  • A tile backer board is a rigid, water-resistant building board that provides a stable substrate for wall and floor tile installations. It helps improve durability and is commonly used in bathrooms, wet rooms and shower areas.

  • Tile backer boards are recommended where additional stability, moisture resistance or waterproofing is required. They create a reliable surface for tiling over timber, masonry and other prepared substrates.

  • Tile backer boards are suitable for bathrooms, kitchens, wet rooms, shower enclosures, walls and floors. Some boards are also compatible with underfloor heating systems.
