TotalBoat Penetrating Epoxy Resin

First things first, find and seal all water leaks! If that hasn't been done, it's a wasted weeks process. I followed the instructions to the T. This is a commercial product, not really a consumer product. I used to use this vendor as an MSC Industrial Sourcing Buyer for various different Marine products, so I was pleasantly surprised to find out where it was coming from. Don't be intimidated by this product but proper mixing, thinning and application are key to this giving you a professional result! I perforated the extremely soft if not soggy flooring as noted inn the instructions. Not wanting to remove any more substrate and make obvious repair-reference-points, I chose to us my knife of an awl to make holes that would swell closed and also create fibers to bond together. 😉 After 4 heavy coats applied in multiple directions, thinned with a proper commercial acetone (not nail polosh remover) as noted, I had full substrate penetration, so it was physically dripping out of the front of the trailer. Once I was done, I was able to install the right length screws and snug the diamond plate in tightly against the floor seam again. If you have had to put diamond plate on your trailers front radius, you know how hard it is to draw that metal in and you understand how relevant it is that this structural, 2-part epoxy works that well. I'm not sure it's going to cure all of your soft deck problems but $50 well spent to potentially save yourself $4000 on a noticeable repair that will ultimately hurt your resale value. Our floor was otherwise completely delaminated wood chips. Now its as hard as Kevlar! Not really but it's no longer soft partical board, unsealed from water saturation. It's not solid and impervious! If you're relatively mechanical and you understand how to properly mix, thin and apply part A and Part B epoxies and mix them properly by ratio with the cups provided, understand open life, skin cured and full cure, you'll have a good sturdy floor that's probably better than it was when the trailer was originally built. I've done a lot of technical assistance with adhesives and applications for some huge organizations and I'm super impressed at this epoxies finished result!

*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 results Cons - None that I observed

Reliable and Professional-Grade Sealer This 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.
