a var­nish that con­tains UV inhibitors and mildew­cides to pro­tect your boat from the ele­ments. Look for a var­nish that is easy to apply, has good adhe­sion and is resis­tant to crack­ing, peel­ing and yel­low­ing.

What is the hardest marine varnish?

The hard­est marine var­nish is a var­nish that con­tains high amounts of UV absorbers, chem­i­cal sta­bi­liz­ers and alkyd resins. This com­bi­na­tion of ingre­di­ents pro­vides a hard­er and more durable fin­ish that is resis­tant to crack­ing, fad­ing and dis­col­oration over time. It also pro­vides supe­ri­or pro­tec­tion from salt­wa­ter and oth­er envi­ron­men­tal ele­ments.

It is also for­mu­lat­ed to be resis­tant to abra­sion and wear, mak­ing it an ide­al choice for boats and oth­er marine appli­ca­tions.

Con­sid­er your spe­cif­ic needs and pref­er­ences to choose the marine var­nish that best suits your project and pro­vides opti­mal pro­tec­tion for your boat’s wood sur­faces.

What is the difference between marine varnish and regular varnish?

It offers enhanced dura­bil­i­ty and pro­tec­tion com­pared to reg­u­lar var­nish­es, mak­ing it suit­able for boat appli­ca­tions.

How many coats of marine varnish should I apply?

The num­ber of coats required can vary depend­ing on the spe­cif­ic marine var­nish and the con­di­tion of the wood sur­face. In gen­er­al, it is rec­om­mend­ed to apply mul­ti­ple thin coats rather than a sin­gle thick coat. This helps achieve prop­er cov­er­age, improves adhe­sion, and allows for bet­ter con­trol over the fin­ish.

Can I apply marine varnish over an existing finish?

It is pos­si­ble to apply marine var­nish over an exist­ing fin­ish, pro­vid­ed that the sur­face is prop­er­ly pre­pared. The exist­ing fin­ish should be clean, dry, and free from any loose or flak­ing mate­r­i­al. Light sand­ing or strip­ping may be nec­es­sary to cre­ate a suit­able sur­face for the marine var­nish to adhere to.

The Best Marine Varnishes for 2024

Boats often come in contact with a lot of different pressures such as waters, rocks, and even animals. On top of this, it is also exposed to the sun’s harmful UV rays all of the time. With this, the need for marine varnish became extremely popular among boat owners. It is actually one of the most effective things that any boat owner can do to preserve the beauty of their boat.

However, it is not that easy to find the perfect marine varnish that will work wonders for our boats. We have to experience a lot of trial and errors before we finally find what specific marine varnish is best for our lovely ships.

Do you want to keep your boat as pristine as possible? Read on to know about the top 10 best marine varnishes!

1. Rust-Oleum 207008 Marine Spar Varnish

2. epifanes clear varnish, 3. totalboat lust marine varnish, 4. system three 1855s16 marine spar varnish, 5. minwax 630500444 helmsman spar urethane, 6. interlux iva316/qt cetol natural teak varnish, 7. mccloskey man o’war spar marine varnish, 8. old masters 92304 spar marine varnish, 9. pettit captains varnish, 10. interlux y60/pt goldspar satin varnish, who is this for, factors to consider when buying a marine varnish, advantages and disadvantages of using a marine varnish, care and maintenance, frequently asked questions, best marine varnish reviews.

I was so stunned by this beautiful marine varnish! When I received it, I could immediately tell that it will perform amazingly. I sincerely appreciate that the company made sure that the application process will be easy! All I needed was a foam paintbrush to apply it on my boat’s surface and a good quality sanding sponge to smooth out the wood surface for a clean and even coat.

Unlike other varnishes, the company advises its customers to skip the thinner before using this product because it will affect the varnish’s performance by prolonging the drying time and increasing the chances of bubble formation.

Now, the most notable thing that I love about this product is that it dries so quickly! After the 1st layer that I applied on my boat, it only took roughly 2 hours for the spar varnish to dry. I am so flabbergasted because it was so convenient to use!

I love how I did not need to wait for at least 12 hours just to apply the 2nd coat of this marine varnish! This is such a good deal because not everyone has the time to let the varnish sink in. Although, you still have to sand the boat before applying the 2nd layer of varnish so that your application will glide as smoothly as butter!

As an oil-based marine varnish, it is better than a water-based marine varnish because it provides a more vivid color with a shine that does not look dull! Even though it is a little bit runny, its consistency does not affect its performance because it is oil-based. It sticks to the wood more comfortably, which is actually one of the reasons why it dries quicker!

• It does not require a thinning agent.
• Even application
• A quick drying time of 2 hours
• Can do two coats in one day
• Vivid and shiny
• It has a runny consistency

I have nothing to say but outstanding! I cannot get over the fact that this marine grade spar varnish performs exceptionally well. I am so excited to use this on my other boats because I’m sure that it will provide the perfect coating for protection and aesthetics!

First of all, I love how this product does not smell too strong! That’s one of the many things that I love about this epifanes marine spar varnish. Because of my countless attempts at finding the best spar varnish, I know how stinky some varnishes could be. It really is a hassle because some products have strong smells that give me a headache.

But this one was delightful to use because it almost does not have a strong chemical smell! I spent a lot of time using this spar varnish, and I can safely say that I did not experience any headaches.

I used a thinning agent before the first coat for this varnish because this product’s consistency is quite thick, almost similar to a syrup’s texture. Doing this resulted in a deep, high-gloss, and smooth finish! I cannot get enough of how beautiful the finished product is.

The company recommends a total of 8 coats, but I achieved my desired deepness and intensity with just five coats. Because of this, I have enough left varnish left for future use, which I sincerely appreciate!

I especially love that this product gives off a dark amber color. I prefer this type of finish because it made my boat look rustic yet fresh at the same time! And because it is on the darker side, it can cover old stains that may be present on your boat, so technically, it is a varnish and a light paint in one!

The wood on my boat started to look really nice once the spar varnish has dried. At the end of the day, it looked brand-new and ready to take on the fiery waters!

• It does not smell too strong.
• It did not give me headaches due to the chemical scent.
• Thick consistency
• Varnish and paint in one
• The recommended number of coats is 8

I think that is such a steal! For just half the container, I was able to apply five coats, and my boat looked very beautiful instantly. If I were you, I would get my hands on this beautiful spar varnish!

I received this totalboat gleam marine spar varnish; it was love at first sight! I immediately started to use it, and upon the initial application, I love how it enhances the woodgrain feature of my boat. Unlike other spar varnishes, this one does not try to eliminate the texture of wood; it makes it look more pleasing to the eyes!

Another thing that made my heart fall for this varnish is that it does not require the use of a sanding sponge or sandpaper. As I said, it aims to enhance the wood’s texture, so there is no need to even it out.

I also enjoy how with just six coats, I was able to finish varnishing my entire boat in one day. This made me fall head over heels for this product!

I also appreciate that this product features a slight tint that improves the overall design of the boat. No, it does not entirely cover up the boat’s original color; it makes the actual color brighter and more alive. I have had some experience with varnishes that dulls down the boat’s original hue, so I am happy that this one does not do that!

Lastly, the company offers two different types of varnish – one matte and one high gloss. Personally, I prefer a high gloss spar varnish because it lessens the appearance of scratches. However, some people enjoy matte varnishes, so kudos to TotalBoat for providing boat owners such as me with options!

Although it is quite thick, and I had to reapply varnish on some parts because, for some reason, the material does not adhere to it, I was still left with a beautifully-varnished boat at the end of the day!

• Improved my boat’s woodgrain texture
• It does not require sanding.
• Enhanced the color of the boat
• It has two different kinds of varnish
• I had to reapply varnish on several areas

To sum it up, I am so glad that I was able to try this product! For such a long time, I have been looking for the varnish that has a perfect balance between tint and gloss, and I finally found it in this product!

Upon receiving the product, I ordered both variants: satin and high shine. I decided to combine the two types of finish to get a more solid hue without losing the varnish glossiness.

I think I made the right decision! The end product is exceptionally smooth, glossy, and stable at the same time. I love how it is as soft as a baby’s butt… maybe even softer!

Because its consistency is quite thick, I used an HV/LP sprayer to apply it. This product applies like a dream. I’ve never used a marine varnish as smooth as this before. Therefore, the use of a thinning agent is totally necessary since it is viscous.

I also find its consistency to be quite thick. I love how this product really gave me the option to have my varnish on the thicker side or on, the thinner side. Well, I opted to thin it out a little bit using a thinning agent.

I love how it applies! For me, I would not use a bristled paintbrush with this product because there is a chance for bubble formation and streaky application. So, I used an HV/LP sprayer to apply it, and I honestly did not get tired at all!

I got so excited because I have never used a marine varnish that was as smooth as this before! I personally prefer mixing it with a thinning agent for the sprayer, but if you want it to be thicker, you may want to use a new paint roller to do the job.

Even though this does not dry as quickly as the other spar varnishes I have tried, I think those good things really do come to those who wait. As I used this product, I learned to be patient and to keep on trusting the process.

In the end, I got the best-looking boat ever! On top of that, this one also has superior saltwater protection for my boat. I can honestly tell you this: I think this is such a great deal!

• Available in satin and high shine
• Thick consistency for fuller application
• Best used with a paint sprayer
• Saltwater protection
• Excellent finish if both variants are mixed.
• Long drying time

Honestly, I think I got such an excellent deal with this product. This could easily be the best marine varnish UV protection!

This one is for the boat owners who prefer marine varnishes without any tint! This product from Minwax is a water based marine varnish, and this means that it is a clear gloss that does not have any color to it.

I love how this could be used on top of colored boats. Since it does not alter the existing shade that the ship has, this is a good option for those who prefer to maintain the current color, brightness, and contrast of their boats.

Its consistency is thin, mostly because it is water based. With this, I used a paint roller. I got the most seamless application because a thin consistency goes well with a roller! I am in awe that I only had to use a sanding sponge or sandpaper before applying the first coat. The succeeding layers did not require any sanding because they glide on like a dream!

Overall, it took me a total of 4 coats to get an excellent finish. However, I added an extra layer to be sure that the end product will be as beautiful and vibrant as possible.

I love how to apply this even over latex paint, unlike other varnishes with spar polyurethane as an ingredient.

This goes to show how dedicated the company is to provide us with quality products that won’t be inconvenient to use.

The only issue that I came across is that it tends to crack whenever I suddenly apply too much. I was able to remedy this by ensuring that each layer is skinny to avoid any separation of the varnish.

