How to Repair a Small Chip in Quartz Countertop

Quartz countertops are durable, beautiful, and easy to maintain. However, like any countertop material, they can get the occasional chip or scratch. Small chips in a quartz countertop are usually just a cosmetic issue and do not require a full replacement of the countertop. With the right materials and techniques, you can repair a small chip and restore your quartz countertop’s flawless appearance.

What You’ll Need

  • Clear epoxy resin
  • Colored epoxy pigments (to match countertop color)
  • Plastic spreader or putty knife
  • Sandpaper (120 to 220 grit)
  • Clean cloths
  • Tape (if needed)

Prep the Chip

Before repairing the chip, you’ll need to properly clean and prepare the area:

  • Clean the countertop around the chipped area with soap and water to remove any dirt or debris.
  • Let it dry completely.
  • Use sandpaper to rough up the surface inside the chipped area – this helps the epoxy resin adhere properly.
  • Wipe away any dust with a clean cloth.
  • If the chipped area is near an edge or seam, tape off the surrounding surface to keep the epoxy contained as it cures.

Mix and Apply Epoxy Resin

  • Mix a small amount of clear epoxy resin according to package directions.
  • Add colored pigment and mix thoroughly until you achieve the color match of your quartz countertop.
  • Pour the colored epoxy into the chipped area up to the level of the surrounding quartz.
  • Use a plastic spreader to spread the epoxy evenly across the chipped section.
  • Push the epoxy into any cracks or holes to fill completely.
  • Add more epoxy if needed to build up level with the surrounding surface.

Let Cure and Sand

  • Allow the epoxy resin to fully cure according to package directions. This usually takes 6-12 hours.
  • Once cured, use 120 grit sandpaper to smooth the epoxy level with the quartz countertop.
  • Finish by sanding with 220 grit paper to blend repair seamlessly.
  • Wipe away any dust with a clean, dry cloth.

The sanded epoxy repair should now appear level and indistinguishable from the surrounding quartz. You’ve successfully repaired the chip! Enjoy your quartz countertop’s renewed flawless finish.

FAQs about Repairing Quartz Countertop Chips

What kind of epoxy should I use?

Use a clear epoxy resin made specifically for countertops. Hardware store epoxy putties usually dry too soft and opaque. Get an epoxy made for smooth, glass-like finishes.

Should I tape off the area around the chip?

It’s a good idea to use painter’s tape around a chip near the edge of a countertop. This contains the epoxy as it self-levels and cures. Remove the tape after about 10 minutes while the epoxy is still pliable.

How do I match the quartz color when adding pigment?

Mix a very small amount of epoxy first without any pigment. Then add tiny amounts of colorant and mix well to closely match the quartz. Mix up a larger batch once you achieve the right color.

Can I use the countertop while the epoxy cures?

It’s best not to use the area for 6-12 hours as the epoxy fully cures. Avoid any water or direct pressure on the repair during this time.

Should I seal the repaired area afterwards?

Sealing is not necessary. Quality quartz epoxy is formulated to cure hard and waterproof to match the factory finish.


Repairing a small quartz countertop chip takes just a few simple steps. With the right materials and techniques, you can achieve an economical repair that looks seamless. Just be sure to properly clean and sand the area first, color-match the epoxy, apply smoothly, and allow proper cure time. Your once-damaged countertop can look pristine again. Carefully repairing chips as they occur prevents them from growing larger over time and avoids a costly full countertop replacement down the road.
