Once you've completely installed your cement boards, your result should look like wall to wall backer board sheets.

The cement boards make for a strong, level, waterproof surface, making for the perfect tile underlayment for Stone and Ceramic floor tiles,

Tips for a Cement Backerboard Layout

* Laying 1/2 inch of cement board, two layers of tile mortar and 1/2 inch of tile will make a difference in the height of your floor.

* If you're starting out with the same height or even close as those of surrounding floors this could create a tripping hazard, even if you use a wooden reducer threshold.

* The maximum height difference in floors should be 3/4 inch, so limit the height difference as much as possible.

* You can do this by Removing old flooring before laying the backer board sheets.

*You may also choose thin porcelain stone like tiles instead of thick natural stone ones.

* Make sure your subfloor is smooth, clean, and free of debris, and Plan your layout by starting in a corner.

* Use strips of 1/4 inch plywood to create a gap around the perimeter of the floor.

* For tiling your backer board sheet should be laid rough side outward, and plan your layout so that none of the joints of the cement boards, falls directly over the joints of the plywood subfloor.

* You want to stagger the cement board joints so that there is no place where the four corners of the cement boards meet, and also keep a 1/8 gap between the cement boards.
