Step-by-Step Guide

Now, let’s dive into the process of trimming your granite countertop:

  1.     Safety First:

Before you begin, ensure you are wearing the necessary safety gear, including safety glasses, a dust mask, ear protection, and gloves.

  1.     Prepare Your Work Area:

Place the countertop on a stable surface, such as sawhorses or a workbench. You may want to use plywood or other sturdy material to support the countertop securely.

  1.     Measure and Mark:

Use your measuring tape, pencil, and straightedge to mark the area you need to trim. Double-check your measurements to avoid any mistakes.

  1.     Set Up the Saw:

Attach the diamond blade to your circular saw, making sure it’s securely fastened. It’s crucial to use a blade specifically designed for cutting granite.

  1.     Make the Cut:

Position the saw along your marked line, ensuring the blade is on the waste side of the countertop. Start the saw and make a slow, continuous cut along the line. It’s important to use a steady hand to prevent chipping.

  1.     Keep the Blade Cool:

To prevent overheating and minimize dust, it’s recommended to have a constant flow of water over the blade while cutting. You can use a water bottle or a garden hose for this purpose.

  1.     Clamp a Straightedge:

To help guide the saw and maintain a straight cut, clamp a straightedge to the countertop, ensuring it aligns with your marked line.

  1.     Smooth the Edges:

After making the cut, you may notice rough edges. Use a diamond sanding pad or a stone polisher to smooth the edges and create a finished look.

  1.     Test the Fit:

Before finalizing the installation, check the fit of your trimmed countertop. Ensure it matches the appliance or sink you’re installing.

  1. Apply Granite Adhesive:

If needed, use granite-specific adhesive to secure the trimmed piece in its new location. Follow the manufacturer’s instructions for the adhesive.

  1. Clean Up:

Finally, clean up the work area and remove any dust or debris. Properly dispose of any waste material and used diamond blades.


Trim granite countertop may seem like a challenging task, but with the right tools, safety precautions, and careful execution, it’s a manageable DIY project.
