Often asked: How To Tile Over Plywood Subfloor?

Can you lay tile directly on plywood?

Tile can be laid on plywood. But do not install tile directly on the plywood subfloor itself. Use an intervening layer of a sheet of thinner plywood.

Can you lay tile on wood subfloor?

While you can lay tile directly over a concrete slab using thin-set adhesive, don’t make the mistake of applying tile directly to a plywood subfloor. No matter how firm the subfloor; the plywood will expand and contract at a different rate as the tile, causing cracks to develop in the grout lines or tiles over time.

Do you need to treat plywood before tiling?

The plywood surface will then be the surface to be tiled. So your nice new clean ply floor isn’t so clean anymore and if it’s not prepared properly prior to tiling, the adhesive will just go onto the dirt on the floor and might not stick! This is why it is better to prime it than not to.

Can you attach tile to wood?

Glue, called mastic, is the least expensive method for installing tiles. Mastic adheres the tile directly to a wooden sub-floor, to a wooden back-splash or onto a piece of plywood. Level the surface using a wood filler. Fill in all large gaps and holes as these will prevent proper adhesion of the tiles.

Can you use 1/4 inch cement board on floors?

Floors: A 1/4-inch minimum thickness is needed, but thicker panels are also fine. Walls: Use 1/2-inch or 5/8-inch-thick cement board, not 1/4-inch. The extra thickness is needed when spanning the studs and it provides a solid base for the tile.

What kind of subfloor is needed for ceramic tile?

The subfloor under the tile should be at least 1 1/8″ thick, with a minimum of 5/8″ thick exterior grade plywood topped by 1/2″ cement backer board.

Can I use cement board instead of plywood?

Cement backerboard is more stable than plywood in high humidity and other wet environments. It won’t swell and buckle the way that plywood does, so it’s safe to use in mudrooms and bathrooms where things like spills and puddles are normal, as well as in areas with high levels of moisture in the air.

Should you lay plywood over plank subfloor?

Take time to make sure your existing planks are well secured in place. Repair any broken planks. Install a layer of at least ½” or preferably 5/8” ply over the existing planks. Like all wooden flooring products, it’s a good idea to acclimatise your plywood before laying it.

What do you put under tile to make it stick?

Underlayment is something you put on top of your substrate to prepare it for tiling. The substrate (or subfloor) is the ground, whether it’s made of plywood or cement. Cement board or backer board are the most standard underlayments.

Does Thinset stick to wood?

Using Thinset To Stick Tiles To Wood Wall Thinset isn’ t the perfect choice for sticking tiles on wood. Firstly, thinset is designed to work with concrete or stone tiles. You can use glue or mastic to attach tiles and wood. They can even adhere tiles on wooden surfaces like wooden sub-floor or backsplash.

What do I prime plywood with before tiling?

If tiling on fibre-reinforced cement sheets, or plywood/chipboard, then we would always recommend priming the reverse side and edges with BAL Bond SBR. This helps protect the plywood from moisture penetration which could cause the board to swell.

What do you seal plywood with before tiling?

Plywood requires the application of a latex based bonding solution to the plywood to seal it and then the use of a flexible cement based adhesive, not pre-mixed tub adhesive.

Should you PVA plywood before tiling?

Short answer. No, never use PVA to prime a surface before applying tiles. The acetic acid produced when cement and PVA come into contact would render the adhesive and grout useless.
