## Overview

TotalBoat Wood Sealer is a premium one-part marine-grade sanding sealer and pre-varnish primer designed to create a smooth, UV-protected foundation on all types of bare wood. It penetrates deeply to fill wood grain, prevents cracking and peeling, dries fast allowing recoats in just 2 hours without sanding, and enhances the durability and appearance of your varnish finish. Ideal for both interior and exterior use, it covers 60-100 sq ft per quart and pairs perfectly with TotalBoat’s marine varnishes for a professional, long-lasting finish.

## Description

The best way to start any varnish job is to make sure you apply the varnish to a strong foundation on bare wood that’s sealed, smooth, and UV stable. TotalBoat Wood Sealer pre-varnish primer is designed specifically for this purpose. It provides a solid, level foundation for build coats of varnish, promotes good adhesion, and ensures your varnish finish looks better and lasts longer. It’s no secret that bare wood soaks up varnish like a sponge, with the first coat or two disappearing beneath the surface, sealing wood pores and filling the grain. To keep your expensive 1-part varnish from doing this vanishing act, your first varnishing act should be to apply 2-3 coats of TotalBoat Wood Sealer varnish primer - it lets you apply your 1-part varnish without thinning first, so more varnish is available for the finish coats. This economical, one-part pre-varnish marine wood sealer penetrates deeply to seal and prime all types of bare wood — even plywood and oily woods like teak. It also provides maximum UV protection that extends into the wood fibers to prevent cracking and checking.This clear amber wood sealer emphasizes the wood grain and natural color, and won’t muddle the color of marine filler stains applied to bare wood. Just be sure the stain is completely dry before applying Wood Sealer, and test on a small area for compatibility. Apply 2-3 coats of Wood Sealer without sanding between coats, then allow 24 hours drying time before applying varnish. 1-Part marine varnishes like TotalBoat Lust or Gleam 2.0 can be applied over it without thinning first, and without sanding between coats. You won’t waste varnish and you’ll finish much faster. TotalBoat Wood Sealer is compatible with all 1-part varnish products.Compare to Interlux Interprime Wood Sealer Clear 1026 and Pettit 2018 EZ Wood Sealer (formerly Old Salem). All TotalBoat products provide great value and great results. 100% made in the USA.

Review: Love the product - So far we love this product. We used on an oak floor in bed of 1971 Elcamino. I am now trying on my window ledges that nothing appears to work very well on. 1 year later and they still look good.
Review: Total boat sealer - This stuff really works. Used it to seal two cedar projects (bar top and picnic table) before the final coat of spar. Used with Gleam or Lust (total boat spar products) it provides an amazing smooth finish. You can apply all the coats an hour apart so you don’t have to sand in between which saves a ton of time. Goes on well with a brush and evens itself out. I will be using more of this in the future.

## Questions & Answers

**Q: Can this be used under water?**
A: Hey there, Thank you for reaching out. It technically can be used below the waterline but it's not recommended if the boat will see > 24 hours of submersion at a time

**Q: The label says it is "uv stable", what does that mean?  does it provide uv protection?**
A: Yes.  Based on the description from Jamestown this is thinned varnish.  Varnish has good UV protection but nothing last forever in the sun which is why varnish requires another couple coats every year.  This is meant for the first couple of coats in about an 8 coat varnish job.  Least that is how I use it.  Your option is to thin your own or I have enough varnishing from bare wood that I bought this for convenience for the first couple coats then following with in my case Lust varnish also from Jamestown.  I really like the Lust since I can overcoat again in about an hour versus a day for the other varnishes I had been using.  Good luck!

**Q: Can total boat epoxy be used over the top of this?**
A: I would not put epoxy over any sealer. ......

**Q: Is it a oil base water sealant or a stain coloring?  What are the ingredients?**
A: It is oil based and delivers a relatively clear coat that fills the wood  grain quickly in preparation for varnish. However, you can add a solid stain directly to the sealer to get the “color” you desire.

### ⭐⭐⭐⭐⭐ Great for outdoor furniture!
*by A***. on August 28, 2025*

It worked great for our project. We got an old patio table that needed some work and this sealer/varnish worked pretty well. The picture shows the table after the sealer was applied and you can see the previous state on the unfinished chairs.
