Can I 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.
Do I need underlayment for tile on plywood?
On a plywood subfloor, you need either a layer of cement backer board or an underlayment membrane, like Custom Building Products’ Wonderboard and RedGard, between the subfloor and tile for the thin-set adhesive to achieve a good bond.
Can you put Thinset directly on plywood?
Thinset sticks just fine to plywood, but that’s not really the question in your post. First question is to back up and ask what you’re doing exactly. If you’re attaching backerboard to plywood, thinset does not behave as an adhesive.
How thick should plywood subfloor be for 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.
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.
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.
Do you need a moisture barrier under tile?
During patching, most people usually wonder if they would need a moisture barrier under tiles. Well, yes. A moisture barrier should be installed to protect the flooring against moisture or moisture vapor. Trust me; you do not want moisture problems after installing your tiles as they can ruin the entire project.
Can you lay tile on OSB subfloor?
Ceramic tiling can be installed onto 23/32” OSB subflooring panels where the panels are supported by 16” o.c. joist spacing. Manufacturers generally recommend that the deflection of the subfloor system be limited to no more than span/360 under total load.
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.
Do you have to put cement board under tile?
Whenever you’re laying tile on a wood subfloor, you need to first install cement backerboard to prevent leaks and water damage that could harm your flooring and the structure of your home. Unlike wood or drywall sub-surfaces, cement backerboard will not rot, warp or grow mold and mildew when exposed to water.
How do you waterproof a bathroom subfloor plywood?
Apply a bead of the silicone caulk around the entire perimeter of the subfloor. Place the angled part of the nozzle flat against the crevice between the subfloor and the bottom of the wall and squeeze the trigger slowly. Move the caulk gun evenly along the crevice to apply a bead of caulk.
