Ceramic tile over wood underlayment.

Other common types include cementboard or tile backer used under ceramic or stone tile foam underlayment used under laminate and engineered wood floating floors and rosin paper used under solid hardwood flooring. It is a good idea to put half inch plywood underlay to strengthen the floor before using modified thin set to put the tile directly on wood. Ceramic tile over wood structural panel floors wood structural panels have been used successfully under ceramic tile for decades. Because most old homes only use 1 2 plywood or osb.

If the wood backsplash is firmly attached 3 4 is plenty thick to screw backerboard into or you could remove the existing backsplash and screw the backer through the drywall and into the studs. Tile installed over wood floor systems must have a minimum of 1 1 4 inches of solid material beneath it. Due to the brittle nature of the tile it is important to make certain that the floor system is as stiff as practically possible.

I wouldn t apply your tile to a solid wood backsplash since wood shrinks and expands as humidity and temperature levels change which would tend to pop the tile loose over time. If water seeps through the tile installation to the underlayment it will not cause the wood to swell as happens with interior grade plywood.

Exterior plywood is an acceptable underlayment for tile and is preferred to interior grade plywoods because the bonding adhesives used are waterproof.

Backer board this is the industry standard most preferred by construction pros when installing ceramic or porcelain. Prepare a wood subfloor for tile a successful tile installation project requires a level surface. If the subfloor is 5 8 or 3 4 you can probably apply tile directly to it with no problem. This means you can have a 3 4 inch wood subfloor covered by 1 2 inch plywood cement board or approved gypsum fiber underlayment.

Check for dips in the floor by sliding a 4 foot to 6 foot straight edge in different directions all around the room.
