Tile Over Cement Board

Thick cement board spans studs spaced 16 in.

Tile over cement board.

Ceramic and porcelain tile are so frequently installed at or above grade level on a cement board underlayment or directly on plywood that it almost seems novel to install tile directly on concrete. And 4 x 4 ft are available but you may have to contact a tile supplier to find them. It depends on how high you want to raise your floor. Installing tile directly on concrete.

Tub to a height of 6 ft requires four 3 x 5 ft. There is no need to install backer board on a concrete substrate ceramic tile can be applied right over concrete provided the surface is flat smooth and free of significant cracks. Laying a cement board under a tile when using a cement backer board you can go with whether a inch thickness or a inch thickness. Yet this application does make sense since concrete is heavy solid and is typically thought of as an unbending uncompromising material.

In order to install tile over cement board you will need to first measure the room. For highly wet areas such as showers and bathtub surrounds cement board typically is attached directly over the wall studs and the studs may be covered with an intervening moisture membrane. Step 1 measure the area. But doing so is a very laborious time consuming process that is likely more trouble than it is worth.

Technically cement board can be laid over a concrete slab as the base for a tile installation. Multiply the dimensions together to give you the exact square footage of the room. Here are the basics of how to install tile over cement board. Use the tape measure and get the dimensions of the space.

A better solution is to prepare and resurface the concrete slab so that it can accept thin set adhesive or a mortar base onto which to lay tile. Add 10 percent to this figure to allow for waste and cutting.
