To install granite countertops correctly, you will need to know in advance what you'll be up against. You'll either need to know how to cut and build your countertop opening, or have an experience craftsman build it for you. You'll need to cut the stone itself. If you want it done right and don't have the experience you need, hire someone to do it for you. Finally, you'll need to seal it properly to keep it from absorbing stains. To tackle all three of these challenges, you'll need the right tools, the right materials, and the right instructions.

Step 1 – Preparing Base and Fixtures

Installing a new countertop can be time consuming, so be prepared to spend the needed time. Begin by removing the old countertop, all old fixtures, the old sink, and any appliances, such as your dishwasher and garbage disposal. Remove your old backsplash. Clear out the kitchen to give yourself the space you'll need to work, as you will save yourself a lot of frustration if you do this before hand. Before removing the sink, dishwasher, and disposal, be sure you shut off your water and disconnect all electrical connections.

Step 2 - Cut and Finish the New Countertop

When cutting your granite countertop, you'll definitely need a wet saw with a diamond blade and a grinder. If you don't own a wet saw and grinder, rent them or have someone who has a wet saw and experience cut the countertop for you. If you cut it yourself, be prepared to deal with the mess that will be created from the water coming off your saw. Be prepared to not only cut the granite, but to also smooth its edges with a grinder. Be sure to do this before you try to fit the counter onto its base. You'll need to know the right size saw blade to use. Size will be determined by the thickness of your granite slab. If you don't now how to match up these two factors, ask someone who knows.

Step 3 – Installing Your Granite Countertop

Be prepared to have help carrying and placing the granite countertop. Be sure the base is strong enough to support it, as it could weigh up to 600 pounds. This might require you to have as many as six strong helpers. Before placing the countertop on its base, apply epoxy to the cabinet's top surfaces where it will be glued to the countertop. Then, lift the countertop into place. Be sure it is positioned correctly.

Step 4 – Installing the Sink and Backsplash

Install the sink under the countertop. Apply epoxy adhesive where the countertop connects to the sink. While your epoxy is drying, keep both the sink and countertop fixed together by using clamps and a flatbar. Attach and glue the backsplash and apply caulk where needed. Finally, reinstall and connect your appliances and turn on power and water.
