Tile Backer Board Fixing Washers are ideal for fixing cement-coated extruded polystyrene tile backer boards, such as our Tile Backer Board Panels. wedi Tile Backer Board, Schluter KERDI BOARD and JACKOBOARD Plano Tile Backer Board. They also perform well with Celotex Insulation Panels, indeed any softer insulation panel that allows the washer to countersink flush into the surface, leaving a smooth finish.
Each washer measures 35mm in diameter and the hole in the centre is countersunk, allowing it to be fixed flush with the surface of the board/panel when fixing it in place.
Available in galvanized steel or stainless steel, Tile Backer Board Fixing Washers come in boxes of 100. The stainless steel washers are guaranteed not to rust and are even stronger than the standard galvanized steel washers.
Each washer has a 5mm hole punched in the centre to allow for a screw. We recommend using 12 washers to fix each 1200 x 600mm board and 24 per 2400 x 600mm board. When you are fixing multiple boards adjacent to each other, you can use one set of washers on the join line between two boards, when fixing the boards to timber stud walling or timber floors.
