Granite countertops add a sophisticated touch to any kitchen. Installing granite is not as tedious of a chore as it may seem. Continue reading to learn how to make the project easier.Measure The CabinetsCarefully measure from the back wall to the front of the cabinets, from the side wall to the side of the cabinets and allow an additional inch for an overhang. Be sure to keep the measurements consistent. Make note of counter slabs that meet and must be cut at an angle.Order Prefabricated GraniteThe most important thing to remember about this project is to only use granite that is intended for DIY projects. There are several different companies that sell prefabricated granite for counters. One of the best and most reliable choices is DoItYourselfGranite.com. This company has a wide selection of granite slabs. Choose the sizes that are closest to the cabinet measurements. Granite is fairly brittle, so it's best to use thick slabs. Install PlywoodVisit a lumber yard or home improvement store. After finding some 3/4" plywood, ask someone to cut pieces that match the cabinet measurements. Install the pieces carefully so there is no overhang. Plywood has a tendency to split, so be sure to drill a pilot hole before putting the screws in. Avoid using nails to attach the wood to the cabinets.Cut Granite SlabsDepending on the size of the cabinets, it may be necessary to cut the slabs after they arrive. If this is the case, use a circular saw with a dry-cut diamond blade with segments. Use kraft paper or another stiff material to make a template of the countertops. It's best to do this before cutting the granite, especially for homes that have slightly uneven walls.Install Granite SlabsBe careful not to break the slabs during installation. Use 1 1/4" screws under the plywood to raise or lower the countertop. Have several strong helpers available to assist with lifting the heavy granite slabs. Put dollops of silicone around the plywood's perimeter, and place caulk around the sink rim. Lower the countertop slabs carefully into place. Put several drops of polyester-based resin along the seams to join them. Be sure to read the instructions on the package to fully understand how to use it. After finishing these steps, wait 30 minutes before using a seam stone. Turn the device to a low speed, apply firm pressure and use circular motion. Granite countertops last many years if properly cared for.
