Steps to Cutting Granite Countertops

Step 1: Prepare Your Tools

Prepare all the materials needed including the saw that you will be using. A circular saw is most popular for cutting stone. Make sure you are wearing the correct protective equipment. Inspect the work environment and ensure that no children or pets will wander in the vicinity while you work.

Step 2: Secure You Workbench

Granite is a heavy and durable material but it can break. The last thing you want is to save on labor costs by doing it yourself but end up spending more because of damage. Make sure to cut on a stable cutting surface. Powertools vibrate a lot when cutting. Secure the granite slab by placing clamps. One clamp for every 1-2 feet of granite slab is advised. Clamping may be optional for some, but if you want maximum safety and results it is highly advised. A wobbly workbench can cause uneven cuts or chips on the granite.

Painter’s tape will prevent any chipping on the area of the granite you will cut. It also prevents loose particles from scratching the surface. You will be cutting through the tape.

Step 4: Draw a Cutline

Draw a cut line on the painter’s tape. Even professionals who have done this hundreds of times still use this technique. Do not try to cut the granite without a cut line. Do not try to eyeball this task.

Step 5: Make a Back Cut

Vibrations may actually cause the end to break or crack. This will cause damage to your precious granite countertops and it is absolute. The closer you are towards the end of the cut, the thinner the material. The vily avoidable. Making a back cut at the opposite end of your starting point will help you avoid cracks and breaks.

Step 6: Start Cutting

Position the saw properly. Secure hair and clothing before you proceed with cutting. Make sure you have a tight grip on the circular saw but do not force the cut. Let the saw do its job. Apply only light pressure slowly following the cutline.

If at any point during the cutting you feel exhausted, pause, and rest. Do not force yourself. Shaking from exhausted muscles can cause damage to the granite, and worse, personal injury. Do not be in a hurry to finish the task.

Step 7. Inspect Your Work

Great job! We are all proud of you. Peel off the painter’s tape and inspect and admire your handiwork. Once satisfied, wipe off any loose residue or debris.
