Product Overview
HardieBacker 6mm Tile Backer Board with a 1200mm length, 800mm width, and 6mm thickness. A cement-based building board specifically developed for use beneath tile finishes in wet or high-moisture areas such as kitchens and bathrooms.
Manufactured with innovative MouldBlock Technology, it provides a durable, water- and mould-resistant alternative to plywood and plasterboard. The board’s dense cement composition delivers high compressive and flexural strength, ensuring tiles remain secure under applied loads up to 200kg/m².
Its paper-free surface prevents rot, swelling, or warping, even when exposed to prolonged dampness. Designed for floor applications and suitable as a substrate for vinyl, natural stone, and ceramic tile installations.
Features & Benefits
- MouldBlock Technology: Prevents water absorption and mould growth, maintaining long-term board integrity.
- High compressive strength: Up to three times stronger than competitive boards, providing a solid foundation for heavy tiles.
- Superior adhesion surface: Ensures secure bond strength with tile adhesives for finishes up to 200 kg/m².
- EZ Grid recessed fastener pattern: Simplifies screw alignment and speeds up installation.
- Clean cutting properties: Easily scored and snapped with a knife for accurate, dust-minimised cuts.
- Non-paper, non-mesh composition: Eliminates risk of delamination or edge breakdown in humid environments.
- Thermal suitability: Compatible with underfloor heating systems and provides stable insulation performance.
- Dimensional specification 1200mm x 800mm x 6mm: Provides full coverage with minimal joints and consistent board rigidity.
Applications
- Bathroom and wet room floors: Provides a moisture-resistant substrate for ceramic or stone tiles.
- Kitchen flooring: Prevents tile cracking over timber subfloors by reducing deflection.
- Countertops and work surfaces: Offers a stable, water-impervious surface for tiled finishes.
- Masonry walls: Serves as a durable lining board where high humidity or direct water contact occurs.
Installation Guidance
- Floor preparation: Ensure substrate is level, clean, and free from debris before fitting.
- Fixing to timber floors: Use insulation fixing washers and corrosion-resistant screws to secure the board.
- Fixing to concrete floors: Apply flexible tile adhesive to a primed surface for full contact bonding.
- Cutting and shaping: Score and snap using a utility knife and straight edge; shape around pipes or fittings as required.
- Joint treatment: Stagger board joints and tape using alkali-resistant mesh before tiling for a continuous surface.
Compliance & Performance
- Material composition: 90% Portland cement and sand with no loose aggregate or filler.
- Load capacity: Designed to carry up to 200 kg/m² of adhered tile weight.
- Water and mould resistance: Fully impervious to rot, swelling, and degradation under wet conditions.
- Thermal compatibility: Safe for use with underfloor heating systems and stable under temperature variation.
- Important note: Always wear gloves and safety eyewear when cutting or handling boards to prevent injury or irritation.
