Setup, Compatibility & Care
- Preparation: Ensure the subfloor or wall studs are level and structurally sound.
- Cutting: Use a scoring knife to score the board, then snap along the score line for clean cuts. 
- Fastening: Secure the board to the subfloor or studs using appropriate screws or nails designed for cement board. Follow the manufacturer's recommendations for fastener spacing.
- Seaming: Leave a small gap (e.g., 1/8 inch) between boards and fill with thin-set mortar or a specific joint treatment for cement board.
- Tiling: After the board is installed and the seams are treated, you can begin tiling using a thin-set mortar suitable for cement board. Follow tile manufacturer's instructions for mortar and grout.
Compatibility: HardieBacker is compatible with most types of ceramic and stone tiles. Use a mortar recommended by the tile manufacturer.
Care: Clean the board with a damp cloth or sponge. Avoid abrasive cleaners.