• It does not have a tint
• It does not affect the original color of the boat
• It can be used over latex paint
• It has a tendency to crack if too much is applied
• Thin application per layer is needed

This one is indeed a tremendous marine varnish to let the right color of your boat shine through. I highly recommend this beautiful marine varnish!

I have to say that this product is a rare breed! There are two common types of marine varnishes, and these are the high gloss and the matte variants. It is uncommon for the market to offer a satin varnish. Satin is a cross between a high luster and a matte finish; it has a shine, but it is also relatively flat. Basically, it is the best of both worlds!

My boat is made of a wood called teak. Honestly, I believe that this product from Interlux is the best marine varnish for teak! I did not have to use any unique tool to make it look splendid. No thinning agent and sandpaper had to be used because this boat varnish already does a great job in penetrating teak and, honestly, other types of wood effectively!

This product has a golden hue. It is the perfect shade for my boat’s wood! I love how it made my boat look expensive and well-kept. It also has a knack for giving a boat its personality!

I was able to see it personally because my boat’s color has already faded. But soon after applying this boat varnish, its color started to come alive! It slowly became brighter and radiant. Suddenly, my faded boat transformed into a beautiful ship with a rich and deep copper hue.

Even though this product can only be applied right above the waterline both for interior and exterior portions of the boat because it is not effective against saltwater, it is still not a bad deal because this varnish is not only useful for boats. It can also be used as an alternative for tables, chairs, and doors!

• Satin finish
• Penetrates teak effectively
• It has a golden hue
• Alternative varnish for tables, chairs, and doors
• Only useful above the waterline
• Not effective against harsh saltwater

Because of the fantastic quality that this product offers, I simply cannot get enough! I’m sure that I will be using it again soon for my other boats.

This marine grade spar varnish proves that a boat undergoes a lot of adverse conditions both while sailing and while being stored. As a varnish, I love how this product is very well-versed when it comes to being durable!

I am so amazed because it does not peel easily, unlike other marine varnishes that I have used in the past. It stays put for a long time, and it does not crack. It is very different from polyurethane-based varnishes because this one from McCloskey/Valspar screams flexibility. It has the power to adhere onto various surfaces, and it sinks deep into the wood quite decently.

It is made with tung oil instead of urethane. It can be seen as old-school because it does not have the synthetic material that modern varnishes contain, but whoever said that old-school is terrible? Actually, tung oil is useful, and it gives off a beautiful finish!

I specifically go crazy about this product because it is thick and pigmented enough to provide a certain degree of coverage. I love that it is useful as a corrector; it completely covers the tiny scratches and stains on my boat’s surface!

But still, this product is not advised to be applied on decks. It is a high gloss varnish, so when it gets wet, there is an excellent chance for the surface to become extra slippery. To avoid accidents on the deck, I decided to apply a matte marine varnish instead.

• Extremely durable
• It does not peel and crack easily.
• Flexible; can be used on different surfaces.
• Made with tung oil
• Thick and pigmented
• Can cover stains and scratches
• It can’t be used on the deck
• Slippery when it gets quite wet

For me, I will still go for this product even though I can’t use it on my deck. It gives some of the best gloss that I have seen, and it is very durable!

What a beautiful product! All I can say is wow! This marine varnish is quite exceptional! This company really is the Old Master of the varnish industry. The sun is known to be a catalyst for the faster aging process of wood and paint, which results in brittle and faded-looking boats.

I am so happy that I have this product, which is perfect for absorbing the sun’s harmful UV rays, so it worked well as my boat’s exterior marine varnish! I love how it can be used above and below the waterline so I could still protect the bottom half of my ship from fading quickly.

Although this product works well as exterior spar varnish, I am in awe because it is also useful as an interior varnish! Because of its satin finish, the deck would not feel slippery even when the area is wet. I love how the safety of all riders is guaranteed because of this varnish!

However, it took me three days to finish the entire application process because the drying time took 5-8 hours per each coat. But even though the process took quite some time, I was not disappointed with the result that I got!

After patiently applying eight coats, I was left with the most marvelously looking boat! It seemed very mysterious; not too shiny, not too matte. Now, my boat has the perfect coating!

• Absorbs the sun’s harmful UV rays
• Perfect as an exterior marine varnish
• It can be used below the waterline.
• Also great for interior portions of the boat
• It prevents boat aging and fading
• Not too shiny, not too matte
• The drying time is 5-8 hours per each coat

Because of this product, I am so glad! I was left with a good-looking and well-protected boat. I could not ask for more!

I am so happy that this product is a water based marine polyurethane varnish. It can be challenging to find a glossy varnish that is water based because most glossy varnishes are oil based. Because of this, I am always on the hunt for a water based product that is a high gloss, and finally, here it is!

I love that this product is exceptionally eco-friendly because it does not contain VOCs or volatile organic compounds, which can be harmful. Varnishes usually release these, and long-term exposure to these chemical compounds can result in long-term health effects.

I am so relieved to finally see a marine varnish that does not negatively affect humans and species that reside in water. I love how this company went the extra mile just to give us a healthier alternative to the usual varnish formula that we get in the market!

Another reason to stan this product is its exceptional clarity! Upon using this, I could immediately say that it produces a very smooth, flexible, and clear varnish. I am so happy because I did not have a hard time applying it on the boat.

I really like how this varnish was able to encourage the improvement of my boat’s woodwork! It did not weirdly interact with the ship, and it actually sank into the wood utterly. This is one of the best features of this product!

Now, let me tell you about its leveling property! This is the smoothest and most even varnish application I have ever experience. I love that it glides on smoothly and allows room for error. You can go over a wet varnish as many times as you want!

• High gloss, even though it is water based.
• Eco-friendly
• It does not produce volatile organic compounds.
• It does not pose harmful health problems.
• Exceptional clarify
• Improves woodwork
• Amazing leveling property
• Allows room for error during application

As a water based varnish, I cannot believe that this is as amazing as it is! If I were you, I would stock up on this product, especially if you have multiple boats!

Indeed, a fantastic product! This marine polyurethane varnish gave my boat an amazingly bright and lively hue. I love how it did not change my boat’s color; it only brightened it up by introducing a nice sheen on top of it!

For this one, I decided to use a bristled paintbrush because it made the application smoother and more even. It went on in a more uniform layer, which makes layering seamless and effortless! Even though it has a thick consistency, it works well with a brush. I love how it did not form any air bubbles!

Because it is quite thick, the drying time is kind of long. I applied it for a total of two days, and on the first day, when the temperature was low in humidity with excellent air circulation, each coat was able to dry for just 5 hours. However, the weather was a little more humid on the second day, and each coat dried for 7 hours.

I love how hard this product is once it is dry! Because of its thick consistency, it was able to cover my boat’s surface better than other marine varnishes. It can resist stains, scratches, and other minor physical damages that roaring waters and sharp rocks can cause. I love how I can be assured that my boat will look its best even when I sail rough waters!

When I started to check how it feels inside the boat, I was taken aback because it did make a huge difference! I thought that the interior had a new coating, but it did not feel slippery at all. I can assure you that this marine grade varnish for wood is very useful in providing a safe surface for passengers!

I am quite disappointed with this because obviously, one of the main reasons why we, boat owners, invest in great marine varnishes is because of its UV protection. Although this product offers a great sheen and exceptional thickness, it, unfortunately, cannot prevent the boat from aging and fading.

• A modified version of polyurethane
• Did not form any air bubbles and streaks
• Thick consistency offers excellent protection.
• Resists stains, scratches, and other minor physical damages
• Not slippery
• It does not have UV protection.
• It can’t protect my boat from aging and fading.

I am very fond of this product. I can see myself using it more in the future, although it will work best as an interior marine varnish!

The marine varnish is for people who are passionate about improving their boats’ appearance. Other than that, it can also be used as a substitute for the typical varnish that is used for daily materials such as doors, windows, chairs, and tables.

Boat Owners

The marine varnish is for boat owners because they take pride in their boats’ beauty and maintenance . Boat owners need to apply marine varnish on their ships because it protects the wood against the rigorous events that take place while sailing.

Marine Artists

Marine artists also need marine varnish because they are responsible for doing the dirty work that most boat owners prefer not to do. They get paid to paint, design, and apply varnish on boats so that the wood is protected and well-maintained.

Varnishing is an essential aspect of carpentry because it strengthens wood. It provides a protective layer between the wood and the outside world, which could pose harmful threats to the wood.

Marine varnish, sometimes referred to as spar varnish, is a term that is quite famous in the boating world. This specific type of varnish is a finish specially designed to protect boats from the harsh conditions they experience during sailing. It is one of the essential materials that a boat owner has in their arsenal of boating essentials.

There are a lot of different options when it comes to purchasing a marine varnish. Here are some of the best features that you might want to consider before buying one:

UV Protection

This is the main reason why marine varnish was specifically made is for it to act as a UV blocker against the sun’s damaging UV rays. As you shop for your next varnish, it is vital to make sure that you are getting one that has the best marine varnish UV protection because it will help to prolong your boat’s life.

Remember that a protected boat will always remain on top of its game. It will not age, fade, and get damaged easily.

High Gloss, Satin, or Matte

There are three different finishes that marine varnish comes in:

It will make your boat appear new and shiny. This variant is best used for the boat’s exterior area because it tends to become too slippery if used inside the ship. Accidents may happen, such as accidental slips, which could result in harmful injuries.

As you can tell, this finish is entirely flat and free of any shine and gloss. This is the best choice for your boat’s interior area because it will provide you and the passengers the perfect surface texture for walking and standing.

This finish is perfect for both exterior and interior portions of your boat. It has a sheen, but it is not too glossy. It is a fusion between a high gloss and a matte, which leads to a perfect finish that is suitable for any boat.

Tinted or Untinted

A tinted marine varnish has the capability of slightly altering the original color of your boat. It will most likely produce a more resonant tone that will complement the color of your boat’s wood. Usually, oil based marine varnishes have tints.

Basically, this form of marine varnish does not have any color to it. If you prefer to maintain your boat’s paint but you want to add some gloss and protection to it, you may opt for this variant. Typically, water based marine varnishes are untinted.

Oil Based Or Water Based

As mentioned above, oil based marine varnishes have a tint to them. It could be amber, golden, or a rich copper tone. As time passes by, rest assured that your boat’s tint will get more prosperous and more profound.

I like this type of marine varnish because it does not try to hide the wood grain of the boat. It actually aims to improve its texture, not cancel it out. It is also essential to take note that oil based marine varnishes are glossier if compared to water based marine varnishes.

