Dry-Fit the Granite Tiles
Position one granite tile on the countertop area, with a 1/8-inch overhang, to use as a guide. Snap a chalk line and dry-fit the other tiles, cutting with a wet saw as needed. Glue the tiles directly to the cement board with an adhesive recommended for tiles. Weight the tiles with bricks or other heavy objects while the adhesive dries. Always wear eye protection when working with a wet saw. Maintain the 1/8-inch overhang all the way around the countertop. This will bring the finished stucco sides flush with the edge of the counter. Let cut tiles dry completely before installing. Wet tiles won't adhere properly to the cementboard. For a finished look, choose tiles with a bullnose (rounded) edge for the outside edges. The crew used tiles that were cut to butt up against each other, eliminating the need for grout.
