Trimming ceramic tiles
Often it is necessary to trim the perimeter tiles. There are many fancy tile cutting devices on sale, some are equipped with measuring and marking devices. The most common floe for cutting ceramic tiles has a sharp tip made of hardened steel, which cuts deep into the glaze, allowing the tile to be broken along the marked line. Another type of cutter has a small glaze drawing wheel and a vise to hold the tile.
Before trimming the perimeter tile, rest it with the edge against the wall, measure out the missing width and mark the cut line with a pencil. Always make an incision on the glazed side. If you are using a regular cutter, place two matches under the tile at the cutting height, then press down firmly on both sides. Using a vise cutter, clamp the plate in it. Smooth the edge with a glaze file.
