Ceramic tile is used in walls, floors and counters. Most tiles you cut will be straight cuts meant to adjust the width or length of your tile. Occasionally you will run into an angle that is less than 90 degrees. These situations call for a mitre cut. Making a mitre cut with your wet saw means taking precise measurements of the area. This is why all mitred cuts should be made after the rest of your tile is already set in adhesive so you will get a precise measurement, a tight cut and a tight fit.
Measure from the edge of the tiles on one side of the empty space to the corner of the angled wall. Transfer that measurement to your new tile and make a mark.
Measure from the opposite wall to the remaining corner of the angled wall. Transfer that number to the tile and make a mark.
Line up a speed square between the marks on your tile. Draw a line between the marks.
Turn on the water supply to a wet saw. Turn on the power switch to engage the blade of the wet saw.
Hold the tile firmly. Cut a small piece at a time off the tile by pushing it gently into the blade. Continue cutting away pieces of the tile until you reach your cut line.
Work gloves, safety glasses and hearing protection are required when using a wet saw.
