Is tile backer board necessary?

Concrete backer board (Durock and WonderBoard), which is the standard material for tile underlayment. Concrete backer board has a solid concrete core, and both sides are faced with fiberglass. It’s waterproof, which makes it ideal for wet-area installations.
What is the purpose of tile backer board?
Backer board is a substrate material for tile. Unlike plywood and other wood substrates that can warp, backer board is hard and flat, so it won’t buckle. Its stability allows you to adhere tile using a thinset mortar, making it relatively easy to create a tile surface that’s level and consistent.
Can I tile 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 tile on OSB board?
OSB will change dimensionally as the moisture in the environment and board changes. Once the RedGard® is dry, tile can be safely installed to the RedGard®-coated OSB with one of CuSTOM®’s polymer-modified thin-set or medium bed mortars.
Can you put tile on drywall in a shower?
You can tile over drywall in areas that are not exposed to excessive moisture, and it is safe. It is not safe to tile over drywall in areas that are exposed to wetness like in the shower. Water in these areas can eventually seep behind the tile and cause damage, mold, or pest infestations.

What goes behind a shower wall?
The insulation behind the tub or shower should be equivalent to the insulation in the rest of the exterior walls and should be covered with an air barrier of cement backer board, rigid foam insulation, or non-paper-faced drywall that is sealed at the edges and seams to provide a continuous air seal.
Do you need to tape drywall behind tile?
Drywall is a good underlayment for ceramic tile, if it is solid and firmly adhered, but special moisture-resistant types should be used in bathrooms, kitchens or other areas exposed to moisture. Drywall also generally needs to be sealed before any tile mastic is applied.
How do you prepare drywall for tile?
How do I prep drywall for a fresh tile installation? Fresh drywall needs up to a month before it’s ready for tiling, but when the time comes, you won’t have to tape the joints.

What type of drywall is used for bathroom walls?
Green. Green drywall is a type of drywall that’s mold resistant and is used in applications where moisture can be an issue—so most commonly, bathrooms. To maximize the mold resistance, use mold-resistant drywall mud, aka joint compound. Green drywall generally costs about 20% more than regular drywall.
Do you need to waterproof cement board in shower?
Contrary to popular thought, tile and grout are not waterproof, and some moisture will penetrate even if sealant is used. However, if you choose to use concrete backerboard, which is much stronger and more durable than gypsum board, a water vapor membrane must be placed underneath it or a sealant applied on top of it.
