Tile Installation

Installing Tile Over Backerboards

Cement ceramic tile backerboards may also be installed over plywood subfloors and should be secured using 1-1/4″ corrosion resistant roofing nails or 1-1/4″ ribbed wafer head screws in combination with a thinset mortar bed. Screws or nails should be installed every 6″ to 8″ on center. Subfloor deflection should not exceed L/360 of span. Ceramic tile backerboards will add to the height of your new floor and may require height reducing thresholds or transition strips where tile meets carpet, vinyl, etc. Doors may also need to be trimmed. Refer to the backerboard manufacturer for specific product recommendations and limitations.

To prevent moisture from damaging the plywood subfloor we recommend that a waterproofing membrane be applied per the manufacturer’s instructions over all ceramic tile backerboard surfaces installed in wet areas, including shower and tub wall facings.