Water based

This base has no color at all; it is transparent. It only provides gloss because it does not affect the original color of the boat. However, this has the tendency of flatting out the wood grain of a vessel.

Again, take note that even though water based marine varnishes are still quite glossy, it is still less glossy than oil based marine varnishes.

Marine varnish’s sole purpose is, in simpler terms, to protect the boat from aging. It can block the sun’s UV rays, which can slowly but surely deteriorate the wood’s quality and color.

Most marine varnishes in the market nowadays are effective in protecting the wood against harmful light. This will ensure the boat owner that their boat will maintain its quality for an extended period of time.

Aesthetically Pleasing

The varnish is used to enhance the wood’s appearance. It provides shine and evenness across the entire wood surfaces. It reduces the wood’s porosity by sealing each area; it penetrates the wood without damaging it. It also keeps tiny wood parts in place to avoid woodcut incidents.

Covers Micro Tears, Scratches, and Stains

Marine varnish can also serve as an additional cover over micro-tears, scratches, and stains. Even though your boat has some scratches, rest assured that a few coatings of the best boat varnish will thoroughly cover it up. Also, it is thick enough to resist minor physical damages.

Disadvantages

Slow Drying Time

Some, not all, marine varnishes tend to dry slowly. So instead of getting the job done within a day, you might have to work for 2 to 3 days just to finish all of the needed varnish layers.

Can Contain VOCs

Most marine varnishes nowadays contain Alkyd or Polyurethane synthetic products. Although they provide excellent results for applying and retaining the varnish onto boats, they produce high amounts of VOCs or volatile organic compounds.

VOCs are gases that Alkyd and Polyurethane emit into the air. It is associated with the formation of cancer within the human body. It also has the capacity to interact with other forms of gases, which could result in both short-term and long-term health issues.

Some other health issues that volatile organic compounds pose are the following:

• Irritation of eyes, nose, and throat
• Dizziness and headache
• Memory loss
• Visual impairment
• Sick building syndrome

Clean Before and After Sailing

As a rule of thumb, always clean your boat’s surfaces before and after sailing . Not only will it make sure that your varnish is well-kept and beautiful-looking, but it will also lengthen the life of your boat.

While cleaning, do your best to get rid of all sorts of grime and dirt. Check both the interior and exterior. It is also a smart choice to do a thorough cleaning at least once or every two weeks. Not only will it keep your boat hygienic, but it will also make your boat maintain its best shape.

Apply New Varnish If Needed

Yes, you have fully applied marine varnish on your boat’s surfaces. However, you need to check for the need to reapply every now and then. Keep in mind that it is always better to prevent damage rather than to repair it.

By doing a monthly check-up, your boat’s safety and elegance will always be assured. If you can see certain varnished spots that have thinned down, reapply several marine varnish coats onto that area to avoid the promotion of wood brittleness.

Where can I Buy a Marine Varnish?

There are a lot of different places where you can purchase a marine varnish. Here are some of the most common establishments where you can find the best marine varnish for your boat:

• Hardware stores
• Department stores
• Ship’s stores
• Marine stores

Can a Marine Varnish be used on a Deck?

Yes, you may use a marine varnish to enhance your deck’s beauty and UV protection. But make sure to choose a matte or satin marine varnish so that the deck would be safe to walk on. Avoid using high gloss marine varnishes because they will be too slippery to walk on and may result in unwanted accidents!

Does a Marine Varnish Effectively Waterproof a Wood?

In a way, it does provide a non-porous layer between the wood and the outer area. Think of marine varnish, especially polyurethane marine varnish, as a thin plastic that clings onto the wood. If you put in enough oceanic varnish layers, you will successfully get rid of any porous areas, directly waterproofing the wood.

In a nutshell, every boat owner has to have a little bit of knowledge on marine varnish because it is one of the most effective ways to preserve a boat’s health. With just one session of marine varnish application, their craft will be protected for a long time.

The marine varnish is essential to protect boats from getting older instantly. As much as possible, we have to do our best to take good care of them because, let’s face it; they cost quite a lot! This list of the best marine varnish of 2021 will surely give you some ideas about which varnish to purchase!

Varnishing your yacht is an essential part of its care and maintenance. The benefits are twofold: yacht varnish protects your boat from the elements, while also giving it a beautiful shiny finish. But with so many different yacht and marine varnishes to choose from, it can be difficult to know which one is best for your boat.

In this article, we’ll run through some of the most popular types of yacht varnish on the market to help you choose the right option.

What is Yacht Varnish?

Yacht varnish is an extremely durable solvent-based coating that is designed to protect the wood that yachts are made of and stop it decaying over time. Most varnishes are made up of a penetrating oil, resin and solvent. Although most yacht varnish is applied with a brush, it is possible to buy yacht varnish spray.

Different Types of Yacht Varnish Finish

There are many different types of finish to choose from, so you’ll need to know a little about them to decide which is the best yacht varnish for you.

Yacht Varnish Brands

There are various brands that produce yacht varnish. Here are a couple of the most popular:

Screwfix Yacht Varnish

Screwfix is a retailer in the UK that sells a variety of products, including hardware and building supplies. They may carry different brands and types of yacht varnish. Yacht varnish provides resistance to water, UV rays, and other environmental elements. Yacht varnishes often contain additives to enhance their durability and performance in marine conditions.

Ronseal Yacht Varnish

A durable, long-lasting marine varnish for wood that flexes with the movement of the wood and resists peeling and cracking. This varnish is slightly more pricey than the Screwfix varnish, but gets great reviews. You can buy the Ronseal brand of yacht varnish in B&Q and other retailers.

How to Varnish Your Yacht

Varnishing a yacht is fairly straightforward, if a little time-consuming. First you’ll need to carefully sand down the entire surface that you want to varnish to get it looking smooth. Then use a soft brush to wipe off any excess dust and debris, since you don’t want it getting trapped in the varnish.

Finally, use a paintbrush to coat the yacht with varnish. Leave it to dry for the recommended amount of time on the tin, then apply additional coats as required. Always check the instructions of your varnish type, and if unsure consult with an expert before starting.

Yacht varnish is solvent-based and contains toxic chemicals, which means it should not be used for varnishing animal enclosures (for example, rabbit hutches or reptile enclosures).

• What is yacht varnish used for? Yacht varnish is used for sealing and protecting wood on boats and yachts. It is also commonly used for outdoor items such as wooden doors, window frames or pergolas.
• What type of varnish is yacht varnish? Yacht varnish is a solvent-based outdoor varnish that is extremely durable. It is usually made up of tung oil and polyurethane resin. 
• What is the best varnish to use on a boat? The type of varnish that is best for your boat will depend on the type of wood your boat is made from and the finish you are looking for. Tung oil varnish is a safe bet for most boats, or you may prefer to use a one-part polyurethane varnish for added durability.
• What is the difference between yacht varnish and outdoor varnish? In general, yacht varnish dries quicker and is designed for marine conditions, so it’s likely to be more durable than outdoor varnish. However, yacht varnish is unlikely to have an anti-slip formulation, making it unsuitable for decking around the home.

Best Marine Varnish for Boats

What is Marine Varnish? Marine varnish is a finish coating that protects the outer part of the wood. Specifically, in this instance, it protects the wooden parts of a boat from the sun, rain, wind, sea spray, ultraviolet rays, chemicals, and other extraneous factors. Therefore, a marine varnish must be applied to a boat’s outer wooden parts. Therefore, for one to gain the full advantage of marine varnish, he must choose a good marine varnish product to avoid unnecessary complications that would affect the structure of the boat’s wooden surfaces. In this article will discuss the best marine varnishes to help you make the right choice when purchasing a marine varnish product. 

Some Of The Best Marine Varnishes for Boats Are:

Epifanes Clear Varnish

The “Epifanes clear varnish” is well-rounded when it comes to all the features an exterior finish should have. It is composed of Ultraviolet rays filters like alkyd resins and phenolic that would protect the outer wooden parts properly from the effects of Ultraviolet rays. Due to its components, it is easily absorbed by wooden surfaces, and its effects are long-lasting, which makes it an ideal wood varnish. In other words, it gives off a durable rock solid result. It also has a glossy finish that improves the aesthetic value of any wooden surface. 

Application of the varnish can take days because of the process involved. However, another advantage of the “Epifanes Clear Varnish” is that it takes less time to apply than the typical marine varnish, and more than three methods can be used. In other words, this particular product is very effective when it comes to the longevity and durability of wooden structures. Link to Amazon .

Total Boat Lust Marine Varnish

A remarkable feature of this marine varnish is its high glossy look, improving the aesthetic value of any boat’s wooden surface. Generally, most marine varnishes change the color of the wood it is applied on by either making it a lighter or darker shade of brown, thereby altering the originality of the wood. The “Totalboat Lust Marine Varnish” improves the wood’s original color without taking from the original aesthetic. The varnish makes the original color of the boat bolder and gives it a fresher look. 

Also, because of the varnish’s nature, sandpaper is not needed to remove materials or scratches from the wood surface because the varnish aims to improve the wood’s natural texture. Like the “Epifanes Clear Varnish,” and unlike most marine varnishes, Total Boat Lust Marine Varnish doesn’t take much time to apply because it dries fast. It can also be applied between six to eight coatings which is not difficult compared to other varnishes. A day is sufficient. 

This product is available in two different forms: the matte finish and the high gloss finish. The matte finish improves the natural beauty of the wood, giving it a bolder outlook. In contrast, the high gloss finish improves the brightness of the woodwork. The varnish is also strengthened by UV stabilizers which means that the wooden surface will be protected from Ultra Violet rays from the sun. Link to Amazon .

TotalBoat Gleam Spar Varnish

As the name implies, the “TotalBoat Gleam Spar Varnish” can be applied to almost every wooden part of the boat. It can be used for the exterior and interior parts and even wooden furniture with the boat. An excellent feature of this varnish is its versatility. It is made up of tung oil, resins, and other stabilizers that prevent ultraviolet rays from affecting the wooden structure of the boat. It is highly resistant to sunlight and its effect.

Also, it is a very unique varnish that gives off a warm effect and has a very pleasant smell that lacks harshness when applied. 

It also improves the coloring of the wood by giving it a light amber effect which improves its beauty. In other words, the “TotalBoat Gleam Varnish” makes the wooden part of the boat look and smell nice. Another valuable feature of this varnish is that it is waterproof. The importance of a boat being waterproof cannot be over-emphasized because it improves the lifespan of the boat’s wood (like a wooden deck) and prevents decay etc.

