Sealing plywood for floor replacement
Don't know a lot about sealing plywood for my floor replacement. I keep reading about sealing the edges of the plywood. What would happen if I sealed the edges, top, bottom, all over? I've seen SOB with the bottom side completely sealed, since they don't have a belly pan for protection. Also, wooden boats are completely sealed on the outside, maybe both sides, I'm not sure??? Is the issue cost or does sealing the whole sheet of plywood cause some other problems? Any experienced knowledge would be greatly appreciated.
