Can a Chip in a Quartz Countertop be Repaired?

Quartz countertops are durable and beautiful, but chips and cracks can occur. Thankfully, minor chips in a quartz countertop can often be repaired. Here is a comprehensive guide on repairing chips in quartz countertops.

What Causes Chips and Cracks in Quartz?

There are a few common causes of chips and cracks in quartz countertops:

  • Dropping a heavy object on the countertop – Pots, pans, and other heavy, hard objects can chip quartz if dropped with force.
  • Impact from a hard object – A knock or bump from appliances, tools, etc. can also chip the surface.
  • Settling or movement – If the countertop installation is improper or the home/building settles, it can cause stress cracks.
  • Thermal shock – Exposing quartz to extreme temperature swings can cause chips and cracks due to thermal expansion.
  • Manufacturing defects – Rarely, imperfections in the material or fabrication process can make chips and cracks more likely.

Assessing Quartz Chip Damage

When you notice a chip in your quartz countertop, assess the size and depth of the damage:

  • Minor chips – Smaller than a dime, only affecting the top layer.
  • Moderate chips – Larger than a dime, affecting a deeper layer.
  • Major chips – Exposing the substrate below the quartz layer.
  • Cracks – Fissures of any size in the quartz.

Minor chips can often be repaired, while major chips and cracks may require a professional fabricator.

Repairing a Minor Chip in Quartz

Here are the steps for repairing a small quartz chip yourself:

1. Clean and Dry the Area

Use a nonabrasive cleaner and soft cloth to clean the area, removing any dirt or debris from the chip. Dry thoroughly.

2. Apply Epoxy Filler

Choose an epoxy resin made for countertops. Tint the epoxy if needed to match the quartz color. Fill the chip just above the surface level.

3. Smooth and Level the Epoxy

Once dry, sand the epoxy gently with fine sandpaper until flush with the countertop. Wipe away dust.

4. Buff and Polish

Use a polishing pad and very fine polishing compound to buff the repaired area. Polish until smooth and shiny.

5. Seal and Protect

Apply a penetrating sealant made for quartz to protect the repair and make cleaning easier.

With this process, you can fill minor quartz chips for a seamless, polished look.

When to Call a Professional

For moderate or major chips, or for cracks of any size, it’s best to call a professional fabricator. They have the tools and expertise to repair or replace quartz.

Signs you may need a pro:

  • The chip exposes the substrate under the quartz.
  • The damage is wider than a quarter.
  • It affects a large area.
  • Any crack is present.
  • The color/finish can’t be matched.
  • The area can’t be smoothed or polished.

Professional repairs can be pricey but are often less than full replacement. Some pros can even do on-site chip repairs.

Preventing Damage

To avoid chips and cracks in your quartz:

  • Use cutting boards and hot pads. Never cut or place hot items directly on the quartz.
  • Clean spills quickly to avoid moisture damage.
  • Avoid bumping the edges with appliances. Use padding/rollers.
  • Support overhangs properly and seal seams to prevent cracks.
  • Have professionals install and remove sinks or cooktops to avoid damaging the quartz.

With proper care, quartz countertops can remain resilient for many years in your kitchen or bath. But minor chips are common and can be repaired by a pro or sometimes DIY. Know when to repair vs. replace damaged quartz to keep your counters looking pristine.

Frequently Asked Questions About Repairing Quartz Chips

Can I repair a chip in my quartz countertop myself?

Minor chips smaller than a dime can often be repaired yourself using filler epoxy, sanding, polishing, and sealing. For larger chips or any cracks, it’s best to hire a pro.

How do you color-match the epoxy resin to the quartz?

Get a small sample chip of your quartz color. Take it to a hardware store to color-match and tint the two-part epoxy filler. Mixing pigments into clear epoxy can achieve the color.

What is the best way to smooth and polish the epoxy repair?

Let the filler cure fully, then sand flush with fine 220-400 grit paper. Buff with a polishing pad and compound, cleaning residue as you work. Finish by polishing to a uniform sheen.

Can I use superglue, nail polish, or porcelain filler to repair a chip?

No, those won’t work. Use an epoxy resin formulated for countertops. It will bond properly and stand up to daily use. Match the tint.

How long does the epoxy filler repair last?

Done properly, an epoxy chip repair can last for years with proper care. Avoid abrasive cleaners and be sure to use cutting boards. Reseal annually.


Minor chips in quartz counters are common but can be an eyesore. Often you can repair small chips yourself with tinted epoxy filler, patience, and polish. For best results, address any chips right away before moisture creeps in and causes greater damage. With some DIY techniques, you can avoid replacing the entire countertop. For major repairs, count on a trained fabricator to restore your quartz to its original beauty.
