Installing granite tile in your home, most likely as a countertop, is a great way to add value to your home while updating its decor. Using granite tiles instead of a custom granite slab countertop will also save you money.

Step 1Screw the 1/2-inch cement backer board to your plywood substrate. Countersink the screws just below the backer board surface.

Step 2Cut 2-inch strips of cement backer board and screw those to the edges of substrate finish so they are flush with the top.

Step 3Set your level on top of the cement backer board at various locations to make sure the entire surface is level, side-to-side and front-to-back.

Step 4Spread a thin-set mortar with a notched trowel to the top of the cement backer board closest to the edge.

Step 5Lay full tiles on the outer edge first, butting them together. Overhang that row of tiles enough to compensate for the edging you'll put on last.

Step 6Use a tile saw to cut the tiles that will fit along the wall and along the edge of your counter. No matter what size of tiles you use, chances are they will not all fit perfectly and some will have to be cut.

Step 7Apply the thin-set mortar to the side of the cement backer board (and an optional backsplash) and position the edge tiles. Make sure they line up with the ones on top for a professional look. Use tape to hold the edge tiles until the mortar has dried.

Step 8Add grout to the seams between the tiles with a rubber-padded grout float. Wipe off any excess grout with a wetted sponge. You can also add an optional sealer to the grout once it has dried to help prevent stains.
