How to Fix Dent in Quartz Countertop

Quartz countertops are durable and low-maintenance, but not immune to damage. Dents and chips can occur over time. Fortunately, there are several effective methods to repair minor dents in quartz. With a little time and effort, you can restore the beautiful, flawless surface of your quartz countertop.

What Causes Dents in Quartz?

Quartz is made from ground natural stone and resin. This makes it very hard and resistant to scratches. However, quartz can still be susceptible to dents from impact or excessive pressure. Common causes of dents include:

  • Dropping heavy objects like pans, appliances, or tools
  • Applying too much force when working on the countertop
  • Allowing objects with sharp edges to impact the surface
  • Using the countertop as a cutting board

Dents in quartz are usually minor indentations in the surface. Deep cracks or chips that expose the substrate underneath require professional repair. But small dents can often be fixed with do-it-yourself methods.

How to Repair a Dent in Quartz Countertop

Here are the best techniques for DIY dent repair on a quartz countertop:

Gather Supplies

You’ll need a few basic supplies:

  • Rags
  • Acetone or denatured alcohol
  • Putty knife or razor blade
  • Superglue or epoxy resin
  • Mixing container and sticks (for epoxy)
  • Sandpaper (220 to 400 grit)
  • Microfiber cloths
  • Buffing pad

Choose a high-quality epoxy resin designed for countertops. Hardware stores carry products such as Akemi quartz countertop repair kits that include everything needed.

Clean the Area

Use acetone or alcohol on rags to thoroughly clean the area and remove any waxes or debris from the dent. Allow it to dry completely.

Fill the Dent

Squeeze a small amount of superglue into the dent and allow it to cure per the product directions, usually about 5 minutes. Apply more glue in thin layers to slightly overfill the dent.

Alternatively, mix a small batch of epoxy resin per the product instructions. Fill the dent fully with the epoxy using a putty knife or razor blade. Make sure to smooth it flush with the surrounding quartz.

Allow Proper Curing Time

It’s crucial to allow the superglue or epoxy to fully cure before sanding. This can take 30 minutes for superglue or up to 24 hours for epoxy. Refer to the product label. Rushing this step can pull the filler out of the dent.

Sand the Area

Once fully cured, start sanding the filled dent with 220 grit sandpaper using gentle circular motions. Gradually step up to 400 grit to smooth the texture.

Clean and Polish

Clean the sanded area well with a microfiber cloth. Use a buffing pad and quartz countertop polish to buff the surface for a shine.

Check for Smoothness

Finally, run your hand across the area to ensure it feels completely smooth and even with the surrounding quartz. Apply additional thin layers of glue or epoxy if any unevenness remains. Repeat sanding and buffing.

Preventing Future Dents

To help avoid dents in quartz countertops:

  • Use cutting boards for food prep
  • Install padding under appliances
  • Avoid dropping or dragging heavy objects
  • Apply wax to enhance surface protection
  • Handle the countertop gently during daily use

With proper care and these repair techniques, minor dents in quartz countertops can be smoothed away to restore their flawless look. But deep cracks or large chips should be repaired by a countertop professional.

Frequently Asked Questions

How do you fix a chip in a quartz countertop?

Small chips can be repaired the same way as dents. Clean and fill with superglue or epoxy, allow curing, then sand and polish. Deeper chips may need the filler applied in layers over several days for the best results.

What is the best filler for quartz countertop repairs?

An epoxy resin formulated for quartz countertop repair will provide the most durable and long-lasting fill results. Superglue can also work for minor flaws. Avoid wood or drywall filler.

Should you use heat on a quartz countertop dent?

No, avoid using direct heat like a blow dryer or heat gun to try to pop out dents. The abrupt temperature change can damage the structural integrity of the quartz.

Can you buff out scratches in quartz countertops?

Light superficial scratches may be minimized by buffing and polishing, but don’t buff too aggressively on deep scratches. Filling with resin and sanding is better for deeper flaws.

Does quartz stain easily?

Quartz resists stains very well compared to other countertop materials. But prolonged exposure to strongly colored substances (like wine, coffee and juice) can cause staining over time if spills aren’t cleaned promptly.


Dents and chips in quartz countertops are fairly common but can be repaired without needing a countertop replacement. With a few basic supplies and techniques, minor dents can be filled and blended to restore the countertop surface. Just remember to thoroughly clean the area first, properly fill and cure the resin, sand smooth, and buff to polish. Paying attention to preventative care will also help avoid damage. With a little effort, your quartz countertop can look pristine once again.
