How to Fix a Nick in a 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. Small nicks and scratches are common and can occur from cutting or placing hot items on the countertop. The good news is that minor damages can often be repaired at home without having to replace the entire countertop. This article will provide step-by-step instructions on how to fix a nick in a quartz countertop.

Assessing the Damage

The first step is to inspect the nick and determine the severity. Small surface scratches or chips less than 1/8 inch deep can often be repaired with a little effort. However, deeper nicks exposing the substrate below the quartz will require professional help.

To check the depth, catch your fingernail on the edge of the damaged area. If your nail hangs up, it is likely a surface scratch that you can repair yourself. Use a ruler or measuring tape if needed to measure the actual depth.

Cleaning and Prepping the Area

Before making any repairs, thoroughly clean the area with a nonabrasive cleaner and soft cloth. This will remove any dust or debris so the repair materials can properly adhere.

Be sure to dry the area completely after cleaning. Use a hairdryer if needed to speed up drying time.

Filling the Nick

For small, shallow surface damages, a quality quartz repair kit can be used to fill nicks and prevent further chipping. These kits contain an adhesive filler compound that you mix and apply to the damaged spot with a putty knife. The filler hardens to match the durability and color of the original quartz.

Follow the product instructions carefully when mixing the epoxy filler. Only make enough for the repair area, as the compound will begin hardening quickly once mixed. Press the filler firmly into the nick, overfilling slightly.

Allow the filler to cure fully before moving on to sanding and polishing. This usually takes about 24 hours. The kit should include instructions on cure times.

Sanding and Polishing

Once fully cured, use 120 to 220 grit sandpaper to smooth and shape the filler area. Sand in small circular motions. Avoid sanding too aggressively so you don’t create any new low spots.

Move up to a 400 or 600 grit sandpaper for the final smoothing. Wipe away all sanding dust with a dry cloth after each sanding.

For polishing, apply a dollop of mineral oil, beeswax polish, or quartz polish to a soft cloth. Rub the polish in circular motions over the repair area to blend and restore the luster. Remove any excess polish with a clean dry cloth.

Preventing Future Damage

To help prevent future nicks and scratches:

  • Use cutting boards and hot pads when preparing food on quartz.
  • Don’t place extremely hot pans or dishes directly on the quartz.
  • Clean spills promptly to avoid staining. Quartz is fairly stain resistant but not 100% impervious.
  • Avoid using abrasive cleaners or scouring pads which can dull the surface over time.
  • Consider applying a quartz sealer every 1-2 years to boost protection.

With proper care and these repair tips, you can keep your quartz countertops looking like new for years. Contact a professional stone restoration company for repairs beyond DIY methods.

Frequently Asked Questions

Is fixing a quartz countertop nick something I can do myself?

Yes, minor surface nicks and scratches less than 1/8 inch deep can often be repaired at home using a quartz repair kit with filler and polish. Deeper damage exposing the substrate will require a professional.

What should I use to clean the area before repairing?

Use a soft cloth with a nonabrasive cleaner like dish soap and water to thoroughly clean the area. Avoid harsh chemicals. Completely dry the surface before applying any filler.

How long does the quartz filler need to cure before sanding?

It depends on the product used but typically around 24 hours. Always follow the manufacturer’s instructions for cure times to ensure proper hardening. Sanding too soon can pull the filler out of the nick.

Can I use automotive scratch repair products on quartz?

No, auto body fillers and compounds are designed for paint repair. Use a stone repair product made specifically for quartz and other solid surfaces. The filler must match the strength and durability of quartz.

Is there anything I can apply to help prevent future nicks and scratches?

Yes, consider applying a penetrating quartz sealer every 1-2 years. Sealers provide an added layer of protection against damage from knives, spills, and daily wear and tear. Just be sure to use a product made for quartz.


Fixing a nick or scratch in quartz countertops is often a DIY project if the damage is minor. Assess the depth of the damage first. Superficial surface chips can be filled with a quartz repair compound, sanded smooth, and polished to restore the look. Prevent future nicks by using cutting boards, taking care with hot items, promptly cleaning spills, and applying a sealer periodically. With the right supplies and techniques, you can keep your quartz counters pristine. Contact a pro for deep repairs or full replacement if needed.
