HardieBacker Cement Board keeps your tiles just where you want them. HardieBacker™ cement board is an ideal solution for wet area floors, walls, and countertops.
Step 1: Preparing the bed for the HardieBacker Cement Board
HardieBacker 250 Cement Board is bedded into a tile adhesive compound. The tile adhesive levels out any minor deviations to allow for a well supported evenly tile backer substrate. Spread the tile adhesive across the floor with a 6mm notched trowel. Make sure that only enough tile adhesive is spread out for a sheet at a time. Applying too much adhesive may result in the adhesive drying out too fast.
Step 2: Installing the first sheet
Sheets must be laid with a 3mm gap from all walls, vanities, baths etc. Sheets are then pressed into the bed of tile adhesive. Install with EZ-grid face up. Note: the adhesive is used as a gap filler only and is no required to attach HardieBacker boards to the sub-base- this is carried out by the application of the mechanical fixings.
Step 3: Fixing Sheets
Sheets are nailed through the body of the board (there are marker guides on the EZ-grid to help) and around the perimeter at 200mm centres. Fixings are 15mm from edges and 50mm from corners of sheets. Fixings can be either 30mm galvanised roof nails or HardieBacker screws.
Step 4: Subsequent Sheets
Subsequent sheets are fixed in the same method. Remember to lay the sheets broken bond or brick pattern.
Step 5: Preparing To Join Sheets:
Wipe down boards with a damp sponge to remove site dust.
Step 6: Sheet Jointing and Taping:
The joints are then jointed and reinforced to provide a more consistent substrate. Apply tile adhesive to joints of HardieBacker Cement Board with a spatula then embed 50mm alkaline resistant tape into tile adhesive.
Step 7: Finishing Joint:
Apply a final layer of tile adhesive feathering joint out to a width of approximately 150mm. Ensure there is no obvious ridge of adhesive as this may affect the final tile finish.
Step 8: Ready For Tiling:
Install tiles as per good building practice, local building codes and national standards.
