Ceramic tile makes a durable flooring material that resists moisture and heavy traffic if it’s installed properly. Before installing ceramic tile on a plywood subfloor, it’s important to put down a layer of cement backer board first. Use corrosion resistant nails or screws to attach the cement backer board to the plywood subfloor.

Cement backer board is more dimensionally stable than plywood and forms a better bond with the thin-set adhesive used to glue the tile down. This means that tile applied to cement backer board resists cracking and popping loose better than tile applied to a plywood subfloor alone.

    • Hi, Cindy! It’s hard to visualize this setup. Can you please describe, in detail, what you’re trying to do, where the wood cabinets are located in relation to the room and the flooring, and any other details that might be helpful?
