Penetrating epoxy.

In the video, they are restoring a weather checked dinghy seat but, it would work as well on new wood that may be exposed to the weather.

And, I’m wondering if it could be used on a bar or counter top. Certainly useful on any project where you’d want a super durable finish.

You can also use a standard 24hr. cure epoxy in a vacuum bag to create an infused board that would have the same properties. As for a bar or counter top, I suspect that given the viscosity it would take many, many coats to achieve the desired thickness for either.

Hi Gene. Thanks for the video. I have never heard of the penetrating epoxy. When I built a hovercraft i made the mistake to use red oak trim across the top. One season of water splashing on it and it turned black just like the wood in the video. What I used was West System epoxy that I coated the whole boat with.Iit usually penetrates 1/32 into the wood but if you thin it with a bit of acetone, it penetrates deeper . It protected the wood just fine for 10 years with no other coating on it.

I have use thinner for epoxy that allowed it to soak in better. Dries a lot slower though.

Monte, did you use a slow set (24hr.) epoxy mixed with thinner or a quick set (5 – 15min.)? I’m wondering if I took my go to 5min. stuff and mixed it with thinner what the resulting open time would be?

I’ve used Industrial Formulators (now available from System Three) S1 Sealer for years for this sort of thing. With no added thinners it penetrates about anywhere diesel will go. It is a product no other manufacturer had for a very long time. You can harden small rotted areas, seal oily woods to make them retain paint or varnish, seal plywood water tanks, ........ the list goes on. One of the best products around.
It would be interesting to see a comparison of the two. I suspect S1 penetrates better but I noticed the “no VOC’s” tag on the can. I’m afraid I can’t say that for good old S1.
