I am in the process of putting down a hardwood floor and a softwood floor (sinker pine). I need a clear coat that is stronger than regular polyurethane. Is there something out there like that? A friend told me he used an epoxy type coat.
From contributor A:
I have had some measure of success by thinning West System with about ten percent lacquer. They recommend acetone, but since we are not looking for a strong glue joint, I find the lacquer sands much better. It will require a second coat not thinned. The only problem I can see is that epoxy will not hold up to sunlight. You may be able to put a UV inhibiter in the top coats of urethane. I have tried to dissuade several people from using softwoods and they installed it anyway and were sorry later.
