Must I seal plywood sub-floor before laying peel-stick Tile?
I have just had a craft room built into the attic space over my garage. I plan to use peel-and-stick 12x12 tile for the flooring. The subfloor is 3/4" plywood that is smooth and clean. I've been told by a non-professional that I must either seal or paint the plywood before putting the tile down. Is this necessary?
