Cement board is a cement backerboard designed for use with floors and countertops.
Leave a 1 4 gap between the backer board and walls and 1 16 gap between the sheets of backer board.
For ceramic tile floors the cement board usually rests on a plywood subfloor minimum 5 8 inch thick exterior grade plywood or osb if new ceramic tile is being laid on an existing floor the cement board can usually be laid right over the existing floor finish provided it is in good shape and the extra floor thickness is not a problem.
Layout the cement backer board at right angles to the plywood subfloor so the joints in the backer board are staggered and don t fall on joints in the plywood.
With the plywood in place install the backer board as you normally would.
If you re installing backer board over an existing subfloor 1 4 inch is sufficient.
