How to Sand Quartz Edges: Materials Needed

Step 1: Prepare Your Workspace

Choose a well-ventilated area to work in. Put on your safety goggles and rubber gloves to protect yourself from quartz dust and any potential sharp edges.

Step 2: Inspect the Quartz

Before you start, examine the quartz edges that you wish to sand. Identify any particularly rough spots or irregularities that will need extra attention.

Step 3: Attach Coarse-Grit Sanding Pad

Attach a coarse-grit diamond sanding pad to your angle grinder or hand-held stone polisher. Make sure it’s securely fastened.

Step 4: Wet the Quartz

Lightly wet the quartz edges with water. This helps to minimize dust and improves the sanding process.

Step 5: Start Sanding

Turn on the angle grinder to a low-to-medium speed. Apply even pressure and begin to sand the quartz edges in a sweeping motion.

Step 6: Move to Medium-Grit

Once you’ve smoothed out the rough spots with coarse-grit, switch to a medium-grit pad. Repeat the sanding process until the surface becomes more refined.

Step 7: Final Sanding with Fine-Grit

Replace the medium-grit pad with a fine-grit pad. Do a final pass over the quartz edges to achieve a smooth finish.

Step 8: Inspect and Finish

Once you’ve completed the sanding process, inspect the quartz edges to ensure you’ve achieved the desired smoothness. If satisfied, your project is complete.
