How to Repair Quartz Countertop Finish

Having quartz countertops can add beauty and value to your home. However, like any surface, quartz can become damaged over time. Thankfully, there are ways to repair quartz countertop finishes and restore their original appearance. Here is a comprehensive guide on how to repair quartz countertop finishes.

Assessing the Damage

Before attempting to repair your quartz countertops, you’ll need to assess the extent of the damage. Here are some common issues that can occur:

  • Scratches – These appear as thin lines across the surface and can range from superficial to deep gouges.
  • Etch marks – Dull, whitish marks caused by acidic substances like lemon juice or vinegar.
  • Chips/cracks – Small fragments that have chipped off or cracks from impact.
  • Stains – Discoloration from spills that have set into the surface.

Carefully inspect the damage. Shallow scratches may be easier to remove than deep cracks or gouges. For etching or staining, identify the cause to avoid further damage.

Cleaning and Prepping the Surface

Before starting repairs, clean the countertop surface thoroughly with a mild nonabrasive soap and water. Use a soft cloth or sponge rather than an abrasive pad. This will remove debris or residues that could get caught in cracks or scratches.

Rinse several times with clean water and let the surface dry completely. This helps the repair treatment adhere properly.

Repairing Minor Scratches and Etch Marks

For light surface scratches or etching, you can often polish them out by refinishing the top layer of the quartz:

  • Use a smooth polishing pad designed for stone surfaces. Apply a mild polishing cream or solution and rub it into the scratch using firm, circular motions.
  • Work over the scratch until it noticeably improves. Take care not to scrub too aggressively on the undamaged areas.
  • Rinse off the polishing compound thoroughly and dry the surface afterwards. Repeat as needed until the scratch is significantly reduced or removed.
  • For etching, apply a poultice designed specifically to remove etching from stone. Spread a thin layer over the mark, let sit for 15-30 minutes, then rinse clean.

Repairing Chips and Cracks

Small chips or cracks can often be filled in using a colored epoxy resin specifically made for quartz repairs:

  • Clean out any loose fragments or debris from the damaged spot using tweezers or a toothpick.
  • Mix the epoxy resin according to package directions. Apply using a plastic putty knife, pressing firmly into the crack or chip.
  • Allow the resin to cure fully (usually 24-48 hours). Sand smooth any excess resin around the repair if needed.

For best color-matching results, use an epoxy that is tinted to match your quartz surface color. Some kits even include multiple resin colors to blend to your countertop’s custom shade.

Removing Stains on Quartz Surfaces

Here are some tips for removing common stains:

  • Oils, grease: Use baking soda and water to make a spreadable paste. Apply to the stain and let sit for 20-30 minutes before rinsing.
  • Rust: Use a rust-removing product designed for quartz. Apply and let sit for 5 minutes before rinsing. Wear gloves.
  • Dried spills: Gently scrape off any hardened material with a plastic putty knife, taking care not to scratch the surface.
  • Dark stains: Use a non-abrasive cleaner designed for quartz and scrub with a soft cloth or sponge. You may need to do several applications.

Always spot-test stain removers on a small, inconspicuous area first to ensure it does not damage the quartz.

When to Call a Professional

For deep scratches, chips, or cracks wider than a few millimeters, it is best to have a professional fabricator or installer repair the quartz. They have the proper tools, materials, and techniques to fix significant damage.

Seeking professional help is also a good idea if:

  • The damage spans a large area of the countertop.
  • Repair attempts have not successfully improved or removed the flaws.
  • The color-matching for repairs is proving difficult.
  • You do not feel comfortable doing repairs yourself.

Be sure to hire an experienced quartz fabricator, as an improper repair job can worsen damage. Get a few estimates first to compare costs.

Preventing Future Damage

To keep your quartz countertops looking pristine:

  • Use cutting boards and hot pads to protect surfaces.
  • Clean up spills quickly to avoid staining.
  • Avoid using abrasive scrub pads or cleansers.
  • Re-seal quartz every 1-2 years with a penetrating sealer.

With proper care and timely repairs, quartz countertops can stay looking like new for many years before needing replacement. Following these repair techniques can restore their appearance quickly if damage does occur. Just take care when making repairs to avoid causing further injury to your quartz surface.

Frequently Asked Questions About Repairing Quartz Countertops

Can I repair quartz countertops myself?

Yes, minor damage like light scratches, etching, and small chips can often be repaired yourself using polishing pads and colored epoxy resin kits. But significant damage is best left to quartz fabrication professionals.

How do you fix etching on quartz?

Use a smoothening polish or an etching remover made for quartz. Apply a thin layer to the etched area, let sit briefly, then rinse clean. Repeat as needed until the dull mark disappears.

What is the best glue to repair quartz countertops?

An epoxy resin adhesive specifically formulated for quartz repairs will provide the strongest, most color accurate bond. Be sure to get one tinted to match your surface.

Can you use super glue on quartz countertops?

No, regular super glue is not strong enough for quartz repairs and may discolor the surface. Use a specialized quartz epoxy resin.

How do you remove dried epoxy from quartz?

Gently scrape off any excess dried resin with a plastic putty knife. Then use a solvent like acetone on a cloth to rub any remaining residue off the quartz. Avoid using too much pressure when scraping to avoid scratching the surface.


Repairing damage on quartz countertops is doable with the right materials and techniques. For minor flaws, refinishing or using epoxy fillers can often restore the look of your counters. But deep damage will require a professional fabricator. With some care and effort, it is possible to keep your quartz countertops looking fresh and flawless for many more years before needing to replace them entirely.
