More About Cladco Fibre Cement Board
Our Cement Boards are a non-combustible Backer Board for applications including ceiling boards, pre-tiling for walls and floors, surrounding a fireplace.
Exterior grade, A1 fire-rated Fibre Cement Boards are strong, stable and provide superior water resistance. Backer Boards give a longer life when compared to ply or plasterboard. The result is an even, smooth surface to work on, especially in damp-prone conditions, on uneven floors or walls.

Fibre Cement Backer Boards are made from a cement and cellulose fibre mix and are available in thicknesses of 6mm, 9mm, 12mm and 18mm Fibre Cement Boards, depending on the application. Boards can be cut using a scoring knife. It is not recommended to cut the Boards with a dry saw due to dust emission.
Boards can be fixed to surfaces using rapid-set, flexible adhesive, countersunk screws, or backer tape (if tiling). Each Fibre Cement Board provides a stable and suitable backer for many different types of DIY and construction jobs.
Are Fibre Cement backer boards water resistant?
backer boards have brilliant water-resistant properties, and so they will last much longer than plaster or ply alternatives. These Boards provide an even surface for tiling on and can cover uneven walls/floors or moisture-prone areas.
Are Fibre Cement backer boards Fireproof?
Fibre Cement backer boards are produced from a hybrid of cement mix and cellulose fibres, making them an A1 fire-resistant, non-combustible material that is ideal for usage around fireplaces.
How are Fibre Cement backer boards cut?
Before cutting Fibre Cement Boards, it is important to remember to use Safety Gloves when handling, moving and cutting the Boards. *Please note: due to the nature of the materials, it is recommended that a suitable dust mask is worn when cutting the Boards. Wipe away any residue with a damp cloth to avoid dust and particles from becoming airborne.
6mm & 9mm Boards: These slimmer Boards can be cut with a straight edge and a scoring blade/knife. 12mm & 18mm Boards: Cut the thicker 12mm & 18mm Fibre Cement Boards with a circle saw with a built-in extractor and a suitable filter on a sturdy bench. This will provide a straight, clean line and reduces dust entering the surrounding air. *Please note that due to the nature of the materials, it is recommended that a suitable dust mask is worn when cutting the Boards. Wipe away any dusty residue with a damp cloth to avoid particles from becoming airborne.
What can Fibre Cement Boards be used for?
As a multi-use product, Fibre Cement backer boards can be fitted under tiling, onto walls, as replacement floorboards, fitted directly onto cement floors, as ceiling boards, or as a fire surround for fireplaces.
Where can I Install Fibre Cement Boards?
As a multi-use product, Fibre Cement backer boards can be fitted in various ways, thickness depending. Boards of all thicknesses and sizes need to be fitted with a staggered/brick pattern during installation if being used for flooring, to ensure corners do not all meet at any single point.
6mm backer boards are regularly installed for concrete flooring projects because the thinner nature of the Board won’t lift floor levels, whilst producing a creak-free finish. 6mm Boards can be fixed to flooring with a thin-set, polymer-enriched mortar or flexible adhesive applied directly onto the below concrete, then place Boards on top. Allow a set time for a minimum 24hrs, before fastening into place with screws. To seal joints between Boards, add a layer of thin-set mortar over mesh tape with a putty knife
9mm and 12mm Boards are generally designed for use on walls, with the Board’s thickness varying according to the project needs. -For walls in a busy area such as a corridor, or for stud walls, 12mm Boards are suggested because of their high-strength and extra soundproofing qualities. Fix 12mm Boards to stud walls using washers and screws with a minimum 20mm gap from the Board’s edges. -We recommend 9mm backer boards are used for solid walls which can be secured using a quick set, flexible tile adhesive. Once fully set, washers and screws can mechanically fit the Fibre Cement Boards to walls.
18mm Boards are recommended for installation on floors with underfloor heating systems and new build floors, due to improved strength, heat and sound insulation from the thicker Board. Fibre Cement backer boards can be directly fitted onto joists to replace floorboards. Compared to plywood floorboards or other wood-based building materials, 18mm backer boards have minimal risk of movement and are generally more robust.
