Epoxy question

Anybody use garage floor epoxy paint to seal a replaced transom? Or is it inferior to stuff like gluvit epoxy?

I restored a wood kayak about a year ago. Sanded the whole thing down and painted it with the garage floor epoxy. It did not take well to the wood, lasted a couple months before started peeling off.

That is my only experience with the stuff. Maybe others have had better experience and can chime in. But i think epoxy resin is a much better way to go for the marine use.

Garage floor paints aren't exactly the best Epoxies out there, they start with a low cost epoxy and reduce it with solvent in hopes that it will soak in and level. The problem is adding solvent to any type of resin will weaken it, sometimes a great deal.

The other issue is epoxies aren't very UV resistant, so they tend to breakdown quicker than other products when used outdoors, epoxy parts should be painted for good weathering.

And for people that say epoxy doesn't have much of an odor, I've used garage floor epoxy at my house, the smell was so bad I had to set up fans to blow fresh air in for two days. This probably had more to do with the solvents used in the formula, but it was still very strong.

Re: Epoxy question

I'll agree with Ondavr about the smell. I've used commercial grade epoxy to coat hardwood flooring in a food prep area in a restaurant ( required by OSHA ) and it was one of the few finishes that I have to wear a respirator for no matter what. Polyurethane is nothing compared to it.

There are different levels of epoxy quality...just use the garbage that comes in the two tiny separate tubes that cost about a buck and do a repair with it....it's junk.

Its not all it claims to be, epoxy with a great deal of low cost solvent at a high price is what you're buying. (IMO)

Re: Epoxy question

Ok, so its not a good choice then. How about polyurethane? Is it also inferior?

Re: Epoxy question

Poly resin will work just fine, but you have to use matt with it. The poly resin on it's own holds no strength and will crack and not be very good as a sealant.

A good epoxy resin on it's own can be used to seal the wood. It holds up a lot better when there is no matt involved.
