How to put hardibacker on floor.

Never install new tiles over existing tiles or onto an unprotected wood or plywood floor. If you re preparing to do a ceramic floor or wall installation it s recommended that you install hardiebacker cement board on your subfloor or wall before you begin to lay the tile. If your floor meets the requirements the next step is to ensure that it is structurally sound and free of damage. To achieve the ideal flat surface most contractors rely on the backer board cement backer board is a thin layer of concrete designed to be setting surface upon which tile can be installed.

If installing hardiebacker cement board over existing floor ensure the floor is flat. Hardiebacker cement board may be installed under or over vinyl composition tile vct and other resilient flooring. Unlike wood or drywall sub surfaces cement backerboard will not rot warp or grow mold and mildew when exposed to water. Hardiebacker moisture and mould sensitive areas like kitchens and bathrooms are particularly prone to the negative influence of water on tile backer boards.

The backer board comes in different sizes and you will pick the right one depending on the type of floor you are installing. It s not really there to stick it down although it doesn t hurt. Floor tiles should be installed over smooth flat surfaces. To avoid building up the floor too high you can use 1 4 in thick backer board instead of 1 2 in.

Whenever you re laying tile on a wood subfloor you need to first install cement backerboard to prevent leaks and water damage. The plywood adds stiffness and stability to the floor. With the plywood in place install the backer board as you normally would. For best results remove existing floor covering especially if it is in poor condition.

You ll still need to screw it down with deck screws 1 or 1 1 4 and avoid the joists or nail it down with roofing nails. Replace any warped missing or uneven sections of flooring so that you have a flat and clean surface. Keep fasteners between 3 8 and 3 4 from sheet edges and 2 in from sheet corners.
