How to Fix a Chip on Quartz Countertop

Quartz countertops are durable and low-maintenance, but chips and cracks can still occur. Fixing a chip in a quartz countertop is possible with the right materials and techniques. Here is a step-by-step guide on how to fix a chip on a quartz countertop.

Assessing the Damage

The first step is to assess the size and depth of the chip. Small surface chips may be repaired with a coloring kit, while deeper chips will require a more intensive repair process.

  • Examine the chip under good lighting. Use a ruler or tape measure to determine the length and width of the chip.
  • Check if the chip extends below the surface by running your fingernail over it. A deep chip will catch your nail.
  • Identify the color and pattern of your quartz countertop. This will help match repair materials.

Cleaning and Prepping the Area

Proper cleaning and prep work ensures a successful chip repair.

  • Clean the area thoroughly with a granite cleaner or mild soap and water. Rinse and dry completely.
  • Use painter’s tape to mask off the area around the chip. This keeps the repair materials contained.
  • Be sure the chip and surrounding countertop is completely dry before repairing.

Repairing a Surface Chip

For minor surface chips:

  • Select a quartz color repair kit that closely matches your countertop. Kits contain colored resins to fill chips.
  • Mix the resin according to kit directions and use a plastic putty knife to fill the chip. Overfill slightly.
  • Allow the resin to cure fully, then sand flush with the countertop. Start with 150 grit sandpaper, then finish with 220 grit.
  • Clean the sanded area and apply several coats of clear sealant, allowing drying time between coats.
  • Remove the painter’s tape and clean the countertop once more. The chip should now blend with the surface.

Repairing a Deep Chip

For deeper chips:

  • Clean loose edges of the chip with acetone. Let dry completely.
  • Mix two-part epoxy adhesive and fill the chip just above the surface, mounding slightly.
  • Allow the epoxy to cure fully, then sand flush as above, finishing with 220 grit paper.
  • Clean and seal as above. The epoxy will be close to the quartz color, but resin can be added to blend the repair.

Preventing Future Damage

To avoid more chips in your quartz:

  • Use cutting boards rather than cutting directly on the surface.
  • Don’t place hot pans from the stove or oven directly on the countertop. Always use trivets.
  • Clean spills promptly to avoid stains and damage to the surface seal.
  • Handle the countertop gently and avoid hard impacts from heavy objects.

With the right materials and techniques, it is possible to repair chips in quartz countertops. Proper prep work, coloring, sanding, and sealing helps blend repairs into the surface. Take steps to prevent damage in the future. Your countertop can look like new again after a chip repair.

Frequently Asked Questions About Fixing Chips in Quartz Countertops

Can I repair a chip in my quartz countertop myself?

Yes, with the right materials, you can repair minor chips and some deeper damages yourself. Color matching kits, epoxy adhesives, and sealants can help you blend repairs into the countertop.

What is the best adhesive for quartz countertop chip repair?

Opt for a two-part epoxy adhesive formulated for stone repairs. The epoxy will bond well and cure solidly to fill deeper chips properly.

Should I use resin or epoxy to fix a quartz chip?

Minor surface chips can be filled with colored resin compounds found in chip repair kits. But deeper chips below the surface will require epoxy adhesives for the strongest repair.

What grit sandpaper is best for quartz chip repairs?

Use 150 grit sandpaper to level and smooth repairs flush with the surface, then 220 grit to finely blend and polish the area. Always finish sanding with the smoothest paper.

Can I use concrete repair products on my quartz countertop?

No, concrete repair compounds are meant for porous materials and will not bond effectively to non-porous quartz. Use only epoxies and resins made for natural stone repair.

Should I seal a repaired quartz chip?

Yes, applying a quality stone sealer over the repair is highly recommended. This fills any pores and provides an extra layer of protection to prevent staining.

How can I prevent chips and cracks in my quartz countertops?

Use cutting boards, trivets and heat pads. Clean spills quickly. Avoid direct impacts from heavy objects. Handle the surface gently to prevent chips and cracks.


Fixing a chip or crack in quartz countertops is very doable with the proper materials and techniques. Assessing the damage, proper prep work, using quality epoxy and resin fillers, sanding, sealing and color matching helps create an excellent repair that blends into the surface. With some care and DIY skills, your quartz countertop can look pristine again after suffering a chip or crack. Be sure to take steps to prevent future damage too.
