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

On a back splash, yes. And you'd probably never experience any problems
but I would recommend 1/4" backer over the 3/8" ply would be better.
