How to Repair Scratches on Quartz Countertops

Quartz countertops are popular options for kitchens and bathrooms because of their durability, low maintenance, and stylish appearance. However, like any surface, quartz can become scratched over time. The good news is that there are methods to repair superficial scratches and restore the look of your quartz countertops.

Assessing the Damage

Not all scratches on quartz require extensive repair. Superficial scratches may fade over time or can be addressed with simple polishing. Examine the scratch closely to determine how deep it is:

  • Surface scratches – These light scratches only affect the surface sealant of the quartz. They can often be removed with polishing.
  • Deeper scratches – If the scratch catches your fingernail or you can feel a groove, the damage likely goes beyond the sealant. You will need more extensive repair methods.
  • Chips and gouges – Major damage that takes out pieces of the quartz will require professional repair.

Cleaning and Polishing for Minor Scratches

For light surface scratches, start by cleaning the area:

  • Use a soft cloth and mild non-abrasive soap and water to clean the countertop. Rinse well.
  • Avoid scrubbing pads or abrasive cleaners which can worsen scratches.

After cleaning, apply a quartz polishing kit according to package directions:

  • Many kits come with a buffing pad and special polishing compound.
  • Work in a circular motion over scratches to wear down the edges.
  • Take care not to apply too much pressure, which can create new scratches.
  • Rinse the surface after polishing and buff dry.

The scratches may not disappear completely, but polishing can significantly improve their appearance.

Repairing Deeper Scratches

For more severe scratches, you will need to use filling and resurfacing techniques:


To prepare the scratched area for repair:

  • Carefully smooth and shape the scratch using 150 grit sandpaper on a sanding block. Take care not to widen the scratch.
  • Gradually step down the grit, ending with 220-400 grit paper to feather the edges.
  • Clean away sanding dust. The area should be completely smooth.

Applying filler

Two options for filling deeper scratches are:

  • Quartz filler – Specialty filler products designed for quartz countertops will provide the best color match. Apply in thin coats according to package directions.
  • Clear epoxy resin – Can also be used to fill scratches in quartz. Mix the resin and hardener as directed and fill the scratch just short of overflowing.

Once the filler has fully cured, sand flush using 400 grit paper. Clean the area well.


The final step is applying new sealant to the repaired scratch:

  • Use a quartz-specific sealer for the best bond. Flow it over the repair according to directions.
  • Allow to fully cure for 24-48 hours.
  • Buff gently with a soft cloth to blend with the surrounding countertop.

With proper products and techniques, you can successfully repair scratches and restore the beauty of your quartz countertops. If damage is too severe for DIY repair, contact a professional countertop fabricator.

Frequently Asked Questions

Can all scratches on quartz be repaired?

Minor surface scratches can often be minimized with polishing. Deeper scratches may require sanding and filling. But very deep gouges or chunks of missing quartz can be difficult or impossible for an amateur to repair. Know your limits and call a pro if damage is beyond your skills.

Will the repair be noticeable?

With shallow scratches, polishing can nearly erase signs of damage. For deeper repairs, results will depend on your skill level. A professional refinisher will have the best chance of making the repair blend seamlessly. But done properly, a DIY quartz repair can be quite subtle.

Is there a quick fix for quartz scratches?

Unfortunately, no. True repair involves methodically smoothing, filling, sealing and polishing. Quick fixes like rubbing compounds may slightly improve the look but don’t actually repair the scratch. Proper repairs take time but are worthwhile to restore the countertop’s appearance.

Should I try to buff out scratches myself first?

It’s fine to try polishing minor scratches yourself before calling in a professional. Use a quartz polish, not merely a general stone polish, for the best results. But be careful not to apply too much pressure or create new scratches. Know when to call for expert help with deeper damage.

How long will my quartz countertop repair last?

Quartz repairs should last indefinitely if done properly. The filler and sealant bond securely in the scratch for a lasting repair. However, quartz can become re-scratched over time with normal wear and tear. Proper care will help your countertops look their best for years.


While scratches in quartz countertops are unsightly, don’t despair. Minor damage can often be minimized through simple polishing. For deeper scratches, sanding, filling, and resealing can make them far less noticeable. With some time and effort, you can restore your quartz countertops’ original smooth appearance and have them looking like new again. Just be sure to use specialty quartz products and proper techniques for repairs that will stand the test of time.
