HardieBacker Cement Board is a durable, mould and water-resistant fibre cement tile backer board, ideal for tiling floors, bathrooms, wet rooms, and masonry walls. It serves as a superior alternative to plasterboard, offering excellent protection against moisture and mould growth. With MouldBlock Technology, it doesn't swell, rot, or warp, ensuring the longevity of your tiling. This 12mm thick board boasts high flexibility and up to three times the compressive strength of competitive boards. It fastens directly to any floor, wall, or wooden frame and can be easily cut to size by scoring and snapping, resulting in clean cuts and tight edge alignment. Its fire-resistant properties make it suitable for installation behind boilers or multi-fuel/wood-burning stoves. Composed of 90% Portland cement and sand, it offers excellent heavy tile adhesion and minimal dust when cut. It is suitable for walls and floors when installing ceramic or stone tiles.
