Granite countertops should permanently be installed by a professional granite installer, although you may make the necessary cuts yourself. Granite cutting is possible provided you have the right equipment and the required amount of patience.

How to Cut Granite Slab

Equipment You Need

Granite cutting necessitates the use of specialized equipment. To finish the project, you’ll need the following granite cutting tools:

  • Markergranite slab
  • C-Clamps
  • Stable Work Surface
  • Angle Grinder
  • Circular Saw (Wet or dry, with diamond blade equipped)
  • Safety Goggles
  • Ruler or Tape Measure
  • Painter’s Tape
  • Dust Mask
  • Ear Plugs

Using a Diamond Blade to Cut Granite Slab

Step 1: Putting on the Right Safety Gear

To begin, make sure you’re wearing appropriate safety gear (Goggles, dust masks, earplugs).

Step 2: Create an Area for Your Work

The next step is to organize your workspace. Place the granite slab on the workbench or other solid cutting surface. To keep the granite block in place, use C-clamps spaced about every two feet.

Step 3: Determine the Size of the Area to be Removed

Determine where you want to cut using the ruler or tape measure.  This measurements needs to be precised since once you have made the cut, you can not undo it.

Step 4: Apply the Painter’s Tape

Mark the area where you will be cutting  using a painter’s tape. After that, using the ruler or tape measure as a reference, draw a straight line on the tape (A ruler is better for ensuring a straight line).  This is a very crucial part.  The measurement needs to be accurate it will act as a visual guide for cutting.

Step 5: Prepare the Saw

Make sure the saw you’ll be using is ready to go before you start working. There must be a diamond blade on the saw, regardless of whether it is a wet or dry saw.

Step 6: Get the Granite Saw Out and Start Cutting

Cut the granite once you’ve finished the previous stages. Don’t be hasty with the saw; proceed slowly. If you push the saw too hard, you run the danger of ruining the cut and the whole project. For your protection, always keep a safe distance from the action and use two hands.

Step 7: Wet the Granite with a Garden Hose

As you make the incision, have a helper spritz water on the granite. Granite cutting generates a lot of heat and pressure, so you have to take precautions to avoid damage. You don’t want for the saw to overheat while you’re using it. Use water to keep the saw wet while cutting.

Step 8: Observe the Saw at All Times

When you’re cutting, keep your eyes on the saw at all times. You run the danger of messing up the cut and injuring yourself if you do this.

Step 9: Double-check Your Shaved Hair

Always check your cut if it is adequate after completion. If you’re happy with the results, you may either finish the project or go to the next cut by marking and cutting again. Reapplying tape and re-cutting might be used to fix slight mistakes if you’re not happy.
