HardieBacker tile backer board

Protect your work with the easy to install fibre cement tile backer board famous for its strength and water resistance.

Moisture sensitive areas like kitchens and bathrooms are particularly prone to the negative influence of water on tile backer boards. Get the best protection against moisture damage when you use HardieBacker® tiling backer board. It’s the floor tiling backerboard of choice wherever superior performance is required.

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. HardieBacker® tiling backer board protects your bathroom against moisture damage.

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

Made Better

  • 90% Portland cement and sand
  • No loose aggregate or filler
  • Highest flexural strength and up to three times the compressive strength of competitive cement boards

Installs Better
  • Easy to cut to any size: just score and snap
  • Clean cuts allow edges to align tightly
  • Less dust and debris when cut

Performs Better
  • Unique formulation provides outstanding moisture resistance
  • Excellent heavy tile adhesion
We really didn’t want to have to go back in a few years’ time to make repairs which would damage our bottom line and reputation. In that respect HardieBacker® is really good value as it’s the only backing product which could give us the reassurance we were looking for.

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 6 mm HardieBacker® board. 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.

The HardieBacker® 6 mm board is the durable water-resistant alternative to plywood for tiling on floors. Just like 12 mm HardieBacker® board, it has excellent adhesive properties, ensuring that whatever ceramic or stone tile you use, it will hold strong with applied weights of up to 200 kg/m².

HardieBacker® 12 mm cement board for walls

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

HardieBacker® board 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 board 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.