In terms of application, it can be applied in several ways. For instance, it can be applied using a brush, a roller, a spray gun, etc. This varnish comes in two forms: the gloss and satin finish. The gloss finish varnish is the preferred option for the outside wooden part of the boat because of its properties. It gives the boat depth and makes it look more solid when applied. Also, the satin varnish improves the texture of the wood, so it is great for interior woodwork. Link to Amazon .

Pettit Captain’s Varnish

Unlike the other recent varnishes, the “Pettit Captain’s Varnish” is an old brand that has been on the market for over 5(five) decades. The beauty of this product is that the new version is always better than the last. In other words, the “Pettit Captain’s Varnish” is a legendary brand that has been greatly improved over the years. As a result, it is the “experienced boater’s choice”. It has a glossy look that improves the boat’s natural beauty and gives it a bold and deep feature when applied.

It is a very durable varnish that lasts long and has been tested and recommended by boaters for decades. Also, the varnish provides UV protection on the wooden surfaces from UV rays’ effects. Like the “TotalBoat Gleam Varnish,” the Pettite’s varnish can be applied inside and out. In addition, the varnish can protect the boat from harsh weather conditions when applied properly.

As for the properties of the varnish, it is a water-based, marine-grade polyurethane gloss varnish that gives a smooth, elegant effect after it has been applied to any wooden surface of your boat. Another added advantage of this varnish is that it is eco-friendly. Most varnishes affect the environment because of their chemical elements. Also, they can impact the health of the boaters in the long run. However, this varnish is all-natural and eco-friendly, and this feature makes it stand out from the other varnishes.  Link to Amazon .

McCloskey/Valspar Spar Varnish

Which Yacht Varnish Is Best For My Boat?

Yacht varnish is a specialized type of varnish that is often used on boats. It has several advantages over conventional varnish, which is why it is becoming more and more popular among boat owners. In this guide, we will discuss the benefits of yacht varnish. We will also answer some common questions about yacht varnish. So if you are interested in learning more about this topic, keep reading!

Yacht varnish is a type of varnish specifically designed for boats. It is typically made from a tougher resin that can withstand the harsh conditions that boats are exposed to, such as salt water and sunlight. Yacht varnish also often contains UV inhibitors to help protect the wood from fading and other damage caused by exposure to sunlight. Conventional varnishes are not as durable as yacht varnish and will not stand up to the same conditions. This makes them less suitable for use on boats. However, they can still be used for other applications, such as furniture or around the garden.

Which types of varnish to use on my boat?

Marine varnish can be divided into three different types, each with its own perfect uses. Yacht owners choose to use one or all of these types for better performance.

Tung Oil-based varnish 

Is the most popular type among yacht owners who take boat maintenance seriously. International Schooner or Goldspar Boat Varnish are both oil-based varnishes that coats the wood evenly leaving a smooth finish while requiring minimal preparation work before it can be applied. This only requires a couple of coats. Is advisable to lightly sand the surface between coats to achieve the highest quality glossy finish. The smooth, high gloss finish will protect teak parts from water stains and help to maintain their appearance over time! Its UV protection helps prevent mould growth too which is especially important in wetter climates. Oil-based varnish is easy to apply and can be repaired by sanding and re-oiling the wood, meaning it will last longer than other conventional varnishes. It's also easier to apply compared with water-based yacht varnish which requires no sanding or priming before application.

Water-based boat varnish

Often used on marine boats where there is not much exposure to agitation or rubbing, making oil-based varnish too heavy for use. This yacht varnish type tends to leave a thin, powdery residue that needs sanding down after drying but offers better penetration into the wood than its oil counterpart. Polyurethane boat varnish - is much more hard-wearing than oil or water-based yacht varnishes. Stronger than oil-based or water-based yacht varnish, polyurethane yacht varnish tends to dry quickly and offers an ultra-hard surface that is resistant to impact, scratching and denting. This yacht varnish type has a high gloss tough finish so it's best suited for areas of the boat that are exposed to more wear and tear. This type of varnish can also be divided into two categories as one part polyurethane boat varnish and two-part polyurethane varnish.

One Part Polyurethane Varnish

The yacht varnish that is most commonly used for yacht paint jobs. The yacht varnish offers a quick drying time and can be easily re-coated within hours between each coat. It should be noted that due to its rigidity it is not recommended to be used for painting highly flexible wooden areas as it might crack in time leaving the wood exposed to elements. Two-Part Polyurethane Varnish - is the varnish with longer working times, making it easier to apply on larger boats. It's advisable to use only one part polyurethane yacht varnish for smaller projects as two-part yacht varnishes tend to leave an unprofessional finish when applied by hand. This type of varnish is extremely tough and consists of two products mixed together. It offers very good protection from moisture and UV damage but the same as the above this is not suitable for some areas on your yacht (such as spars) and it will crack as the wood moves and will leave the wood exposed to the elements.

Is yacht varnish waterproof?

Yes, yacht varnish is typically waterproof. This makes it a good choice for protecting boats from the elements. It can also help to keep the wood of the boat looking its best for longer.

Does yacht vanishes need a primer?

No, yacht varnish does not typically need primer. However, it is a good idea to test it on a small area of the surface you are going to varnish to make sure it adheres properly. If you do decide to use primer, make sure it is designed for use with yacht varnish.

Does yacht varnish seal wood?

Yes, yacht varnish seals the wood. It forms a protective barrier that helps to keep the wood from damage and keeps it looking its best for longer.

How long does yacht varnish last?

The lifespan of yacht varnish varies depending on the brand and the conditions it is exposed to. However, it typically lasts for several years, anywhere from two to three years before you need to apply a new coat or two. Some varnishes obviously last longer than others depending on the area where they will be applied.

Which is better? Woodstain or yacht varnish?

There is no simple answer to this question as it depends on the specific application and the needs of the user. However, in general, yacht varnish is a better option for protecting wood from the elements and keeping it looking its best. It is also typically more durable than wood stain, which makes it a better choice for boats.

Why is it important to sand between coats?

It is important to sand between coats of yacht varnish because it helps to create a smooth, even surface. This makes the final coat of varnish look its best and helps to protect the wood from damage.

How many coats should I apply?

The number of coats you should apply depends on the specific product you are using and the area you are varnishing. In general, two to three coats are sufficient. However, it is always a good idea to follow the manufacturer's instructions for the best results.

What type of finish can you get?

There are three types of finish on boat varnish: gloss, semigloss, and satin. Each one has its own benefits and drawbacks, so it is important to choose the one that best suits your needs. Gloss finish is the most durable, but it is also the most reflective. This can make it difficult to see in bright sunlight. The semigloss finish is less reflective than gloss, but it is still quite durable. It is a good choice for areas that receive moderate amounts of sunlight. The satin finish is the least reflective and also the least durable. However, it can provide a more natural look to the wood. It is a good choice for areas that do not receive a lot of sunlight.

Can you paint yacht varnish over wood stain?

Yes, you can put yacht varnish over the wood stain. However, it is important to make sure that the stain is fully dry before applying the varnish. Otherwise, you may end up with a sticky mess.

How long does it take for yacht varnish to dry?

The drying time for yacht varnish varies depending on the brand and the conditions it is used in. In general, you can expect it to take anywhere from six to eight hours to fully dry. However, it is always a good idea to read the manufacturer's instructions for the best results.

Can you thin yacht varnish?

Yes, you can thin yacht varnish if it is too thick. However, you should only use a thinner that is specifically designed for use with yacht varnish. Otherwise, you may end up with a poor-quality finish.

What is the best way to remove yacht varnish?

The best way to remove yacht varnish depends on the type of finish you have. If you have a glossy finish, you can use a polishing compound. For a semigloss or satin finish, you can use sandpaper. In general, it is best to remove yacht varnish with a power sander. However, you can also remove it by hand if you are careful.

Can I apply a new coat over the existing varnish?

Yes, you can apply a new coat of varnish over the existing varnish. However, it is important to make sure that the old coat is in good condition. Otherwise, you may not get the desired results.

Does yacht varnish go yellow?

Yacht varnish is designed to keep your boat looking good as new even throughout the season's hottest and coldest temperatures. The UV inhibitors prevent yellowing, which can otherwise occur due to exposure to external factors like sunlight or rainwater on a dock; they also remain slightly soft so that it will not crack when expanding or contracting with changes throughout each year. Liquids such as engine oils may cause blistering if left unprotected by an anti-blister agent like silicone lubricant (which contains graphite).

Is yacht varnish oil or water-based?

Yacht varnish is typically oil-based. This makes it more durable and resistant to fading. However, water-based varnishes are also available. These are less durable but easier to apply.

So which yacht varnish is right for you?

Choosing the right yacht varnish depends on how much time you want to put into maintaining your boat as well as its location. We stock a wide range of varnish suitable for any type of wood on your vessel.

Boats are dynamic vessels that provide comfort, luxury, and possibly income. You spent a lot of effort and money on them. As a boater, your main priority is to ensure that your vessel is in good working order so it can serve your needs.

The woodwork is a crucial component of the boat that demands special attention. If your boat’s woodwork isn’t adequately cared for, it could lead to discomfort and irreversible damage. Losing a boat to something as minor as damage from the sun, rain, or wind can be disheartening.

This article will provide you with all the necessary information to choose the best varnish for your boat. I also provide you with some varnishes that I recommend.

What is a Marine Varnish?

To begin with, a varnish is a protective coating you can use on woodwork. The varnish provides protection against sun, rain, or chemical damage.

Marine varnish is simply a type of varnish meant for watercraft. It is transparent, but sometimes it has yellowish or dark brownish shades. The shades usually come from how the manufacturer made the varnish or the material it is made with.

What is a Marine Varnish Used For?

Marine varnish is very similar to regular varnish. The only difference is that a marine varnish is used on watercraft, whereas normal varnishes are used on other surfaces.

Because boats are always outside and almost always on the sea, it’s a constant risk for sun damage, water, and other harmful elements.

Like I said earlier, the varnish protects against tiny scratches as well as weather-related severe damages. If the woodwork in your boat has no protection or proper maintenance, it dries out, making it vulnerable to potential damages.

Sometimes, these damages can be permanent and could cost a lot of money fixing or replacing the damaged part.

Furthermore, on the other hand, a marine varnish protects the wood and enhances its attractiveness. It makes it gleaming and glossy, giving your boat an elegant appearance. Also, nobody really likes to look at ugly dried wood.

What are Marine Varnishes Made of?

As a science geek, I usually like to know what is inside any product I get and what they do, especially when it has to do with something as big as a boat. So, if you happen to be as curious as I am, then here you go! But if you are not, feel free to skip to the next paragraph of this article.

