Product Details

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.

Info & Guides

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.


APPLICATION AND USE

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.

Application

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.

WARNING!

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.

I used this as a base coat sealer after staining and under Total Boat Lust Varnish. Works great and very forgiving. Dries fast for easy re-coat. It colors the wood a little but not objectionable.

I like this product

I used when refinishing my garage doors, which are vertical grain Douglas Fir. I stripped the old polyurethane finish and used this as the first coats to a new finish. I really like that no sanding is required between coats.

This is good stuff
By Do John from Bremerton

Verified Purchase

Over the winter I had some spots that moisture got in under my varnish. I scraped the area , did a little sanding, and applied the primer sealer in those areas. Put some varnish over the top and it is hard to tell that it had been repaired.

Bottom Line Yes, I would recommend to a friend

Test in an inconspicuous area before using.
By Tim from Rochester, NY

Verified Purchase

Used this on teak toe rails before varnishing with Lust. It dried quickly and I was able to put on two coats in an afternoon. It is very thin and runny - be very careful of drips! It also darkened the wood more than I expected. One area I had to scrape off and re-do because minor discoloration was exaggerated by the sealer. Test before using!

Bottom Line Yes, I would recommend to a friend

Review
By ??? from Lincoln, NE

My post from sailboat owners.com forum: I recently used Total Boat Wood Sealer Varnish Primer on solid teak that had been sanded down to bare wood. Applied 3 coats using an HVLP gun with 1.4 tip, un-thinned. Laid down beautifully with no sanding, less than an hour between coats. Dried with a really hard finish.

Bottom Line Yes, I would recommend to a friend

Used primer on raw wood. Applied two coats with a light sanding after the first coat. Finished with Gleam varnish. No sanding needed between varnish coats. I am very happy with the Primer and the Varnish.

Bottom Line Yes, I would recommend to a friend
