another coating ???

ok, here's something else I thought of. was in my local lumber/hardwood store I stumbled across an epoxy that is used on garage floors. has anyone used this or is it even a possiblity? I'm wanting to start my walls but still figuring out the epoxy. may break down and buy the raka brand this week. but was looking for something to use for a base coat for the floor under the black goo. can a person use the fiberglass resin or the floor epoxy with cloth to make plywood joints?
thanks, Brian
