Ceramic Tile Over Wood Subfloor Installation

Tile floors are heavy and tile is a hard material.

Ceramic tile over wood subfloor installation.

Try laying tile over 1 2 durock or hardie and see what happens when the joists are 19 2 or 24 on center. While tile can be laid on plywood do not install tile directly onto the plywood subfloor itself. First changes in humidity make solid wood shrink swell and cup more than plywood. Hope you didn t like your beautiful new tile floor.

A plywood subfloor must be structurally sound and able to support the installation. Lay down inch exterior plywood the opposite direction and screw to the inch. The 2 3 s would be standing up on their side so. Second the strength of wood boards isn t always consistent.

If installing over an appropriate wood surface sand the wood to make it smoother and remember that the installation will work better over a subfloor at least 1 1 8 inches thick. Lay down inch exterior plywood and screw into the 2 3 s every 8 inches. If you must install over such surfaces it is best to install a backer board over the old surface and install the tile on the backer board. According to backer board manufacturers and tile setters installing backer board directly over an old solid wood subfloor is risky for a couple of reasons.

Cement backer board can provide a solid flat surface to install tiles on if you have a wood subfloor. Use intervening layers of two sheets of plywood.
