TotalBoat Wood Sealer Varnish Primer

TotalBoat Wood Sealer fills and seals wood grain to create a level surface for more consistent finishes. This clear wood conditioner prevents varnish from being absorbed into the wood, so finish coats build up faster. Use it to seal plywood and oily woods like teak to prevent finish cracking and checking.

Unlike other marine wood sealers, it features UV-inhibiting filters so finishes are protected right down to the wood. It's fast-drying formula doesn't require sanding between coats. TotalBoat Wood Sealer is compatible with all 1 part varnishes.

Available in a Quart kit that includes 2 quart-size paint pots, 2 wooden stir sticks, 2 2" foam brushes, & a pair of latex gloves.

NOTE: TotalBoat Wood Sealer is not a finish coating and should be overcoated with 1-part varnish 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.


Surface Preparation

Bare wood should be clean, dry, and free of grease, oil, or other contaminants. Sand the surface with 220-grit sandpaper in the direction of the grain until completely smooth. Use a vacuum to remove any sanding residue, wipe the surface clean with a lint-free rag dampened with TotalBoat Dewaxer & Surface Prep, and follow immediately by wiping with a clean, dry, lint-free rag.


Before use, stir well—do not shake. TotalBoat Wood Sealer can be brushed, rolled, or sprayed. Apply 2-3 coats, as directed. Oil hardwoods like teak should require only 2 coats, while plywood or porous wood may require 3 coats.

Thinning should not be required, but if desired, use TotalBoat Special Brushing Thinner 100 for brushing/rolling applications, and xylene for spray applications.

The minimum overcoat time between coats of TotalBoat Wood Sealer is 2 hours at temperatures above 72°F, and 4 hours below 72°F.

Up to 24 hours, TotalBoat Wood Sealer does not need to be sanded between coats. If the maximum overcoat window was missed, sand lightly in the direction of the grain with 320-grit sandpaper, remove any residue with a clean, lint-free rag dampened with mineral spirits, then allow to dry before applying.

If TotalBoat Wood Sealer will be overcoated with varnish, allow the final coat of TotalBoat Wood Sealer to dry for 24 hours, then apply the desired varnish as directed.


Do not attempt to apply TotalBoat Wood Sealer in conditions where humidity is over 90%, or when the substrate, air, or coating temperature is cooler than 50°F or warmer than 90°F. Do not apply when dew or rain may affect the quality of the finish before the coating dries fully.

Sealed my pine door so well


I sealed my front door soft pine wood so that I can apply without blotching. I am very happy with the results. I still left some layer of old sunburn in it to add character.

I will be buying more of this product.


I bought this product to use on very old reclaimed Oak. It looked good but I couldn't get the smoothness I wanted so I tried it on some other woods I work with Maple great, Hickory outstanding, Plywood great and Walnut great. I will be buying more.

Early, but I like it so far


I've only used this twice so far, but I like the very quick drying, and that it has UV blockers built in. I have a suspicion that this is just thinned down Lust varnish, or something similar, but who cares it allows you to seal your wood in three coats on the same day, wait 24 hours, sand, and start applying varnish.

Great dealer and primer


Three coats as a sealer before Lust. Looks so good I cut back on varnish coats, but it is thin and runs easily, you have to be careful.


Melbourne FL


I would buy this product again.


Excellent sealer.

I would buy this product again.


Easy to apply. Two coats sealed Marine Ply well, so varnish went on nice and looked great.




Super Sealer


I purchased this sealer for a Sapele exterior door project. Absolutely delighted at the medium-low volume solids, warm light maple syrup color tone that's quite subtle, and gloss to bring out the depth of the wood grain. It sands and powders quite nicely. Absolutely delighted with the way it flows, and yet dries much quicker than some other varnishes. Could not be happier with the result.


Racine, WI


Works, but probably just poly mixed with thinner/penetrol


Honestly I was expecting more. It's extremely thin, feels like polyurethane mixed with thinner and a drop of penetrol at a higher price. I could have made it myself cheaper. For a beginner this would be a good product.The foam brushes and single plastic glove - for a quart of sealer - seems kind of silly.