Fundamentally, there are five main ingredients in marine varnish, and they are:

• Oil – The oil provides a soft, shiny, and natural look to the wood.
• Resin – Resins add a glossy effect to the wood. It also makes the color and grain of the wood shiny, giving it that elegant look.
• Solvent – Solvents serve two purposes. First, they can be used to melt down the resin to be applied to the wood. And secondly, they can also be used to thin the finishes, making them easier to apply.
• Driers – This helps the marine varnish to dry faster.
• Additives – The additives help the marine varnish last longer by protecting it from the sun. It is designed to protect the wood from the harmful effects of sunlight.

Factor to Determine When Choosing a Marine Varnish

In order to find the best marine varnish for your boat, there are a few things you must consider.

Here they are:

How Long Will it Last on the Boat?

As you know, the most important thing about any product is how long it can last. When it comes to marine varnishes, it is essential to understand the durability of the product. This is because the boat is constantly exposed to substances like rain, sun, etc.

Some marine varnishes last much longer when compared to others, and some require special procedures like extra coatings. At the same time, some last up to two to three years before recoats are needed.

So, when buying your marine varnish, I advise you to try to ask your dealer all questions you can think of about the durability of the product so you can make the right decision according to what you want.

How Long Will it Take to Dry ?

The second thing you should consider when looking for a marine varnish is how long it will take to dry.

If you happen to be working on a limited timeframe and need to have your boat completely coated and ready for use in a day or two, then this is a factor you should consider. In this case, you should only look for varnishes that dry much faster. Some dry in a matter of hours.

If you are not in a rush, you don’t have to worry about this so much. But still, look for marine varnishes that can serve your timeframe.

How Easy or Difficult is it to Use ?

I would advise you not to ignore how difficult or easy any product is to use, especially when it comes to marine varnishes. To avoid wasting a lot of money, please find out everything you can about the brands and how to use them. If it is what you can handle, then go for it!

How Glossy is It?

This might sound funny, but yeah, glossiness does matter a lot. Most times, high-glossed varnishes happen to be the best durable because of the thickness. Plus, it also adds to the attractiveness of boats. So, it is safe to say, the glossier the varnish, the better!

Top Ten Marine Varnishes

There are several marine varnishes on the market today. However, I have picked out the top ten products based on the criteria above (durability, drying ease, ease-of-use, and glossiness).

TotalBoat 482869 Lust Marine Varnish

The TotalBoat Lust is the brand’s top product and a top product in the marine varnish industry. Their varnish is extra thick, which provides your boat with maximum protection.

The TotalBoat marine varnish has a U.V. and weather resistance, which makes it the perfect choice for brightwork and more. U.V. means ultraviolet light, means the sun.

The TotalBoat Lust marine varnish is the first one-part marine spar varnish. Usually, when applying varnish on the wood, after each coating dries, you are supposed to scrape the surface with sandpaper so the next coat can stick. However, you don’t need to do that with the TotalBoat Lust because it’s a one-part varnish.

Aside from the safety and convenience features of this product, it does enhance the beauty of the wood. Due to the thickness of this product, it’s able to give your boat an elegant look by adding the shine and glossy effect.

Pros and Cons

The TotalBoat lust marine varnish is an excellent product, but it has a few downsides.

Here we discuss a few pros and cons of the products, which will help you decide if it is something you can handle or not.

The Rust-Oleum marine spar is easy to use as long as you thin it down to 10% to 30%. It dries up quickly when applied to the wood, and there would still be enough to go around.

The radiant result of this varnish is deemed to last. You can apply it with ease, as it can be done through a roller, brush, or spray gun.

There are two choices of this varnish: gloss and satin. The gloss varnish appears so clear and with depth. You should apply 4 to 6 coatings. The more layers, the better. I prefer using satin varnish on interior parts as it’s good at enhancing texture.

Applying this varnish once or twice a year is a part of my boat’s maintenance . Three applications are recommended per day. Recoating can follow in a matter of an hour. The coatings you have done in a day should be given 48 hours to dry up completely.

This product may be commonly used for woodwork, furniture, cabinet, paneling accessories, and doors. But it is included in many marine spar varnish reviews. Do you want to know the reason why it can be a great varnish on wooden parts of your boat?

It’s a clear gloss formula that bears special oils. With these components, this varnish can expand and contract with the wooden surfaces. The changes in weather, temperature, and season won’t be a hindrance anymore.

The clear gloss finish won’t be prone to graying and fading due to the UV blockers. Once applied to the wood, it creates a protective barrier against moisture and rain. With the aforementioned characteristics, it is an undeniably essential part of any water vessel maintenance.

I use it for both the interior and exterior wooden sections of my boat. It’s like a custom as I do the application every year. I don’t need to look for a better product for I’m satisfied with this varnish.

I’m surprised that it dries quicker than what I expect from an oil-based formula. The result makes the wood a bit dark, but I’m not complaining. I do rather love the effects as it enhances the color and appearance.

• Used on many things (woodwork, furniture, cabinet, paneling accessories, doors, etc.)
• The formula contains special oils
• Can adapt to the changes in weather and temperature, blocks rain and moisture
• Gives a clear, glossy finish
• Has UV blockers so it’s prone to graying and fading
• Makes the wood appear a bit darker

It is recommended as a protective coating for exterior wooden surfaces because of its abilities. The layers of finish from this product are long-lasting, and I find its durability outstanding.

It’s spar urethane water-based as it can deflect water and is highly resistant to mold, mildew, scratches, and possible damage from UV rays and harsh weather. You may need to do some cleaning up to keep the gloss at its optimal appearance. Use soap and water to keep it neat.

Nonetheless, I also use it on the inside of my boat. I don’t want this area to be deprived of the amazing effects of this coating. It’s convenient and comfortable at the same time to apply it in the interiors as it has low odor. So I don’t get suffocated with some undesirable fumes.

When I went over the exterior wood finishes comparison, it dried quickly as it only needed thirty minutes. I love how easy it is to apply for its absolutely stunning effects. Just make sure you don’t do it when the temperature is over 90 degrees Fahrenheit.

Applying it when the temperature is high would make it dry before you achieve an even coat. A whitish tint will be the final result. I do re-coating after two hours, and it’s done four times as per the manufacturer’s recommendation. A quart of this product can cover 87 square feet.

I must admit I like matte, but I won’t turn into this wood finish if it’s not giving my boat the striking effect. The satin sheen that it gives is so nice, and it gives a soft matte attractiveness.

This finish can also be proud of its durable outcome as it has UV protection for wood, teak , and other hardwoods. Aside from having it on my boat, you can see its marks in my house as I love wood pieces more than concrete. You can rely on it to protect the wooden surface from outdoor elements.

It’s a one-component matte finish that has tung oil and phenolic-modified alkyd resin. Imperfections in the wood are concealed when applied. I think it’s because of the minute porosity properties. Due to this factor, sanding is not necessary between coatings.

The matte finish has a rubbed look effect, which I like the most. I read on marine varnishes reviews that it’s challenging to apply this substance that is more liquid. When applying with a brush, you have to be quick and put it evenly.

Knowing some techniques would make steps a lot better. I used mineral spirits to thin it out. I added 25% of it for the first coating and just 10% for the second one. I find it dead flat on the first coating, but I’m amazed on the second try as it showcases the perfect matte finish.

• Gives satin sheen and a soft matte finish

You just can’t underestimate old school, just like this varnish from Pettit. It’s still among the most favorite marine polyurethane varnishes, and it gives the same result for 55 years. I don’t know if it sounds funny, but patronizing this product has been handed from my grandfather to me. My boat teak as well as pieces of furniture benefit from its gloss finish.

What makes me and my family use it most of the time is its durable finish, just like how I keep using my boat teak all year round without looking worn out. It’s like an inch thick that seems to project a nice-looking 3D surface.

Its toughness is also tested on the mahogany door at home. This door is exposed to direct sunlight. It’s in its second year now, and I think I need to wait for another two before reapplying.

Thus, it is considered as a spar varnish to exterior door. The credit goes to the UV protectors which prolongs its life. It’s the ultimate shield from the harshest environment.

All these wonderful things happen because it is a water-based, marine grade polyurethane gloss varnish. It’s rich and obviously, of high quality. You can also use it on interiors too aside from brightwork exteriors. The clear and smooth finish reveals the natural beauty of the wood.

The texture of this varnish is like wet honey. When you use a new paintbrush for application, try to apply the varnish first on a spare surface. It should be done to avoid loose hair.

If your color preference is the same as mine, this is the Epifanes marine varnish for you. I always achieve a flawless finish from this product. I think it’s because of its contents which are tung oil, phenolic, and alkyd resin. I’m in awe of its extremely glossy finish.

The most important part to me is that the varnish creates a durable finish. I find this product trustworthy for protecting the wooden surface of my boat. Maximum UV blocking is included in its formula, and that’s what I need when summer comes as I often go out with my boat this season.

The finish is also water and salty air resistant. It’s also not prone to damage that can be caused by bad weather conditions. It gives the boat a nice appearance, and it keeps the beautiful surface as time goes by. So I feel secure that my boat can keep the shiny surface for a long time.

The clear satin finish is just awesome. It won’t only look good on the boat’s wood trim above the water, but also with outdoor wooden furniture, planters, lamp posts, interior window frames, and mills.

The durability is outstanding. It can preserve the good state of these things. I recommend using it on the front door, which receives a lot of sun rays. You will benefit a lot from this varnish if you live in a hot area.

A good bristle brush or a foam brush can be used for the application. The consistency is not similar to honey, so you can lay it out easily. It will be dry to the touch in a matter of four to six hours. Three or four coatings are needed. A light sanding can be done in between.

The other name for a marine varnish is spar varnish. It has a formula that is specially crafted for marine exposure. Tung oil, phenolic, and alkyd resin are the usual components present in it. It is deemed as an excellent varnish that forms a finishing suitable for the wooden surface.

It was made for the pole of wood found in sailing ships in the past. Changes are inevitable until it’s the scope of use includes all the wooden areas of the boat. It’s done as a part of maintenance and for beautification purposes nowadays.

The result from the marine varnish is sturdy. It can withstand bad weather conditions, water, and salty air. Its coverage is great on an unpainted wooden surface. People in every corner of the world would call it water-resistant exterior varnish.

Using a marine varnish, you are creating protection not only with your boat but also for furniture and projects with wooden materials. What’s under the covered deck can be in wooden form. So it means that it is exposed to different weather and harsh exterior elements.

