How to tile over plywood subfloor.

Use intervening layers of two sheets of plywood. Once the surface is completely covered cover the adhesive with the fiberglass based paper and smooth out any wrinkles or bubbles with a broad drywall knife. While tile can be laid on plywood do not install tile directly onto the plywood subfloor itself. Use thinset with a higher latex content thinset is the wet base that you first trowel on the plywood to make the tile stick.

Concrete board concrete board also called backer boardcomes in 1 4 and 1 2 thicknesses and is usually sold in 4 x 6 sheets. There are two materials commonly used for laying ceramic on plywood or osb that are applied before the tile. The old fashioned mud method of floating a thick mortar bed in preparation for the tile has given way to using cement backer board over a plywood subfloor. The plywood will expand and contract at a different rate as the tile causing cracks to develop in the grout lines or tiles over time.

Begin by applying the thin skin adhesive to the plywood with a smooth trowel. It should be fastened to the subfloor using thinset and then screwed down every 10 square.
