Description
Dukkaboard XL 6mm Fibre Cement Tile Backer Board – 1200 x 600mm
The Dukkaboard XL 6mm Fibre Cement Board is a strong, durable and reliable tile backing board designed to provide a stable foundation for floor tiling installations. Manufactured from high-quality fibre cement, this heavy-duty tile backer board is ideal for strengthening existing floors and preparing surfaces for ceramic, porcelain and natural stone tiles.
With a slim 6mm thickness, Dukkaboard XL is particularly suitable for overboarding concrete, chipboard and stable timber floors, helping to create a solid, dependable tiling substrate without significantly increasing the overall floor height.
Its robust construction helps reduce the risk of movement-related tile cracking, loose tiles and deterioration of underlying floor surfaces, making it an excellent choice for both domestic renovations and professional tiling projects.
Dukkaboard XL is also ideal for installation over stable timber floors where wet underfloor heating systems are already fitted beneath the flooring, providing a strong and dependable base for the final tiled finish.

Why Choose Dukkaboard XL 6mm?
A successful tiling installation starts with a strong, stable substrate. Uneven or insufficiently supported flooring can contribute to cracked grout, loose tiles and premature failure of a tiled surface.
Dukkaboard XL offers a practical solution by providing additional reinforcement to suitable existing floors. Its solid fibre cement construction helps create a dependable base capable of supporting a wide range of tile finishes, including heavy natural stone.
The 6mm thickness makes it particularly useful for renovation projects where floor height needs to be kept to a minimum while achieving a strong foundation for professional tiling.
Installation Guidance
Before installation, ensure that the existing substrate is clean, dry, stable and appropriately prepared. Boards should be installed using compatible adhesives, primers and mechanical fixings where required, following the manufacturer's installation instructions.
Correct board positioning, staggered joints and suitable fixing methods are important for achieving a long-lasting tiled finish.
