How Do You Cut Ceramic Tile Diagonally?
Cutting ceramic tiles at a diagonal direction across the face is a little trickier than making a straight 90-degree cut across the surface, but the principle is the same. Unlike stone tile, which requires a wet saw, ceramic can be cut by simply scoring the glazed surface of the tile and then applying downward pressure on either side of the score until it breaks in a straight line. Score-and-snap tile cutters are made for this type of cutting, which goes much quicker than any other method. Use your tape measure and wax pencil to put two side-by-side marks on the tile where you need it cut. Lay your straight-edge across the tile, intersecting the two marks. Draw a straight line through them with your wax pencil. Set the tile on your tile cutter. Position it so the wax-pencil line is lined up with the slide bar that holds the blade over the platform. Set the blade on the back edge of the tile, right on the line you made. Press down firmly on the handle and slide the blade forward, scoring
