How Do You Calculate Thin Set Mortar?
Thin set mortar allows the tile installer to cement tile on a layer of adhesive less than 1/4 inch thick. A thin layer of mortar works best on horizontal surfaces that have already been patched and leveled since it’s less forgiving of flaws than some thicker adhesives. Always check a manufacturer’s recommended coverage guidelines since each can vary, but for calculating an estimate of how much to buy, plan on each 50-lb. bag of mortar mix covering up to 75 sq. ft. of surface area. Measure the room or item to be mortared and record the dimensions in feet or inches. Calculate the surface area of the room or surface by multiplying its length times its width (A=L x W). In a room that is not a precise rectangle or square, you will need multiple area calculations, one for each rectangle or square that makes up the room. Calculate the area of a circular space by drawing a line in the center point of the area and measuring out to the edge of the circle. Multiply that measurement by 2 and then