To cite an example, UV rays are not too friendly towards the wood. Thus, chalking and cracking occur, and they destroy this material. So a marine varnish is an essential thing to your boat or other vessels. Doors displayed to the sun’s heat all the time can also be protected by the varnish.

When it comes to application, the general recommendation has three coatings. The first one should be thinned with 50% mineral spirits to give way to diffusion. The next step would need two full strength, and sanding may be required between coatings.

The classic varnish is extracted from a resin tree. The thicker one that is present these days is a combination of tung oil, alkyds, and phenolic resins. Furniture pieces were the ones that are receiving the gloss, but later on, boat masts started to take the coating too.

Masts bend with the wind, so varnish moves with it rather than cracking. Thus, a single part consists of a tung oil base, which is also called spar varnish. It is dissolved in solvents, and it’s being hardened right away after application. The first coating should be hardened first before the succeeding coating.

You have to give every coating adequate time as the solvent that’s under the layer will tend to evaporate.

Polyurethane

This oil-based varnish is composed of one part polyurethane. Chemicals that are similar to epoxy are in their content. Its usage is applied to covering clear epoxy resin. One way to make layers quicker is to apply epoxy on wood in just a matter of three or four coats of polyutherane with UV protection.

Polyutherane can either be water or oil-based. The advantage of water-based polyutherane is that you can easily clean the crystal clear finish. On the other hand, oil-based lasts longer, and it gives a bit of yellow color. It’s up to you if you prefer color enhancement.

Both of the bases should be hardened first before applying the next coat.

Exterior Varnish

It is formulated for outside utilization, and it specializes in providing UV protection. This varnish is microporous, which means that the wood can breathe. Therefore, mildew and mold don’t have the chance to assemble and rot the wood.

Yacht or Spar Varnish

It is mainly formulated for boats to counter the persistence of water. This solution is suitable for outside timber.

Acrylic Varnish

It is considered non-toxic and dries quickly. It’s quite flexible as it can be used on the inside and outside areas. Ultraviolet-light protection is its best feature. It can also be seen on other kinds of surfaces aside from wood.

The finish that acrylic varnish gives is so clear, but then it doesn’t penetrate the wood. There’s no complication when using it, so it’s user friendly. However, it would be difficult to spread the formula evenly.

Two-Part Varnish

Mixing is what is done with the two-part varnish. The base and the hardener are bought separately and then combined. Resistance to abrasion and durability are the highlights of its features.

Two-part varnish dries quickly as the moisture and air react to it. It shows that it lessens the weight of the job. The coating becomes very hard, too; thus, you can expect a long life from it. So you can go easy on maintenance.

The main reason for varnish application is to give your dear boat or any water vessel optimum protection. Investing in the top-tier marine varnish is a wise move. A boat is much more expensive than a can of varnish.

Choosing the ideal product, tool, equipment, and marine varnish can prolong the good condition of your boat. With marine varnish, you are given assurance that protection against damages is provided. It does an excellent job of safeguarding wooden surfaces.

A marine varnish can impede the accumulation of mildew and mold as well as water penetration and inevitable wear and tear. It does a wonderful job of enhancing the looks of your vessel. Your boat may even look like an expensive one.

The drawbacks of applying marine varnish exemplify the saying – ‘no pain, no gain’. But it doesn’t necessarily mean that you’ll be hurt. What it takes is patience, and it requires more time. You can’t get it done in just a snap of a finger.

The drawbacks would start with slow drying, so a lot of time is needed. Thus, dust built-up can also happen. Some boat owners will just be surprised about the incompatibility of the lacquer or water-based varnish. Issues may arise during stripping or repairing.

These are the things that you have to check when deciding what marine varnish to buy:

Most of the marine varnish is at a high price. So make sure that you pay for something worthwhile. You should have the initiative to check important information about the product. So you can avoid financial strains if you get the ideal product.

Cleaning Up with Ease

Even though you are careful, it can’t be avoided that there is some amount of varnish drops. With a formula that is easy to clean, you will find it effortless to eliminate the spill.

Easy Application

Applying the varnish can be challenging, especially for newbies on woodwork. If you are one of them, better use a product that is easy peasy for you to handle. Refer to the manufacturer’s recommendation of the best method of application.

The finish should serve you and your boat for a decent period. Who would want to go back and forth for repairs? Thus, it hinders you from spending money just to make corrections.

Time of Drying and Curing

Minimizing the drying time makes varnishing convenient for you. In this matter, you have to estimate the time that you will spend on your project. So you can manage your schedule.

Although marine varnish is consumable, you still need to be conscious of how you carefully take care of it. In this part, you have to be knowledgeable about the part by reading the label. Take note of precautions for everyone’s safety.

It should be away from the reach of children. Bear in mind that spar varnish is combustible. Don’t place it near open flames, hot surfaces, sparks, and of course, direct heat. Smoking beside it is hazardous to your lungs. It’s like giving yourself ailments as you breathe horrid substances.

When you apply varnish on your boat, you have to be in a well-ventilated area. You have to be outdoors. Protective gear is also necessary, such as gloves, a shield for the eyes and face, and a respirator.

Who makes the top-rated marine varnish?

TotalBoat marine varnish and spar varnish, RustOleum marine varnish or spar, Minwax spar urethane, Pettit varnish, System Three coating, McCloskey varnish, and Epifanes matte finish or Epiphanes marine varnish.

What is the difference between spar varnish and regular varnish?

Spar varnish is designed for outdoor use due to the consideration of different weather and temperature. Its formulation is different from a regular varnish. Humidity can cause the wood to expand and contract. When you use a typical varnish, it will easily crack and get damaged under this circumstance.

Aside from the protection that is provided by spar varnish, flexibility to UV rays is one of its features. So it extends the surface’s life, and it means durability. That’s why spar varnish is deemed to surpass the rigorous condition of marine life.

The difference between spar varnish and regular starts with the oil ratio. The former has more percentage of oil, which will soften the solution. It results in a more flexible finish. Meanwhile, the latter tends to crack when the wood expands or contracts.

Is marine varnish waterproof?

Yes, it is, but you have to take note of the components as each of them specifically works well with a certain kind of wood. For instance, some waterproofing methods are suitable for exterior or interior finish. Some are great for light or dark grained wood.

Make sure the components are compatible with your purpose of varnishing. If you wish to have an attractive and hand-rubbed finish, tung oil and linseed are the right components. It will be the first step that you need to take.

The second part is sealing the wood with lacquer and polyurethane. Of course, the final part is simultaneously waterproofing the wood. Use a stain-sealant combo for this process.

Is marine varnish better than polyurethane?

You can’t exactly say that varnish is better than polyurethane as each of them serves different purposes. It will depend on your purpose and preference too. The varnish turns into an amber or faint yellow shade. Its appearance is similar to the result of oil-based polyurethane.

The varnish is usually applied on water-exposed boats, outdoor decks, or deck chairs. What makes it suitable for these things are its water resistance ability and high solid content.

The formula of varnish has low toxicity, so it’s safe to utilize on exterior doors. The variant called marine varnish or spar offers flexibility and protection against UV rays. So most woodworkers are fond of it. They would apply it to softwoods that are known to flex under extreme conditions.

When it comes to varnish application, you must do it correctly. You also have to see to it that you give it enough time to completely dry. If you fail to do these things, the finish will likely crack, peel, or form some bubbles.

The wood can be susceptible to damages from the surroundings if you don’t do the necessary procedures properly. Several layers should be applied to achieve the optimal result. Give each layer six hours to dry so you can get the photo-finish result.

In the case of polyutherane, its texture can be compared to a liquid plastic. This attribute is based on its content, which can be resin or pure synthetic plastic. The milky appearance turns into a clear coat in just a single or two coatings.

Polyutherane is abrasion-proof, and it can correct a scratch. It is available in water or oil base and something in between called sheen. DIYers like it a lot as there are options like satin or glossy.

Since the content or base can be different, you should know the right designation of use. The water-based polyutherane gives off a revitalizing finish as it maintains the natural color of the wood. Perhaps, for its strength is the low toxicity level, you can clean its coating with soap and water.

The oil-based counterpart is usually seen on hardwood floors. It is capable of providing protection that is more robust than the water-based. So it’s not likely to just give up on UV damage and heat. You can rely on it so that it won’t crack.

The oil-based type is also heat tolerant. Its outcome enhances the wooden tone as it transforms into an amber tone.

To conclude, it can’t be claimed that varnish is better than polyutherane or the other way around. It all depends on the purpose of application or coating.

How long does marine spar varnish last?

The lifespan of marine spar varnish will depend on the environment. Exposure to direct sunlight can reduce its longevity. Rub spots because of hard service require fixing, which leads to the need to apply some coatings or layers.

Recoating should be done in cases of scaling. The affected area is sanded first to reveal the wood for recoating. A good six to eight coatings would remain to look awesome for 4 to 8 years.

You may have done every step properly, so coatings formed well on the wood. Maintenance has a big part too in prolonging the life of spar varnish. Keep it clean all the time.

Where can I buy it?

You don’t have to look high and low for marine varnish. You can get it from a home depot or any of your local hardware stores. You can also opt for online shops but make sure you access a legit website that provides a quality product.

There’s an array of brands both online and offline. When you check online, you can have more ideas about the product. So you can decide which one will work for you best.

What are some tips when applying marine varnish?

Applying outdoors is best done in the morning during the time that the dew has dried. Doing it in the late afternoon or the evening would lead to improper drying and loss of gloss.

Direct sunlight is not also good as it will make the varnish dry quickly. It’s not a recommended method. When you’re varnishing the interior sections, air ventilation is acceptable for drying.

It can’t be avoided that varnish may fall off at the wood edges due to the less film thickness. So what you need to do is to apply extra coatings. The first two coatings need to be thinned by 20% or 25%.

Sanding in between coats can be an extra job, but it is sometimes needed to achieve a flawless finish. It is a chance for you to correct mistakes like drips and runs. Make sure the previous coating is completely dried before you proceed to the next one.

When it comes to the brush that you need for marine varnish, you can try badger brushes. The most important thing that you have to pay attention to is the cleaning and maintenance of this tool. Always start the application with a damp, clean brush.

Think about the best marine varnish that can serve your purpose and application well. The formulation varies to suit the needs and preferences of users. So, it’s the buyer’s responsibility to check the components of a specific marine varnish they’re eyeing to buy. After you read this review, you’ll surely know what’s best for your boat or water vessel.

I am passionate about water sports and technical fields, so combining both makes me interested in making contents about boat accessories. With my partner, we went on many trips and sports games together, which led us to think about how we can spread our joys and passions to many people.

