Application

The mixed mortar is applied to the prepared surface with a trowel and then combed through with a suitably sized notched trowel in straight ribs. The tiles should be fixed within the open time of the applied adhesive and pressed into place with a twisting and sliding action to achieve the required contact. For maximum performance at least 80% of the back of the tile should be covered with adhesive. When tiling floors, wet areas or in external locations achieving a solid bed requires buttering the back of the tile immediately prior to placing it onto the ribbed bed, this stops voids from being created beneath the tiles.
