I am going to put 4" x 4" ceramic wall tile in my kitchen. Currently there is 3/8" plywood underneath the current covering (I don't know what you call it, but it is 1/4" glossy cover with fake 4" patterns so that it looks like tile). I was thinking of removing the covering and then possibly putting tile over the plywood. Alternatively, I could put cement backerboard over the plywood. Should I go the backerboard route, or, is it possible to tile over the plywood directly??
Thanks, Al Kondo
