How to use

These 10mm construction boards can be fixed to both walls and floors. Always stagger the joints of the boards and leave a 5mm gap around the perimeter of the room.

Timber Floors
Boards can be fixed using either flexible tile adhesive or the dedicated washers together with conventional screws. If using washers and screws, placed a washer under the screwhead and tighten the screw until the washer bites into the board. You will need to use 15 screws per board.

Concrete Floors
New concrete must be fully cured. Always seal the concrete with primer, before fixing the boards with a full bed of flexible tile adhesive. Use an 8mm notched trowel to apply the adhesive.

Stud Walls
Ensure the timber studs are set to 300mm centres and fix using screws and washers, as above. The board edges must be supported by noggins.

Brick/Block Walls
Boards can be fixed using a full bed of tile adhesive, as above.
