wedi Fixing Dowels are galvanised steel dowels for fixing wedi Tile Backer Board to solid substrates such as walls made from brick, concrete or other materials.
wedi Fixing Dowels can be used with all wedi Tile Backer Board sizes, from 4mm to 100mm. They are available in 4 different lengths: 50mm, 80mm, 100mm and 140mm.
These dowels are applied by drilling an 8mm hole through the wedi board and into the substrate behind. Vacuum out the drilling dust and then drive the dowel through the board into the substrate with a hammer, until the top of the dowel is flush with the board surface. You should allow a minimum dowel substrate bonding depth of 35mm, e.g for a 100mm board the minimum dowel size is 140mm.
