TotalBoat Clear Penetrating Epoxy Wood Sealer Stabilizer for Rot Repair and Restoration (1.5 Gallon, Traditional)

Reliable and Professional-Grade SealerThis epoxy works exactly as described—solidifies compromised wood and restores strength and integrity to aging structures. The 2:1 mix ratio is straightforward, and the product applies smoothly with minimal odor. Once cured, it creates a strong, stable surface ready for additional coatings or repairs. Ideal for boat projects or any serious restoration work. Excellent quality and performance.

I bought this to use on a section of RV floor that would have been super difficult and extremely destructive to replace. I've used other epoxies thinned with recommended ingredients as penetrating epoxy for rot or water damage on wood before, so knew to both follow directions and use "penetrating' holes (whatever they are called) to get best saturation. This product worked extremely well without needing to thin at all.Material used on was 3/4" OSB underlayment used in the RV industry. Small area to repair (roughly 1'x1').Process: Removed flooring, drilled holes at 3/4" intervals with a 3/16" drill bit and stop set to 1/2", extending holes an additional 4-5" on sides of severely damaged underlayment. Allowed to dry out for 2 days of 90+ temperature. Did test pour on 2" square on day 2, allowed to set overnight. This was satisfactory the next day (and penetrated thoroughly). Did full pour on day 3, temperature around 84 at start. Poured, worked in with rubber squeegee and chip brush. Left windows and screen door open for 24 hours, checked the next morning. Process was successful, and penetration was even better than hoped. Scraped and sanded some bumps because I didn't vacuum sawdust from drilling adequately and replaced flooring after 48 hours. We left the windows open for 3 days after (RV is under cover, so no concerns about rain getting in)The floor is sturdy now. There was never significant smell or concern about VOCs. I did wear a NIOSH mask and use a vacuum while sanding. I wore gloves at all times while using the uncured product, and while sanding. If I had used a larger bit for my penetrating holes, I would have put a second coat on to thoroughly fill the holes, but with a small bit I didn't need to do that. If this were to be visible instead of a structural repair under the vinyl flooring, I would have sanded thoroughly and put a thinned skim coat on, then some sort of UV protectant like Polyurethane, paint, or whatever.Hope this helps others :).

I used this on a badly weathered outdoor wooden dining set. I set all the chairs upside down, sanded all the surfaces, and coated the bottoms of the feet so that they wouldn't wick up water. I also filled numerous cracks using disposable syringes also purchased on Amazon. This stuff flows very easily and you might have to do some masking to prevent it from flowing out of cracks. It soaks into the wood very easily, so I'm confident the chair feet won't rot away. Then I sanded all the areas where the epoxy leaked out before treating all the wood with a sealer/oil, also from Total Boat. All in all, it was a lot of work, but the set looks like beautiful furniture again instead of driftwood. I'd say it was worth the effort and I gave the set a new lease on life.Plan your work. Be sure to have everything ready before you mix the epoxy. You only have about 10 - 15 minutes to work with it, so mix small batches to avoid waste.

*Consider my 5 stars with a disclaimer that I've never used any other purpose built penetrating epoxy*Use - I'm restoring a 30yr old camper where the manufacturer had a few leak prone spots and used OSB sheating for the sub floor. In a few spots the OSB had water damage making it slightly soft but not what I would call serious dry rot. I cut out the really bad spots and patched with plywood, and looked for a product to restore the strength of the OSB in soft spots that weren't rotted away yet. I ended up finding this no VOC low viscosity epoxy on Amazon and decided it was worth a shot. I drilled 1/8" holes 2/3rds of the way through the OSB and spaced the holes about 3" apart. I bought disposable injectors and used them to inject this epoxy cut 33% with denatured alcohol into the OSB in a small section of my floor. After curing for about 48hrs at 45*F the subfloor was ROCK HARD, and the product had easily penetrated the areas between the drilled holes and cured into a hardened mass throughout the wood. I'm now 100% confident that this area of the OSB could be exposed to any leak and the steel frame beneath it would rust away before the OSB loses strength. I'm ordering more and drilling holes ALL THE WAY AROUND THE PERIMETER. I'm considering getting a filling agent and using it to level and seal the entire OSB surface. For the time and effort expended and the weight added to my trailer, there was no better way to make this repair and I couldn't find a better no VOC epoxy for the money. I've never personally worked with fiberglass or epoxy construction, but I have a chemical engineering degree and access to alot of expensive products unattainable to an average consumer so it takes alot for something to impress me like this. I think this is actually the first time I've been driven to write an Amazon review.Pros - Easy to mix 2:1 ratio- long enough pot life to load and reload a syringe with epoxy multiple times- Low enough viscosity out of the bottle to inject into 1/8" holes drilled into the OSB for better penetration- Contains NO VOCs!!- Able to be cut with the solvent of your choice to further reduce viscosity and increase penetration and pot life- Used in cold temperatures and still achieved impressive resultsCons - None that I observed
