HardieBacker

Moisture and mould sensitive areas like kitchens and bathrooms are particularly prone to the negative influence of water on tile backer boards. Whereas traditional materials such as plywood and plasterboard are liable to break or disintegrate when wet, have confidence that your job will last with a board that stays strong and firm, no matter how damp or wet it gets. Get the best protection against moisture damage when you use HardieBacker® board. It’s the floor tiling backerboard of choice wherever superior performance is required.

With its unique cement formulation, HardieBacker board has no loose aggregates or fillers, making a strong and uniform tile backerboard.

HardieBacker EZ GRID® 6 mm for floors

Have confidence that your job will last – resisting rot, swelling and warping when exposed to moisture – when you choose HardieBacker 6 mm. It’s the water-resistant cement backerboard that works perfectly with all types of tile or natural stone flooring.

Our light, easy-to-cut, no-mesh board features our exclusive EZ Grid® recessed pattern, making installation even easier. Install it over an existing timber floor or in conjunction with underfloor heating to optimise heat efficiency. The slim-line 6 mm elevation prevents floor build up and minimizes the transition between floors.

HardieBacker 6 mm with MouldBlock™ Technology is the durable water and mould resistant alternative to plywood for tiling on floors. Just like HardieBacker 12 mm, it has excellent adhesive properties, ensuring that whatever ceramic or stone tile you use, it will hold strong with applied weights of up to 100 kg/m².

HardieBacker 12 mm cement board for walls

Use the durable, mould and water-resistant alternative to plasterboard for tiling on walls. Our 12 mm thick cement backerboard with MouldBlock™ Technology for tile and stone doesn’t swell, rot or warp, so that your tiling work stays put. HardieBacker 12 mm is strong: boasting the highest flexibility and up to 3x the compressive strength compared to competitive boards.

HardieBacker fastens directly to any floor, wall or wooden frame and lines up perfectly with any dry wall, making it particularly quick and easy to install.

Use HardieBacker 12 mm on the floor when additional height is needed. Its fire resistant properties also make it the ideal choice of wall panelling behind a boiler, or even behind a multi-fuel or wood-burning stove.

We have peace of mind that the tiles are mounted onto a backerboard specifically designed for wet areas that will not decay even if exposed to water.
