QUESTIONInstalling Tile on wood stair risers - I am interested in installing some ceramic tiles on staircase risers. I removed old carpeting from the staircase and got down to the wood staircase.
I would like to leave the treads wood and install possibly Talavera tiles over the remaining wood substrate risers.
What might be the recommended procedures and can I install the ceramic tile over the wood without using backerboard as well.
ANSWERANSWER: I assume this is an interior application.
There are products that will allow you to bond ceramic tile to exterior grade plywood, but it is not considered the best substrate to bond to. It would be better to use a cementitious backer board.
Make sure the stairs are sturdy. Thin-set and screw in a cement backer board (CBB) onto the wood risers. Thin-set your tile onto the cement backer board using an appropriate multi-purpose polymer or latex modified thin-set for the tile you are using. Leave a 1/4" gap along the perimeter of the tile to any restraining surface and caulk it with a silicone or urethane sealant that meets ASTM C920. Grout your tile with a polymer or latex modified grout.
