Granite is one of the hardest materials and is resistant to heat. You need to seal it because it does absorb stains. If you want to install your own granite countertops, see how much it costs you to have the place that sold you the granite cut out the openings for the sink and cut the slabs to the appropriate length. You’ll find that having a pro cut the stone makes the job of installing the granite countertops easier.
Remove all the old fixtures, the old countertop and the sink to prepare for the installation of the granite countertops. Either glue in or screw on the sink to the frame. Use a putty knife to loosen the glue. Pry away the old backsplash.
Take out any of the appliances that might be in the way. You need plenty of room, and this simple task makes the job a lot easier. Remove the dishwasher if you think it's necessary. You should have the water shut off, but you'll still need to disconnect the electric and the plumbing. Once you remove the old countertop, you should reinstall the dishwasher before you put in the granite countertop.
Spread the appropriate epoxy for granite onto the tops of the cabinet. Secure the help of friends and family to carry the countertop into the house. You'll need the strongest people you know since the countertop may weigh as much as 600 pounds. This is one project in which "beer doesn't make it better." The countertop is extremely heavy and you'll want everyone to have a clear head.
Install the sink that mounted under the granite. Use the appropriate epoxy adhesive to glue the sink to the underside of the granite. Clamp it into place with clamps and a long flatbar to hold it until the epoxy dries.
Install the backsplash by using an adhesive to glue it to the wallboard. Seal the granite with a special spray. You'll have to do this once a year to keep it from absorbing oils.
