How to install subfloor porcelain floor tile.

Planning and patience along with these tips will help ensure that you install the quality of finished flooring you are looking for. Plywood or osb flakeboard can expand and contract at too high a rate to be a stable foundation for tile. A number of different types of substrate are used for tile including plywood. Osb panels provide an excellent base for many types of finished flooring including ceramic tiles if careful attention to the construction and preparation of the subfloor is paid in order to avoid costly callbacks.

First changes in humidity make solid wood shrink swell and cup more than plywood. Installing ceramic floor tile to a plywood sub floor has unique challenges beyond that of installation on a concrete floor. I m often asked by homeowners if it s possible to lay down new tile over an existing tile floor. This is not my favorite way to install tile but it can be done as long as the existing tile and subfloor are in good condition and the old tile is thoroughly cleaned and scuffed up with sandpaper to allow the new mortar to grip.

But a number of precautions must be taken to ensure a successful installation. This will cause either the tile itself to crack and even come loose or cause the grout to crack inside the joints. Always follow the manufacturer s installation. While most floor tile these days is installed onto a layer of cement board or similar backerboard it is possible to lay tile directly over plywood.
