Simplify the cutting of ceramic tiles by using a wooden base board slightly larger than the size of the tiles to be cut. Secure a taut length of galvanized wire across the board with nails or screws. Score through the glazed surface of the tile and place it – glazed surface uppermost – on the board with the scored line over the wire. Press firmly on each side of the scored line to snap the tile cleanly. When cutting off a narrow strip of tile, place a piece of wood on the narrow strip and press down on it. This ensures that pressure is evenly applied along the complete length of the cut. For a very narrow strip, use pincers to nibble off the waste material and smooth down the cut edge with glasspaper or a file if necessary.
