How to Fix Quartz Countertop Chip

Quartz countertops are popular in many homes due to their durability, aesthetics, and low maintenance. However, like any solid surface, quartz can get damaged over time, especially around high-traffic areas like sinks and stovetops. Chips and cracks are common quartz countertop problems that occur from impact or excessive pressure. Fortunately, it is possible to repair quartz countertop chips and prevent further damage. This article will provide a step-by-step guide on how to fix quartz countertop chips and restore your countertops.

What Causes Chips in Quartz Countertops?

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

  • Impact damage – Dropping heavy objects like pots, pans, or appliances can easily chip quartz. Impact from blunt force is one of the most common causes of damage.
  • Thermal shock – Exposing quartz to sudden and extreme temperature changes, like pouring boiling water on a cold countertop, can cause cracks and chips from rapid expansion and contraction.
  • Settling or poor support – Installation issues like inadequate support or settling can lead to stressed areas that chip over time.
  • Excessive pressure – Applying too much localized pressure, by standing on your countertops for example, can cause chips and cracks.

How to Repair a Small Chip in a Quartz Countertop

For small chips less than 1⁄4 inch, you can often complete a DIY repair:

Clean and Dry the Area

First, clean the damaged area with a nonabrasive cleaner and water. Make sure the area is completely dry before repairing the chip. Residual moisture can impact adhesion.

Sand the Chips

Use 150-grit sandpaper to smooth and deburr the chipped edges. This will help the repair blend better. Take care not to sand too aggressively.

Fill with Epoxy

After sanding, fill the void completely with an epoxy adhesive formulated for countertops. Cover the surrounding area to help bond the patch.

Optional – Add Colorant

If needed, add a quartz colorant to the epoxy to help match the color. Test on scrap material first to match the tone.

Level and Remove Excess

Once filled, use a plastic putty knife to level and remove any excess epoxy. Wipe the area completely clean.

Cure Per Manufacturer Instructions

Follow the epoxy curing times. Most require 24 hours before sanding and polishing.

Sand and Polish

Once fully cured, use 150 to 600 grit sandpaper to blend and smooth the repair. Finish by polishing with a buffing compound.

With small chips, this DIY epoxy repair can restore your quartz countertop’s appearance and prevent further damage.

Repairing Larger Chips and Cracks in Quartz

For larger chips over 1⁄4 inch across or cracks over 3 inches, a professional repair is usually best for proper structural repair. A full professional process involves:

Clean and Prepare the Area

Clean debris from the damaged section. Use a diamond blade saw to cut a clean edge around larger chips.

Make a Template

Create a template of the damaged section to cut a precisely fitted patch. Use heavy paper or thin cardboard.

Cut the Patch Piece

Use the template to cut a replacement piece from a quartz scrap or remnant. Cut edges should be smooth.

Adhere the Patch

Apply adhesive like polyester resin to attach the new quartz patch piece. Use clamps and weight for compression.

Level and Sand Edges

Once adhered, use a belt sander or grinding pad to level the patch and blend edges. Avoid over-sanding.

Polish Surface

Finally, polish the surface using wet sanding and buffing pads up to 3000 grit for a smooth finish.

Professional quartz repair contractors have the tools, adhesives, and training to make damaged areas structurally sound and visually blended. While an investment, their work can make the countertop look like new again.

How to Prevent Chips and Cracks in Quartz Countertops

Preventing damage in the first place is preferable to repairing quartz countertops. Here are some tips:

  • Use cutting boards and hot pads to protect surfaces. Never cut or place hot pots directly on quartz.
  • Clean spills quickly to avoid moisture damage. Use a pH-neutral stone cleaner.
  • Avoid excessive impact force and pressure on your countertops. Don’t stand or sit on them.
  • Have support and overhangs installed properly according to manufacturer specifications.
  • Inspect for loose or shifting areas around sinks and backsplashes and have them secured.
  • Consider adding an additional sealant layer for added protection on heavy use areas.

With proper care and precautions, it is possible to keep quartz countertops smooth and damage-free for years before repairs become necessary.

FAQs About Repairing Quartz Countertop Chips

Can I repair a chip in my quartz countertop myself?

Yes, small chips less than 1⁄4 inch can often be repaired with a DIY epoxy kit. Sand the chip smooth, fill with dye-matched epoxy, and then sand and polish once cured. Larger chips are best left to professionals.

What is the best adhesive for quartz countertop chip repair?

Polyester-styrene or methacrylate-based adhesives are best for structural quartz repairs. Colored epoxies are ideal for small DIY chip fills. Always use adhesives formulated for countertops.

Should I completely replace a damaged quartz countertop?

Complete replacement is usually only necessary if damage is very extensive. Localized chips and cracks can almost always be repaired by a professional. Repair is often much more affordable than a full replacement.

Can any epoxy be used to fill quartz chips?

No, it’s important to use an epoxy designed for countertop use. General construction epoxies lack UV resistance and can yellow over time. Purchase a specialized countertop repair epoxy.

Is it possible to match the color when repairing a quartz chip?

In most cases, yes. Adding a small amount of colorant to clear epoxy can achieve excellent color matching results. Always test on a quartz remnant first. Professional repairs can blend seamlessly.

How long does a quartz chip repair take to cure?

Cure times vary by products used but usually 24-48 hours. DIY epoxy kits need about 24 hours before sanding and polishing. Adhesives used by professionals may require even longer to fully harden and structurally bond.

Can I use nail polish or super glue to fix a quartz chip?

No, products like nail polish, super glue, and wood filler are unsuitable. They lack strength, cause discoloration, and do not properly adhere. Always use a countertop-specific adhesive like epoxy or resin.


Quartz countertop chips happen but professional repair or quality DIY fixes can often restore surfaces to like-new condition. To prevent chips, take care to protect your countertops from impact damage and localized pressure points. With some basic repair knowledge and preventative practices, it is possible to keep quartz counters pristine and damage-free for many years before any major restoration is needed. Regularly inspecting and addressing minor chips as they occur prevents larger cracks from developing.
