I have a ceramic floor laid with Thinset over a glued and screwed 1.5" plywood base ( original plywood floor plus 3/4" plywood) . My question is: How do I remove the ceramic tiles to lay a new wood floor? Can I just break up the tiles and save the subfloor? Or would this destroy the plywood subfloor? I'd like to end up with the subfloor being in good enough shape to lay the new wood floor. Any ideas would be much appreciated. Thanks. Alan in Md.
