Do you have to tape cement board before tiling?

For tile backer boards such as Durock, Wonderboard, Hardiebacker, Permabase, and others the seams between the board need to be treated with 2-inch alkali-resistant mesh tape. Then a coat of thinset gets flat troweled over the seam. It helps to make the walls that are to be tile more monolithic.

How thick should cement board be for shower walls?

The minimum recommended thickness for the shower wall is 1/2″ because like some of the other boards, they become far too flexible at thicknesses below 1/2″. Foam shower tile backer boards are generally about 4x the cost of cement board.

Do you put backer board under shower pan?

Do you install backer board before shower pan?

Can you tile directly on cement board?

Cement board forms a durable, stable base for tile, and it has no organic materials (unlike drywall, greenboard, or plywood) so it is not prone to mold, rot, shrinkage, or decomposition due to moisture. Ceramic tile laid over cement board is one of the most durable floor or wall surfaces you can install.
