How to Repair a Chip in Quartz Countertop


Quartz countertops are a popular choice for many homeowners due to their durability, low maintenance, and stylish appearance. However, like any surface, quartz can become damaged over time, especially around high-traffic areas such as near the sink or stove. Chips and cracks in a quartz countertop not only detract from its aesthetic appeal but can also allow moisture and bacteria to seep underneath and cause more extensive damage if left unrepaired. Thankfully, there are several effective methods for repairing a chip in a quartz countertop, allowing you to restore its flawless look.

Assessing the Damage

Before attempting to repair a chip or crack in your quartz countertop, first thoroughly examine the area to determine the severity of the damage. Small chips, characterized by minor surface flaws under 1/4 inch in diameter, can often be fixed using basic DIY methods. However, larger chips that penetrate deep into the slab, extend across multiple areas, or result in loose cracked pieces will likely require professional help.

Take note of the chip’s size, depth, and location. Also check for any internal cracks radiating from the chip that are not visible from the surface. Any cracks present under the countertop’s surface can spread over time if not properly repaired.

Cleaning and Prepping the Area

Once you have assessed the chip, clean and prepare the damaged section before making any repairs. Remove any debris, food, grease or dirt buildup by gently scrubbing with a soft cloth, mild soap and warm water. Avoid harsh cleaners or abrasive pads that could further scratch the surface.

Thoroughly rinse and dry the area after cleaning. You want the quartz to be completely free of any residue to allow the repair products to properly adhere. Carefully sand down any raised edges around the chip using fine grit sandpaper. This helps level the area for a smoother finish. Wipe away all dust with a dry cloth after sanding.

DIY Repair Options for Small Chips

For minor chips less than 1/4 inch, these simple DIY fixes can often remedy the flaws:

Clear Epoxy Kit

  • Purchase a quartz countertop repair epoxy kit. Look for a fast-drying, clear formula designed specifically for quartz.
  • Mix the epoxy resin and hardener according to kit directions and apply using included tools.
  • Fill the chip just above the surface, allowing it to dry completely.
  • Once hardened, sand flush with the countertop and polish area.

Colored Wax Sticks

  • Select a wax filler stick in a color that matches your quartz.
  • Warm stick with a hair dryer and rub over the flaw to fill it.
  • Smooth with plastic card and wipe away excess wax.
  • Reapply if needed until the chip blends with countertop.

Cyanoacrylate Adhesive

  • Place a small dot of cyanoacrylate glue in the chip and allow to penetrate cracks.
  • Fill up the chip just above the surface with more glue and let fully harden.
  • Sand down excess adhesive until smooth and flush.

Be sure to follow all product instructions carefully. Test products first on inconspicuous areas to ensure color match and compatibility with your specific quartz material.

Professional Repairs for Larger Damage

For more substantial chips larger than 1/4 inch or cracks over 1 inch, professional help is typically required. DIY remedies are unlikely to restore structural integrity or appear seamless on significant damage. Qualified countertop fabricators have products and techniques to re-fill and bond large flaws for a perfect repair. Common professional options include:

Color-Matched Filler

  • The chip is cleaned out and filled with an adhesive color-matched filler.
  • Once dried, the area is sanded smooth and re-polished.

Seamless Patch

  • Damaged quartz is precisely cut out and removed.
  • A new quartz patch, color-matched to the existing slab, is professionally cut and secured in place with adhesive.
  • The edges are bonded and treated for an invisible repair.

Full Slab Replacement

  • For extensive damage spanning over 25% of the total surface, a full quartz countertop replacement may be recommended.
  • The entire damaged slab is removed and replaced with a new, identical quartz piece.

Be sure to hire an experienced professional specializing in quartz repair. Get a few quotes to compare pricing. Typical costs range from $100 – $500 depending on the repair method.

Preventing Future Damage

To help prevent chips and cracks in your quartz countertops in the future:

  • Use cutting boards and hot pads when food prepping. Never cut or place hot items directly on the quartz.
  • Avoid dropping heavy objects that may chip or crack the surface.
  • Clean spills quickly to prevent stains which can lead to chipping when attempting to remove.
  • Install a sink mat or padding underneath accessories to absorb impacts.
  • Apply a quartz sealant every 1-2 years for added protection.

With proper care and regular maintenance, it is possible to keep your quartz countertops in flawless condition for years. But even if some damage does occur over time, know there are great options to make repairs and restore your countertop’s original beauty. Just be sure to address any chips or cracks right away before they worsen or spread.

Frequently Asked Questions About Repairing Chips in Quartz Countertops

What are the signs of a minor chip versus major damage in a quartz countertop?

Minor chips are usually small, shallow surface flaws less than 1/4 inch in size that do not affect structural integrity. Major damage consists of chips larger than 1/4 inch deep, cracks exceeding 1 inch, internal fractures not visible on the surface, or multiple damaged areas clustered together.

Is it ok to make a DIY repair on a rental property quartz countertop?

It is best to consult your landlord first before attempting to repair chips or cracks in rental property. Most DIY methods involve adhesives that may damage the countertop worse if removed later. Landlords often prefer using authorized professionals for repairs.

Should I try to glue a broken off quartz countertop chip back into place?

It is not recommended to try gluing a broken loose chip back in place. The structural integrity will be compromised, and the repair will likely fail quickly. It is better to have a professional cut out the damaged section and seamlessly replace it with a color-matched quartz inlay.

What color wax filler stick should I use on my white quartz countertop chip?

For a white quartz countertop, choose a wax filler stick in a sheer neutral tone rather than pure white, which can stand out. Slightly beige or ivory shades tend to blend best for small flaws on white quartz surfaces. Always test on an inconspicuous spot first.

How soon can I use my quartz countertop after a professional chip repair?

Cure times vary, but most professional chip repairs require at least 24 hours of drying time before regular use. Avoid submerging the area in water or applying heavy impacts for at least 2-3 days. Ask your fabricator about specific cure times for the products used.


In summary, chips and cracks in quartz countertops should be promptly repaired to maintain beauty, value, and functionality. Assess the severity of damage to determine whether a DIY or professional approach is best. For minimal flaws under 1/4 inch, epoxy kits, colored wax sticks or adhesives provide easy fixes. Large chips over 1/4 inch across multiple areas usually call for expert repair methods. With some care and effort, it is possible to make chips in quartz countertops virtually disappear. Just be sure to address any damage right away before it worsens. Your countertop can look like new again with the right repair techniques.
