Step 1
Measure the floor and dry lay the HardieBacker before determining any cuts that need to be made. Make sure none of the board edges end on a subfloor seam, and allow a 1/8-inch gap between all HardieBacker cement boards as well as the walls and cabinets.
Step 2
Mark any cuts that need to be made, using a straightedge to ensure uniform cutting lines.
Step 3
Cut the HardieBacker cement boards by scoring along a straightedge with a carbide-tipped scoring knife and then snapping the board along the line.
Step 1
Apply a layer of thinset where the first HardieBacker cement board will be installed, using a ¼-inch notched trowel (the same size trowel you will use for the tile installation).
Step 2
Lay the first panel of HardieBacker onto the thinset, pressing evenly.
Step 3
Screw the HardieBacker into the floor, using 1¼-inch backerboard screws and using one screw every 8 inches. Offset the interior screws so they are staggered with the outer screws, and make sure no screws are closer than two inches from the edge. (Three-by-five HardieBacker sheets have dots to indicate where the screws should be set).
Step 4
Repeat the process until the entire floor is covered by HardieBacker cement board and ready to tile.

If you want a gorgeous ceramic-tile job, you need to be sure the backer board is in the same plane and the walls are perfectly plumb.

Do You Need A Waterproof Membrane Behind Backer Board?
I also recommend a water-resistant barrier between the backer board and the wall framing. You can put overlapping layers of asphalt felt paper or go with a large sheet of plastic commonly used for a vapor barrier. This layer helps protect the wood framing from wood rot in that rare case where water would soak through the cement backer board.
