How to Repair Quartz Countertop Scratch

Quartz countertops are popular in many homes due to their durability, aesthetic appeal, and low maintenance. However, like any surface, quartz can become scratched and damaged over time. Small scratches are unavoidable, but it is possible to repair and minimize the appearance of damaged areas on your quartz countertop. With some effort and the right materials, you can make your quartz counters look like new again.

What Causes Scratches on Quartz Countertops?

There are a few common causes of scratches and damage on quartz surfaces:

  • Cutting or chopping on the countertop – Using sharp knives directly on the quartz surface can slice into the material and leave cuts and scratches. Always use a cutting board.
  • Dragging heavy, coarse objects – Items like pots, pans, and appliances can scratch quartz when dragged across the surface. Lift objects to move them, don’t slide.
  • Impacts – Dropping heavy or pointed items on a quartz countertop can chip or scratch the material. Handle heavy objects carefully.
  • Harsh cleaners – Abrasive cleansers, scrapers, and scouring pads can damage and dull the surface over time. Use only quartz-safe cleaners.

How to Repair Minor Scratches on Quartz

Small, light scratches can often be minimized or removed from a quartz countertop using a few simple techniques:

Clean and Polish

  • First, clean the scratched area thoroughly with a quartz cleaner to remove any dirt or residue in the scratch.
  • After cleaning, apply a polish specifically made for quartz and work it into the scratch using small circular motions.
  • Polish helps smooth and fill scratches, restoring shine and luster.
  • For best results, use an electronic buffing pad or very fine (0000) steel wool to work the polish into the scratch.


  • For deeper scratches, you may need to sand down the surface. Use a 600 grit sandpaper wet/dry sheet.
  • Sand lightly in the direction of the scratch to flatten and minimize the mark. Check often to avoid over-sanding.
  • Follow with a polish to restore sheen after sanding.

DIY Repair Compounds

  • There are some DIY options to fill and repair scratched quartz countertops. These work best for minimal damage.
  • Try a homemade paste of baking soda and super glue – mix to form a thick paste, press into scratches, then wipe away excess.
  • Clear nail polish can also fill small scratches effectively. Apply a few thin layers, allowing drying time between coats.

Repairing Deeper Damage on Quartz Countertops

For more substantial chips, gouges, cracks, and damage areas, professional help may be required:

Professional Repair Services

  • Many quartz fabricators and installers offer repair services for more significant damage.
  • They have access to color-matched professional epoxy fillers to seamlessly repair chipped edges and cracks.
  • Some may even be able to refinish and repolish the damaged sections of your countertop.

Full Quartz Replacement

  • If damage is over a very large area, a full quartz countertop replacement may ultimately be needed.
  • Replacing just one section or area can be difficult to match with the surrounding undamaged quartz.
  • A professional installer can remove and replace the entire damaged countertop.

Preventing Future Scratches on Quartz

While you can repair existing damage, prevention is the best approach for keeping your quartz counters flawless:

  • Use cutting boards and trivets when chopping, cutting, or placing hot items on the surface.
  • Don’t drag or slide objects across the quartz. Lift items when moving them.
  • Clean with a gentle quartz cleaner – avoid abrasive products.
  • Apply a quartz sealer every 1-2 years to increase surface resistance.
  • Handle heavy appliances, pots, and objects carefully around the counters.

Frequently Asked Questions About Repairing Quartz Countertop Scratches

How deep of a scratch can you repair on a quartz countertop?

Very light surface scratches can often be polished out. Moderately deep scratches up to about 0.3 mm can be sanded and polished. But deeper gouges over 0.5 mm typically require a professional quartz repair service.

Does baking soda really repair quartz scratches?

Yes, baking soda mixed into a paste with super glue can be very effective for filling and repairing light to medium scratches. The adhesive properties fill the mark, while the baking soda mimics the color and texture.

What polish works best for fixing quartz countertop scratches?

Seek out polishes specifically formulated for use on engineered stone quartz surfaces. Brands like Gel-Gloss and IQ Quartz make high-quality polishing creams that help smooth and fill damaged areas.

Can you use automotive wet sandpaper to sand down scratches in quartz?

Yes, 400-600 grit wet/dry automotive sandpaper works well for gently smoothing and leveling scratched quartz counters. Remember to sand in the direction of the scratch to flatten the mark.

Will nail polish or super glue damage my quartz countertop?

When used in small amounts just to fill scratches, clear nail polish or cyanoacrylate (super glue) will not harm or stain a quartz surface. Just keep the application targeted only to the scratch.


Quartz countertops are very durable, but not totally immune to damage. With the right techniques and products, many scratches and marks can be minimized or repaired successfully. For deep gouges and extensive damage areas, seek professional help from a qualified quartz fabricator. And be sure to take preventative steps like using cutting boards and lifting heavy objects to keep your quartz counters looking pristine for years to come. With a little care and effort, you can restore the original beauty and luster to your valuable quartz countertop surfaces.