What’s The Best Varnish For Your Yacht?

Written by Abigail Meadow - Tuesday, June 01, 2021

Varnishing your yacht is essential to protect it from the elements and preserve its longevity. As wood is a natural product, it’ll break down and become damaged when exposed to moisture, general pollution, and UV rays. Varnish creates a barrier against all of these things, gives your yacht a beautiful finish and makes it easier to clean.

The best way to prevent damage to your boat is to touch up any breakage in the wood as soon as you notice it. Doing this will prevent water from soaking into the wood. Generally, it’s good to varnish your yacht every one to two years.

However, varnishing isn't a simple task, as there’s a large selection of boat varnishes to choose from. Gaining an understanding of the qualities of different types of varnish is essential so you can choose the ideal one for your boat.

Here, we reveal which varnish is best suited to your yacht.

1. How to varnish

Wood must be sanded before finishing – slow and steady is the way to go with sanding. Don’t dig into lower grooves, as it’s important to create even layers when sanding. Otherwise, when the varnish sits on top, it won’t have the professional finish you’re looking for.

When you’re finished sanding, wipe any excess dust with a super soft brush, as you don’t want to varnish over small sharp wood. Some woods, such as teak, are rich in natural oils, so it’s a good idea to wipe the wood with a solvent such as acetone after the final round of sanding. This dissolves the surface oils and helps with finish adhesion.

Once you’ve finished sanding, use a paintbrush and coat the wood in the varnish. It’s important to be precise with varnish and coat every part of the wood thoroughly.

2. Choosing the right finish

Some woods such as teak, cedar, and oak can be left unfinished. These woods are decay-resistant, but adding a varnish finishing enhances its appearance, so most owners still choose to use varnish.

Tropical hardwoods such as cocobolo and lignum vitae are difficult to finish with varnish, as oil-based varnishes won't dry properly when placed on top. If you have a teak deck, it's best to leave it bare, but you should clean the surface regularly with liquid soap or a specific teak deck cleaner. Don't use a stiff or wire brush or rub with the grain when you clean, as this is too harsh. Avoid the temptation to pressure wash your yacht, as doing this will damage and weaken the wood.

The advantage of unfinished wood is that you’ll never have to refinish it; if installed properly, it can last years. Most boat owners prefer the sheen of an oil or film finish, even though this is unnecessary.

3. Tung Oil Varnish

Tung oil boat varnish is what some yacht owners refer to as the classic varnish. It’s referred to in this way because if you’re unsure of what your boat needs, this is a classic, middle of the road, safe bet.

The base and main ingredient of tung varnish is a natural oil, mixed with other things such as solvents, resins, and UV protectors. This type of varnish is flexible and can protect the wood from water, staining, and heat damage.

Over time, however, this type of varnish will crack off the surface, at which point you’ll need to recover the boat in varnish again.

4. One-part polyurethane varnish

Today, most varnishes use blends of synthetic resins such as polyurethane, phenolic, or alkyd polyester. Polyurethane is also known as urethane and is more durable than the other resins.

One-part polyurethane varnish produces just as good a finished result as tung oil and offers the same amount of protection, but is much more durable. Due to its strength, this type of varnish is often used for interior wood flooring.

Due to its rigidity, one-part polyurethane shouldn’t be used on highly flexible areas such as spars, as it can crack and be rendered useless.

5. Two-part polyurethane boat varnish

This varnish consists of two products that have to be mixed. Such as an epoxy resin – listed below, and polyurethane varnish.

This type of varnish is extremely tough, offers very good protection from moisture and UV damage, and helps protect areas prone to damage.

Two-component polyurethane coatings offer better results than single-component ones. In fact, they can guarantee greater resistance to abrasion and chemical agents, high durability, and higher conservation of the coating film.

Again, due to its hardness, two-part polyurethane boat varnish shouldn’t be used on highly flexible woo. That’s because it could crack, leaving room for water to damage the wood.

6. Epoxy resin

Epoxy resin can be used to coat timber, but it generally has poor resistance to UV light. Usually, another varnish tends to be applied over the top, as boats are exposed to a high level of UV rays, especially in the summer months.

At this point, we should advise you to beware of inexpensive yacht varnish sold in various DIY shops . Lower prices are usually an indication of extended drying times or poor long-term performance when on the water.

Questions for Investigators Trying to Unravel Mystery of Luxury Yacht’s Sinking

The investigators searching for answers about the shipwreck, leaving seven dead, face questions about extreme weather and possible human error or problems with the yacht itself.

• Share full article

By Alan Yuhas

More than 180 feet long, with a mast towering about 240 feet and a keel that could be lowered for greater stability, the Bayesian luxury yacht did not, in the eyes of its maker, have the vulnerabilities of a ship that would easily sink.

“It drives me insane,” Giovanni Costantino, the chief executive of the Italian Sea Group, which in 2022 bought the company that made the ship, said after its wreck last week. “Following all the proper procedures, that boat is unsinkable.”

But the $40 million sailing yacht sank within minutes and with fatal results: seven dead, including the British technology billionaire Michael Lynch, his teenage daughter, four of Mr. Lynch’s friends and a member of the crew. Fifteen people, including the captain, escaped on a lifeboat.

Mr. Lynch had invited family, friends and part of his legal team on a cruise in the Mediterranean to celebrate his acquittal in June of fraud charges tied to the sale of his company to the tech giant Hewlett-Packard.

The Italian authorities have opened a manslaughter investigation, searching for answers from the survivors, the manufacturer and the wreck itself. They face a range of questions and possible factors.

An ‘earthquake’ in the sky?

When the Bayesian sank around 4 a.m. on Aug. 19, the waters in its area, about half a mile off the Sicilian port of Porticello, were transformed by an extremely sudden and violent storm, according to fishermen, a captain in the area and meteorologists.

But what kind of storm is still a mystery, compounded by the fact that a sailing schooner anchored nearby did not have its own disaster. Also unclear is whether the crew was aware that the Italian authorities had issued general warnings about bad weather the night before.

Karsten Börner, the captain of the nearby passenger ship, said he’d had to steady his ship during “really violent” winds . During the storm, he said, the Bayesian seemed to disappear behind his ship.

Severe lightning and strong gusts were registered by the Italian Air Force’s Center for Aerospace Meteorology and Climatology, according to Attilio Di Diodato, its director. “It was very intense and brief in duration,” he said.

The yacht, he said, had most likely been hit by a fierce downburst — a blast of powerful wind surging down during a thunderstorm. His agency put out rough-sea warnings the previous evening, alerting sailors about possible storms.

Locals have said the winds “felt like an earthquake.” A fisherman in Porticello said that he had seen a flare go off in the early-morning hours. His brother ventured to the site once the weather had calmed about 20 minutes later, he said, finding only floating cushions.

The Italian authorities have so far declined to say whether investigators had seen any structural damage to the hull or other parts of the ship.

Open hatches or doors?

The boat executive, Mr. Costantino, has argued that the Bayesian was an extremely safe vessel that could list even to 75 degrees without capsizing. His company, the Italian Sea Group, in 2022 bought the yacht’s manufacturer, Perini Navi, which launched the ship in 2008.

Mr. Costantino said that if some of the hatches on the side and in the stern, or some of the deck doors, had been open, the boat could have taken on water and sunk. Standard procedure in such storms, he said, would be to switch on the engine, lift the anchor and turn the boat into the wind, lowering the keel for extra stability, closing doors and gathering the guests in the main hall inside the deck.

At a news conference on Saturday, almost a week after the sinking, investigators said the yacht had sunk at an angle , with its stern — where the heavy engine was — having gone down first. The wreck was found lying on its right side at the bottom of a bay, about 165 feet deep.

12 guests occupied the yacht’s six cabins. There were also 10 crew members.

Open hatches, doors and cabin windows could have let in water during a storm, according to the manufacturer.

Water pouring into open hatches or doors could have contributed to the sinking, experts say, but that on its own may not account for the speed at which such a large boat vanished underwater.

Asked about the hatches at the news conference, the authorities declined to comment on whether they had been found open at the wreck.

The authorities have also not specified whether the boat had been anchored, whether it was under power at the time or whether its sails had been unfurled.

A retracted keel?

The Bayesian had a keel — the fin-like structure beneath a boat that can help stabilize it — that could be retracted or extended, according to its manufacturer. On some yachts, keels can be raised to let the large vessel dock in shallower water, and extended downward to help keep a boat level.

But like the hatches, the status of the keel alone may not explain why a large ship sank with such precipitous speed. Investigators have not disclosed what divers may have seen at the wreck, aside from saying divers had faced obstacles like furnishings and electrical wiring in tight quarters. Officials want to raise the wreck to better examine it, a process that may take weeks.

Human error?

Ambrogio Cartosio, the prosecutor in charge of the case, said at the news conference that it was “plausible” crimes had been committed, but that investigators had not zeroed in on any potential suspects.

“There could be responsibilities of the captain only,” he said. “There could be responsibilities of the whole crew. There could be responsibilities of the boat makers. Or there could be responsibilities of those who were in charge of surveilling the boat.”

It remains unclear what kind of emergency training or preparation took place before the disaster, or what kind of coordination there was during it. So far, none of the surviving crew members have made a public statement about what happened the night the ship sank.

Prosecutors said they want to ask more questions of the captain and crew, who have been in a Sicilian hotel with other survivors. They said that neither alcohol nor drug tests had been performed on crew members, and that they have been allowed to leave Italy.

Prosecutors also said they were also investigating why the captain, an experienced sailor, left the sinking boat while some passengers were still on board.

Besides possible manslaughter charges, the authorities are investigating the possibility of a negligently caused shipwreck.

The bodies of five passengers were found in one cabin, on the left side of the yacht, the authorities said. The five were most likely trying to flee to the higher side of the boat and were probably sleeping when the boat started to sink, they said.

Topside-Paint Endurance Test 3-Year Checkup

Two-part lpus rate highest for durability and gloss retention..

Our topside-paint test panels have endured three full years of 24/7 exposure to the elements, and the time has come for their final evaluation. Testers have annually scrutinized the paint swatches and rated the topside coatings on gloss retention, flow out, scratch resistance, and anti-oxidation ability. In this final round of evaluating, we will also compare the panel results with the products real-world performances aboard our test boats.

Our goal from the start of this test was to take a variety of promising topside coatings and apply them to boats in our test fleet-sailboats, dinghies, and other craft-and set up an in-situ test to validate or contradict our panel testing. These field tests have put paint systems through more realistic punishment in a true working environment. And the comparison between real world usage and static testing helped us validate both a wide range of the paints tested and the testing protocol itself. (See Field Test Findings” on right)

Testers reported on the application of these paints in the August 2008 issue and rated their performance in the November 2009 and February 2011 issues. Now, at the three-year mark, testers can offer some interesting observations about specific paints and paint types.

