Glue Tile To Plywood

Remove any obstacles from the installation area.

Glue tile to plywood.

Level the surface using a wood filler. It is a cyanoacrylate adhesive which is single component gives instant strong pasting. If you are working in an interior setting in a dry area where the tile will never come into contact with water you can install the tile directly onto the face of the plywood so long as you use the proper type of thinset. It gives perfect bonding to porous substrates like wood ceramic as it is a thick adhesive.

Unscrew register covers and save the screws. You can bond tile directly to wood with a flexible adhesive. Thin adhesives are unable to provide any bonding to porous substrates as they get absorbed by them. You can bond tile directly to a plywood subfloor and expect it to last.

There may be times when you want to bond tile directly to plywood or another wood surface rather than screwing down backerboard first. Fill in all large gaps and holes as these will prevent proper adhesion of the tiles. Plywood will expand and deform if subjected to moisture or humidity. There are thin set dry set mortars design specifically for adhering ceramic tile to plywood that is designated as an ansi a118 11 thin set mortar.

The joists if they re 2x8 newer code and not 2x10 older code must be braced every four feet with cross braces which minimizes independent flexing of each joist and the subfloor above. However the floor must be properly reinforced to minimize flexing. Try using polyfix instant wood glue. Answer we normally don t recommend to bonding to exterior glued plywood egp but it can be done in interior dry applications.
