Setting Granite and Marble Tile

Granite and marble are usually quarried and then manufactured to uniform sizes and thicknesses. Standard tiles are 12 inches square and 3/8 inch thick, with one side polished smooth. To minimize chipping, the exposed edges of granite and marble tiles are beveled. In fact, the edges are usually so smooth and straight that the grout joint between tiles can be very thin; sometimes the tiles are installed without any grout joints at all. Do a complete dry run before applying adhesive and laying tiles.
