How to Bevel Quartz Countertops

Beveling the edges of quartz countertops can add an elegant, high-end look to your kitchen or bathroom. With the right tools and techniques, beveling quartz is a doable DIY project. Here is a step-by-step guide on how to bevel quartz countertop edges.

What You’ll Need

  • Quartz countertop slab
  • Diamond polishing pads – 50 grit, 200 grit, 800 grit, 1500 grit and 3000 grit
  • Variable speed angle grinder
  • Extension cord
  • Water supply – spray bottle or garden hose
  • Eye protection and respirator mask
  • Gloves
  • Rags
  • Mineral spirits
  • Pencil
  • Straight edge
  • Painter’s tape

Step 1: Mark the Bevel Line

The first step is to mark where you want the bevel to be located. Using a pencil and straight edge, draw a line 1/8” to 3/8” from the bottom edge of the countertop. This will be your guide line for the bevel angle. Apply painter’s tape just above the pencil line to protect the surface.

Step 2: Grind the Bevel Edge

With eye protection and a respirator mask on, use the angle grinder with a 50 grit diamond pad to grind down the edge at a 45° angle up to the tape line. Work slowly and smoothly as you grind. Keep the grind line as straight as possible.

Spray water on the surface to keep dust down and rinse grit from the diamond pad. Make light passes back and forth until you achieve the bevel angle. Vacuum up slurry occasionally so you can see your progress.

Step 3: Smooth and Polish

Once you’ve established the bevel angle with the 50 grit pad, switch to the 200 grit pad. Rinse the pad and continue polishing to refine the edge. Apply light pressure as you smooth away grinding marks.

Gradually step up through the 800, 1500, and 3000 grit pads. Rinse and wipe down between each pad. Check for a consistent bevel angle and straight grind line as you polish. Spray with water and keep pads clean.

After the 3000 pad, wipe the countertop down with mineral spirits to remove residue. Rinse thoroughly and allow the surface to dry completely. Remove painter’s tape.

Step 4: Protect the Surface

Once polished, seal the beveled edge using a penetrating sealer made for quartz. Apply sealer with a clean cloth and let it soak in for 5-10 minutes. Buff off any excess. Reapply yearly or as needed to protect the quartz and keep the beveled edge looking sharp.

Tips for Beveling Quartz Countertops

  • Work slowly to avoid chipping. Apply light, even pressure.
  • Keep angle grinder moving constantly to prevent burning the surface.
  • Wear quality eye and ear protection – safety glasses, goggles, face shield.
  • Use grinder handle for better control and minimize vibration.
  • Have a helper spray water to control dust.
  • Check edge frequently with straight edge to ensure consistent bevel angle.
  • Begin polishing with 200 grit after establishing bevel with 50 grit.
  • Keep polishing pads clean and rinsed to increase effectiveness.
  • Thoroughly clean surface before sealing with mineral spirits.

Beveling quartz countertop edges takes time and care, but the end result is worth the effort. Resist the temptation to rush through steps. With the proper grinding and polishing, you can achieve a smooth beveled edge that gives your countertop a high-end custom look.

Frequently Asked Questions About Beveling Quartz Countertops

Can I bevel quartz myself or do I need a professional?

Beveling quartz countertops is a DIY-friendly project if you have the right tools and patience. An angle grinder with diamond polishing pads allows a homeowner to bevel their own quartz. Go slowly and carefully. Hiring a pro ensures an expert bevel but isn’t required.

What bevel angle should I grind my quartz countertop?

A standard bevel angle for quartz countertops is 45 degrees. This creates a noticeable beveled edge without getting too sharp. Smaller 30 degree bevels are possible for a more dramatic look.

How wide should the bevel be on a quartz countertop?

Bevel widths can range from 1/8 inch to 3/8 inch deep. A 1/4 inch bevel is common. The width is based on personal preference and edge thickness. Wider bevels are better on thicker edges.

Can I bevel just the front/visible edges?

Yes, you can bevel just the front edge of a countertop and leave side edges squared. Beveling only the front creates the visual effect you see without requiring extra work.

Do I need a bevel jig for grinding quartz?

A bevel jig can be helpful but isn’t required. Use a straight edge and pencil to mark your bevel line. Check bevel angle frequently with the straight edge when grinding freehand.

What grit sequence should I use to polish quartz?

Start with 50 grit to establish the bevel, then polish through 200, 800, 1500, and 3000 grit pads. Always begin polishing on the pad after the one used to create the bevel.

How smooth will the beveled edge be?

Proper polishing through fine grit pads results in a smooth, soft beveled edge. The edge should not feel sharp at all after polishing unless extremely narrow.


Adding a beveled edge to your quartz countertop can take the look to the next level. With the right angle grinder and diamond polishing pads, it is possible to DIY this project and get professional-looking results. Focus on creating a consistent 45 degree bevel angle. Move slowly through the polishing steps. A beautifully polished bevel transforms plain quartz into a premium, custom look for your kitchen or bath.
