How to Fix a Scratch on Quartz Countertop


Quartz countertops are popular in many homes due to their durability, stain resistance, and stylish appearance. However, like any surface, quartz can get scratched and damaged over time. Small scratches are inevitable, but deep gouges and chips can be unsightly and negatively impact your beautiful countertop. Fortunately, there are several effective methods to repair and fix scratches on quartz.

In this comprehensive guide, we will cover the best steps for fixing various types of scratches and damage on quartz countertops. With a little bit of effort, the right materials, and proper techniques, you can make those annoying quartz scratches disappear. Let’s get started!

Evaluate the Severity of the Scratch

The first step is to assess the scratch on your quartz countertop and categorize it into one of three levels:

Light Surface Scratches

These are minor scratches that have not cut through the surface layer of the quartz. You can catch your fingernail on them and they appear as thin white lines across the surface. These are the easiest to remove.

Deeper Scratches

Medium scratches that have cut deeper into the quartz but have not exposed the filler underneath. They are often wider and more visible than surface scratches.

Gouges and Chips

Deep gashes where the quartz layer is penetrated and the filler material underneath is exposed. These require the most work to repair.

Properly identifying the level of damage will determine which fixing method to use. Take a close look under bright lighting from multiple angles. Run your fingers gently across the length of the scratch to feel if it is smooth or catches as you go along.

Clean the Quartz Surface

Before attempting to fix any scratches, thoroughly clean the area with a mild nonabrasive cleaner. This will remove any dirt, dust, oil, and debris that may have settled inside the scratches.

Make sure the quartz is completely dry before moving onto the next steps. Any moisture left in the scratches can affect the adhesion of repair products.

Light Surface Scratches:

Here are the best options for fixing light surface scratches on quartz:

Baking Soda and Water Paste

Make a paste with baking soda and water and use a soft cloth to gently rub it over the scratch marks. The fine yet abrasive texture of baking soda will buff out and minimize the visibility of superficial scratches. Rinse with water and dry it well.

Mr. Clean Magic Eraser

These melamine foam cleaning pads act as a very mild sandpaper to wear down light scratches. Run it over the marks using moderate pressure and a circular motion. This is an easy fix that can significantly reduce the appearance of fine scratches.

Automotive Buffing Compound

Use a high quality automotive polishing compound designed for clear coats and apply it with a microfiber cloth. Work it into scratches using a buffing motion. Remove residues and rinse after polishing.

Cerium Oxide Powder

Make a slurry with water and cerium oxide powder and rub it on the scratched area using a cloth. Allow it to dry then buff it off. This will gradually minimize superficial scratches.

Quartz Countertop Finishing Pads

These are pads made of ultra-fine fibers that can polish out light scratches. Use them dry or with a dollop of quartz polish. Gently rub in a circular motion until scratches diminish.

With consistent application of these methods, you can greatly reduce the look of minor surface scratches on quartz.

Deeper Scratches:

For more prominent scratches that cut into the surface, these options are best:

Fill with Colored Epoxy

Select an epoxy resin that is tinted to closely match your quartz color. Mix the epoxy and apply it carefully over the scratch using a putty knife, ensuring the filler settles into the groove completely. Once dry, sand flush and then polish area.

Fill with Clear Epoxy

For wider scratches, fill with a clear drying epoxy resin designed for countertops. Match the depth of filler with groove depth. Overfill slightly then sand down flat after drying. This transparent filler is less noticeable.

Filler Wax Sticks

These are solid wax filler sticks that come in colors matched to popular quartz hues. Rub the stick over the scratch to pack the wax into the groove fully. Buff off excess wax with a cloth once dry. Quick and easy application.

laminate Repair Kit

Use small cyanoacrylate tubes from a laminate repair kit to flow into scratches. Accurately match color. Sand and polish once cured. Works best for straight short scratches.

Wet Sand with Finishing Pads

Lightly wet sand across the scratch with 400 grit sandpaper to flatten and smooth it out. Follow up with series of quartz finishing pads to restore sheen. Requires precision sanding to avoid damage.

Building up colored fillers and carefully sanding allows you to hide more prominent scratches on quartz surfaces.

Gouges and Chips:

Lastly, here are the techniques to fix the most severe quartz damage:

Professional Refinishing

For deep gashes or chunks of missing quartz, professional countertop refinishing may be required. Licensed technicians have access to fillers, coloring agents, epoxy, and polishing equipment to seamlessly repair significant damage. This is the best but most expensive option.

Quartz Filler and Epoxy

Fill gaps with colored quartz filler which contains ground up quartz material in epoxy binder. Pack it tightly into the hole and allow to cure fully. Once hardened, sand until smooth and flush. Matching the color and finish requires skill.

Color-Matched Caulk

For small chips at the counter edges, use a caulk or sealant that is precisely color matched to the quartz. Fill and tool to create a smooth finish. Once dried, buff with fine sandpaper.

Replacement Quartz Piece

For damage on a counter edge or small section, cut out the damaged part and bond in a replacement quartz piece cut to fit exactly. The new quartz will need to be from the same manufacturer and color. Requires seamless installation.

Extensive gouges, cracks, and missing sections will require rebuilding with specialized quartz fillers, sealants, and replacement parts. Professional help may be needed for large repairs.

Best Practices for Repair Process

To increase your chances of a smooth repair process and minimize the look of any fixings to your quartz countertop, follow these handy tips:

  • Take your time and don’t rush the process. Smooth repairs come with patience.
  • Always start with the least invasive method first before trying more aggressive scratch removal techniques.
  • Test products and methods in inconspicuous areas first to ensure it does not worsen appearance.
  • Carefully follow all instructions for repair products for timing, drying, curing, sanding, etc.
  • If applying epoxy or filler, mask surrounding area with painter’s tape to avoid spillage onto rest of counter.
  • When sanding, always use light pressure and work in the direction of the scratches to avoid deeper damage.
  • Be prepared to do multiple applications of fillers or finishes to get a perfectly smooth blend.
  • If a repair stands out, you may need to refinish the entire countertop surface for a uniform look.


Below are answers to some frequently asked questions about fixing quartz countertop scratches:

Can I use automotive wet sandpapers on my quartz countertop scratches?

Yes, you can wet sand very lightly with 400, 600, 800, and 1000 grit wet sanding automotive papers on deeper scratches. Always finish by restoring sheen and polish with buffing pads.

What are quartz finishing pads?

These are specialty pads made with ultra-fine fibers that can polish out light scratches. Use them dry or with a dollop of quartz polish. Rub in a circular motion. Start with least aggressive pad then move up grits.

Should I rub a walnut on my quartz scratches?

No, this DIY scratch removal method does not work well on quartz. It may end up spreading oil residue and potentially causing haze. Use dedicated quartz repair products instead.

How do I know if my scratch exposes the filler underneath?

Look closely at the scratch in bright light – if you see a difference in color or particles compared to surrounding quartz, it means the filler underneath has been exposed. These deeper scratches need filling.

Can I use automobile touch-up paint in my quartz countertop scratches?

No, automotive touch-up paints are not designed for quartz and may not adhere or withstand use on countertops. Use specialized quartz repair compounds instead.


In summary, fixing scratches on quartz countertops involves first properly evaluating the level of damage, then using the most suitable method from abrasive rubbing, fillers, sanding, and polishing to reduce the appearance of scratches. With some effort and the right materials, you can successfully remove light scuffs or significantly improve the look of deeper cuts and damage. When in doubt, call a professional for extensive quartz repairs. With the techniques outlined, you can restore your quartz countertop to its original flawless condition.
