Topic tags/keywords: epifanes penetrating epoxy sealer marine varnish

I’m restoring an oak storm door…taking it down to fresh oak, and sanding to 220.

Then, I’m considering Smith’s Penetrating Epoxy Sealer, followed by Epifane’s Marine Varnish. I’ve read that the Epifane’s should be diluted for the first several coats (1st – 50% – then down to 20% by the 5th coat).

Am I on the right track?

Thanks.

Generally you thin initial coats to aid penetration Since you’re already using a sealer, it might not have a big impact. If you can do a test board it would be helpful. It doesn’t even need to be white oak, just some hardwood.

Those are good product choices for sure. I’ve used the System Three S-1 two-part epoxy sealer with their marine varnish and was pleased with the result. I didn’t thin the varnish at all.

Why the epoxy? The varnish will seal the wood just as good, And the epoxy has to have UV protection anyway. I see no advantage to slathering epoxy on the wood.

Good choice in varnish brand!

It’s my understanding that the epoxy provides the best “primer” so the varnish will adhere better. As Rich says above, he used System 3 epoxy followed by their marine varnish…

I just want the best result. Anybody else have first-hand experience to share?

You’re right. When people hear epoxy, they think of epoxy resin. A penetrating epoxy sealer is a different animal. I think you’re on the right track.

Sorry, varnish will not seal the wood as well as S1 sealer! Not even close!
I’m not familiar with the Smith’s epoxy mentioned but have many years experience with S1 and would recommend it highly, even if some soft rot is present. The stuff is amazing.

I’m with Paul on the S1 Sealer penetrating epoxy by SystemThree products. it may take a little searching to find it in your area or can be purchased from several online sources. (not available in some parts of the USA). Smith’s CPES is certainly a comparable product.
I used Smith’s Sealer several years ago on some wooden boat seats for someone else (at their request) but I never followed up on the project. of course, any clear coat such as varnish is a maintenance item. it requires refresher coatings every so often to provide the protection it was designed for. Epifanes requires a minimum of 5 initial coats to be effective. and you are correct about the dilution ratio for the first coats.

I have years of experience in boats and have never used a primer of any kind under varnish. Just a filler stain on mahogany. Never had a problem with it sealing the wood either.

I have used varnish on my skin on frame kayaks to deal the fabric and it keeps the water outside just fine.
