Attaching ceramic tile to plywood.
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.
Fill in all large gaps and holes as these will prevent proper adhesion of the tiles.
Remove any obstacles from the installation area.
Never install new tiles over existing tiles or onto an unprotected wood or plywood floor.
If possible you should always use concrete board underlayments rather than plywood.
Tiling onto plywood using a standard tile adhesive can be problematic initially i would make sure that the plywood surrounding the pipe work is secure and that you don t have any movement in it.
While tile can be laid on plywood do not install tile directly onto the plywood subfloor itself.
Then i would remove any loose tiles and scrap away any adhesive that is left on the ply and tile you want the ply and tile to be perfectly clean for the next stage.
Use the right type of plywood.
However the floor must be properly reinforced to minimize flexing.
The preferred method for tile installations is to use a sheet of underlayment.
For wall installations plywood is overkill beneath the concrete or fiber board which is designed in five eighths inch material for wall settings.
Then in either case the subfloor should probably be about an.
This will cause either the tile itself to crack and even come loose or cause the grout to crack inside the joints.
This guide will teach you how to properly lay cement backerboard and use mortar to secure and level your subfloor before installing tile.
Unscrew register covers and save the screws.
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.
Unlike wood or drywall sub surfaces cement backerboard will not rot warp or grow mold and mildew when exposed to water.
Unscrew switch plate and outlet covers and set aside.
Plywood or osb flakeboard can expand and contract at too high a rate to be a stable foundation for tile.
Tips for laying tile on plywood subfloor.
There may be times when you want to bond tile directly to plywood or another wood surface rather than screwing down backerboard first.
The silicone or urethane adhesives should work too but the thin set mortars are easier to work with and easier to get full adhesive contact between the tile and its substrate.
How to glue tile to wood.
You can bond tile directly to wood with a flexible adhesive.
Use thinset with a higher latex content.
Backerboard can double the thickness of an installation which can be troublesome in some locations.
For flooring use intervening sheets of plywood.