How We Tested

For the long-term evaluations panel test, we applied two coats of each paint to carefully prepped sections of fiberglass panels. The panels endured identical weathering, and the swatches were washed with a mild soap before inspection. All ratings are relative to the field.

Gloss-retention testing included taking reflected light readings, in bright daylight, with a spot meter and reflected light meter; results were averaged. To test for oxidation buildup, testers placed a new cotton/polyester piece of cloth on a rotary disk and moved it slowly over each coating surface for 20 seconds, then noted any residue on the cloth.

To determine the hardness of each coating, testers used Gradcos pencil hardness test method: A roller device holding a pencil at a given angle was pushed across the surface of the coating; by using pencil leads of varying hardness, the coating was eventually scratched, and testers noted the hardness of lead required. We rated each performance on a 1-5 scale with 5 being the hardest. Tests were repeated five times.

To test for adhesion, testers used a scalpel to cut crosshatches through small sections of paint, then placed a piece of masking tape over the crosshatched surface, rubbed it and pulled it off. Paint pulling away from the surface detracted from the rating. All of the paints passed the adhesion test.

For the one-year report (PS, November 2009 ), testers evaluated abrasion resistance using a Scotchbrite scuff pad and 3 pounds of pressure; this test was conducted only on white paints. They used drops of dark tea (mimicking tannic acid, the culprit behind most waterline stains) to evaluate stain resistance.

Test Panel Findings

All of the topside paints that weve been monitoring fall into four categories: conventional enamel, modified enamels, two-part coatings, and water-based paints for marine use. Our tests found that when it comes to ease of application, the one-part products stole the show. But the highest marks for gloss, hardness, and durability went to the two-part polyurethane coatings.

Our intentional use of the term coating stems from the way these long-chain, polymer-linking paints behave. In essence, they are more of a catalyzed resin than conventional enamel. The latter loses solvent through evaporation during its curing process, while the former goes through a molecular crosslinking process that leads to both extra hardness and a wet-looking, high gloss. One thing we did notice in this field of super performers was that they come with some tradeoffs.

For example, industry leader Awlgrip (an Azko Nobel company) is the manufacturer of coating systems marketed for professional use only. Because their two lines of paints are available to the general public at West Marine and other retail chandleries, we included them in the test. These are not DIY coatings for the inexperienced, but the skilled and practiced DIYer-those already familiar with fiberglass repairs, applying epoxy primers, and fairing a surface, and who know what sanding to perfection really means-may be ready to handle professional-grade products like Awlgrip.

The top-rated Awlgrip behaves much like the other two-part products in our paint reviews, and it delivers the very best results. The companys top-coat bifurcation gives users two different products and approaches to two-part painting, and its worth a closer look. The makers traditional two-part, high-solids, polyester-based linear polyurethane (LPU) coating is named Awlgrip and its acrylic, modified two-part polyurethane topcoat is Awlcraft. The latter is easier to handle and allows a user to fix flaws in the finish or spot repair damage that occurs at a later date. Sags, hangs, or a fly doing the backstroke just after the final coat is applied don’t result in as critical a failure as they do with Awlgrip. With Awlcraft, wet-sanding and touching up is not as much of a Michelangelo-level skill as it is with Awlgrip because Awlcraft is a bit softer and can be rubbed out and polished back to maximum gloss in the same manner automotive paints are handled. However, as with all softer acrylic-based LPUs, theres a drop in abrasion resistance when compared with polyester-based LPU paints like Awlgrip.

Between top-rated, top-priced Awlgrip and much softer, brush-friendly one-part enamels resides an interesting array of chemical innovation. Traditional enamels like those made by Z-Spar, Kirbys, and Sherwin-Williams delivered good initial gloss but most deteriorated over the three-year test run. The good news is that none suffered adhesion loss or excessive oxidation, and an open can of alkyd enamel doesn’t have the harsh chemical odor that two-parts have.

Interlux and Epifanes urethane modified enamels outpaced old-style paints and nudged ahead of Pettits EasyPoxy. West Marines Sea Gloss Pro also delivered great results. CrystaLacs Crabcoat was the only water-based product in our test, and from the start, gloss was not its strong suit. But Crabcoat does offer good adhesion, durability, and an attractive semi-gloss, and for those working inside or in tight confines, theres the bonus of a low VOC level. However, when it comes to comparing one- and two-part paints, its important to note that theres a significant performance gap between them.

After three years of testing, its become clear that two-part paints are in a league all their own. All two-part coatings we evaluated had more shine and better adhesion at the three-year point than any of the single-can options. That said, there was a grouping of top single-part urethane modified enamels that surprised us with their durability and, to a lesser extent, their shine.

Interluxs Brightside and Epifanes Mono-urethane are case in point, and in our third-year panel evaluation, they earned high marks as all-around paints when it came to ease of application and durability. Perhaps the best test of their tenacity was how well they held up on the cockpit sole of Technical Editor Ralph Naranjos Ericson 41. (See Field Test Results on right) These paints have endured 3 years of sailing travails plus the onslaught of icy winters and boiling hot summers. The gloss has diminished some, but their adhesive quality as nonskid paints and waterway topcoats has been impressive.

When all was said and done, theres no question that the professional approach to a two-part paint makeover yields the best-looking results. However, there are a few shortcuts that do work and a few that should be avoided. One-part urethane modified enamels like Brightside, Epifanes Mono-urethane, and Pettits Easypoxy deliver handling convenience and a surprisingly long-lasting finish. Boat owners who have mastered the handling challenges of a two-part LPU sprayed finish can get close to the like new look of a professional paint job. But keep in mind that these coatings contain aggressive solvents and other unfriendly chemicals. Covering up and wearing an appropriate respirator and eye protection are part of the process.

We were glad to see that results from our three-year panel testing showed a strong correlation to our field test findings. The winners in both test groups paralleled paints highlighted in previous years. One of the biggest surprises, however, was that traditional enamels held their own, retaining good adhesion, despite losses in gloss retention. On the panels, all of the paint products remained well adhered, but a few failures in the field could be linked to shortcuts in preparation. We demonstrated that those looking to lessen the chances of ending up with flaking and peeling paint should consider using an epoxy primer and above all, follow manufacturer surface prep guidelines as closely as possible.

This weekend I saw my first example of a “vinyl wrap” as a topside application, on a 50’ Fontaine Pajot (sp?) catamaran. Almost overnight the boat Was transformed from an ordinary, dated, white hulled cat, to a like-new boat in a striking gray finish. How does this system compare to other topside finishes like traditional gel coat and two part finishes?

Hello D.N.; thanks for the update on the topside paints but one question. I used EZpoxy polyurethane on my 1967 Morgan 24 this year and noted they offer the Performance Enhancer to increase hardness and durability. I used it as they advised and am happy with it thus far. The results are noticeably harder and cure faster and (for those who desire it) there is a higher gloss… Why have i heard nothing about the combination in various reviews including yours? It is an easy to work and forgiving topcoat…why no notice?

i am wondering about using an oil based exterior finish that is NOT a marine product… obviously these are much cheaper… any testing on this?

I have restored, modified, and repainted a few boats in my amature days. Full disclosure I am a former marine mechanic and have taught technologies for 20 years. Brightsides has been an overall disappointment to me. In 4 attempts at repainting my Bluenose 24, (my brother in law is a rough landing skipper) I only had the gloss come up once. The other three times the paint kicked too early or just cured dull. In putting an epoxy bottom coat on my Shark 24, with Pettit epoxy, that claims to cure even down to 5 celsius, the paint started kicking on the roller leaving a bumpy mess like a teen’s complexion. Pettit replaced the product and after exhaustive grinding off the previous mess, it happened again. Pettit is off my list forever. Epifanes has been my go to choice for my trawler yacht, a Mainship Mk1. It has been the best experience of them all. Using a roll and tip method, the brush strokes did not level out leaving noticeable lines up close. I contacted Epifanes Canada and they now recommend just rolling, and they are right. Just roll it on and it’s great. Yes the mono urethanes are softer, but they are so much more user friendly when rolling on. A factor when some drydock locations would not allow spraying without building a full enclosure. After my first season, a green dockhand caused a minor scratch with improper line handling. I called Epifanes and they advised just tape of a trapezoid shape around the scratch and repaint it. You will have to get real close to see the tape line. BAM! it worked just like they said. I now do not fear docking scratches as I know I can successfully with little fuss repair them during drydock times, or even afloat if need be. I have no investment in any of these products. I am Epifanes sold. Awlgrip is too fussy for a DIY boatyard job. Unless you want to fork out big bucks, accept the 4 foot test. If it looks great 4 feet away, be happy.

Total Boat on deck. A forty years old non skid started to erode. Sanding was almost impossible: it grinned all sand paper and the majority of wheels. I decided to deal extensively and degrease. And coat of Total primer ( same color as the original ) was applied. A second coat after two days did not offer nay adhesion advantage, using the metal comb scratch and peel testing method. It was followed by one coat of Total Boat Wet Edge (white) mixed with 33% Total Boat Non Skid ( Light grey to match the primer ). I added 50% of Interlux flattening agent. The result is very satisfying. I liked the non-skid : its material does not settle as much as other manufacturers like Petit. This system will be easy to maintain if necessary. It took 5 hours per coat on a 36ft deck, trapping included. The temperature was above 65F. and the humidity was low. There was high wind that accelerated the drying process. I’d be interested to read Practical Sailor writing on Total Boat products. This system was tested against test panels of Petit and Interlux. I did not see any major difference in adhesion nor ease of application.

Before tackling ANY large painting project, paint a few 1-to 2-foot panels, playing with rolling, tipping, and specifically, the working temperature and amount of thinner.

Never push the low temperatures or high humidity. Follow the instructions or the odds will incline against you. I avoid paint projects both spring and fall in cold climates–the weather is just not dependable enough. Instead, I target that part of the summer when the wind stinks anyway and sail in the off-season.

I’ve always been able to get the finish I wanted. I pick the weather, dial in the thinner, buy the best rollers and brushes, and prep ahead of time so that I can easily finish in one push.

As for non-marine finishes, Rustoleum Gloss Protective Enamel is dependable for little projects like brackets and backing plates. I always keep a can of white handy–exact color matching is not vital on small things. It takes fewer coats than yacht finishes and seem to hold up about as well. Every hardware store has it.
