The goal of restoring a wooden boat, building a piece of wood furniture, or creating a wooden work of art is to make the wood itself look great, and make sure it stays that way for as long as possible – regardless of the type of wood, and whether it’s indoors or out. Especially if it’s outdoors, and the varnish finish will be exposed to sun, salt, and harsh weather.
Make 1-part varnish finishes look better and last longer by coating new or bare wood with TotalBoat Wood Sealer first. It seals the wood fibers and fills the grain to smooth out the surface, removing highs and lows so varnish can be applied to a uniformly level surface, without thinning first.
TotalBoat Wood Sealer has a light amber color that enhances the natural beauty of bare wood. If the wood is stained, marine wood stains typically only fill the wood grain and change the color, but don’t seal the wood. So you still need to apply a sealer before finishing. TotalBoat Wood Sealer can seal in the color of stained wood without muddling, just be sure the stained surface is completely dry before applying the sealer, and do a small test first to ensure compatibility.
Seals all types of wood effectively
Plywood is used in so many projects, from building decks to building docks. It’s very porous and is infamous for checking – those long, thin cracks running lengthwise in the wood grain. They’re caused because wood starts drying on the outside first. This creates tension, which can spawn lengthwise splits on the surface of a board, either on the flat face, the end, or internally. Plywood must be sealed before being varnished or painted to prevent checking and delamination of any finish coating.
Sealing also primes the wood surface, which has two benefits. First, it prevents the finish coats of varnish or paint from sinking into the wood, which prevents you from paying more because you’d have to use more product. Second, this thin varnish primer also bonds to the wood and creates a level foundation for finish coats of varnish to bond to, so they don’t lift in large sections later. Keep in mind that because plywood is so porous, it may require 3 coats of TotalBoat Wood Sealer.
In addition, oily hardwoods like teak and mahogany also need to be sealed to prevent their natural oils from lifting varnish or paint coatings. After properly preparing new or bare wood to remove any oil, grease, dust, or dirt, apply 2 coats of TotalBoat Wood Sealer to seal and level oily woods.
Easier than using thinned varnish for sealer coats
The viscosity of varnish is such that it doesn’t penetrate wood grain easily. For that reason, varnish is usually thinned for the first couple of coats, and needs to be sanded between coats. On the other hand, TotalBoat Wood Sealer’s viscosity penetrates and seals wood more readily than thinned varnish, and does not require sanding between coats. It also dries faster than thinned varnish, so you won’t need to wait as long to start building finish coats.
What’s more, the final coat of TotalBoat Wood Sealer is actually easier and faster to sand than thinned varnish, and because it dries more quickly, you’ll be ready to apply your finish coats of varnish sooner – which can save you a full project day.
Wood Sealer works and dries faster than other clear marine wood sealers — and it’s UV-stable, too
TotalBoat Wood Sealer is definitely not a pain in the arm like other clear marine wood sealers, because you don’t have to sand between coats. It has a viscosity that flows more easily into wood grain, and it dries faster, too, so recoating can happen in less than half the time. It also contains UV blockers that protect all the way down to the wood, which other marine sealers don’t do. Better still, with its longer open time, it won’t skin over and glob up in the can like other clear marine wood sealers do.
Makes for a great finish, but it’s not a finish coating
Use it with either of the TotalBoat 1-part varnishes Lust Marine Spar Varnish or Gleam 2.0 Spar Varnish, which don’t require sanding between coats, either. Together, TotalBoat Marine Wood Sealer and any TotalBoat 1-part varnish gives you a clear, level, beautiful finish in less time — every time.

FREQUENTLY ASKED QUESTIONS
-
What kinds of wood can this be used on?
Wood Sealer Varnish Primer works on all types of new or bare wood, including plywood and oily woods like teak and mahogany. -
Can the Marine Wood Sealer be used over oil-based stains?
Yes, it should be fine to apply over an oil-based stain. We always recommend testing in an inconspicuous spot.Make sure the stain is completely dry before applying Wood Sealer. -
Why should stained wood be sealed before varnishing?
Wood stains typically only fill the wood grain and change the color, but don’t seal the wood. So you still need to apply a sealer before finishing. TotalBoat Wood Sealer can seal in the color of stained wood without muddling, just be sure the stained surface is completely dry before applying sealer, and do a small test first to ensure compatibility. -
Does this varnish primer dry clear, or is it a stain?
Wood Sealer is not a wood stain, and will dry to a clear, glossy finish. Because it dries clear, it won’t change the color of the varnish on top of it or the wood beneath it. -
Does Wood Sealer provide UV protection?
Yes, it does contain UV protection, unlike most wood sealers, but it has lower solids content than varnish and is not intended to be used as a UV-resistant finish on its own. It must be topcoated with a proper varnish for extended durability. -
Can Marine Wood Sealer Varnish Primer be used as a finish?
Wood Sealer is not a finish coating and should be overcoated with 1-part varnish or 1-part paints to provide depth, higher gloss, and more complete UV protection. Do not apply 2-part varnishes, 2-part polyurethane paints, or 2-part epoxies over TotalBoat Wood Sealer. -
Can TotalBoat Wood Sealer be used below the waterline?
No. It is for interior and exterior use above the waterline. -
Should it be thinned for easier application?
When varnishing, the first coat or two are often thinned with solvents to seal wood and create an even base for the finish. Wood Sealer essentially eliminates the need for this, and its lower solids content means it already flows markedly better than unthinned varnish. Thinning is not necessary, but it can be done using TotalBoat Special Brushing Thinner 100 for brush/roll applications, and TotalBoat Spray Thinner 101 for spray applications. -
How many coats do I need to apply?
Apply 2-3 coats of Wood Sealer (3 on porous woods) before applying varnish. -
How long do I need to wait before recoating?
You will be able to recoat in about 2 hours at temperatures above 72°F. It does not need to be sanded between coats. -
How long does varnish primer take to dry?
It depends on the temperature. The minimum overcoat time is 1 hour at 80°F, 3 hours at 65°F, or 8 hours at 50°F. The maximum overcoat window (without sanding) is 48 hours. The minimum time before overcoating with varnish is 24 hours.
