Product Details

Firstly, to realise the full benefits of JamesHardie products it is recommended wherever possible to use the correct accessories. James Hardie produce a range of HardieBacker screws for floors, for walls, for metal frames.  These screws are self-countersinking, they cut a shaped hole in the fibre cement backerboard.  When the screw is then tightened the head finishes flush with the surface of the board.

For wood frames (for floors) use:

HardieBacker screws 5.0 x 25mm, the diameter of the head is 10 mm PZ2. These screws from JamesHardie require no pre-drilling. Similarly they have a self-countersinking head for a perfect flush finish. Each bag of 100 screws includes a PZ2 drive bit

For wood frames (for walls) use:

HardieBacker screws 4.0 x 35 mm, the diameter of the head is 10 mm PZ2. The HardieBacker screws for flooring require no pre-drilling. Similarly they have a self-countersinking head for a perfect flush finish. Each bag of 100 screws includes a PZ2 drive bit.  Wall screws here

Because HardieBacker is supplied in 6mm and 12mm thickness it can be used on floors, walls and work surfaces. The HardieBacker EZ Grid 6mm is primarily used on floors, the HardieBacker 12mm is mainly for walling applications. HardieBacker is made of Portland cement, ground sand, cellulose and selective additives. However it does not contain any undesirable elements such as asbestos, formaldehyde, gypsum or glass fibre. Therefore this means HardieBacker cement board is water resistant, immune to water damage and won’t rot, swell or warp. HardieBacker, an ideal flat surface for tiling on.
