Can You Repair Quartz Countertops? The Complete Guide

Quartz countertops are an increasingly popular choice for kitchen and bathroom remodels thanks to their durability, aesthetics, and minimal maintenance requirements. However, like any other countertop material, quartz can become damaged over time. So a common question homeowners have is: can you repair quartz countertops?

The short answer is yes, quartz countertops can be repaired in many cases. However, the specific repair method depends on the type and extent of damage. Minor damage like light scratches and scuffs can often be buffed out. But more severe damage like chips, cracks, and stains may require professional repair or replacement.

In this complete guide, we will cover everything you need to know about repairing quartz countertops, including:

What is Quartz?

Before getting into quartz countertop repairs, let’s quickly review what quartz is and why it has become such a popular countertop choice:

  • Quartz is an engineered stone made from natural quartz crystals combined with resins and pigments.
  • It is harder and more durable than natural stone like granite or marble. Quartz has a hardness rating of 7 on the Mohs scale while granite is around 6 or 7 and marble is a 3.
  • The resin binds the quartz crystals together making quartz less porous than natural stone. This makes it very resistant to stains.
  • Quartz comes in a wide variety of colors and patterns to suit any style. From solid white to mimics of granite and marble to vivid blues and greens.
  • Quartz is resistant to chips, scratches, heat, and stains. However, it is not completely indestructible.
  • With routine care, quartz countertops can last for many years and even decades.

So in summary, quartz combines the aesthetics of natural stone with increased durability and low maintenance needs. But what happens when you do get damage? Let’s look at how to repair quartz counters.

Types of Damage to Quartz Countertops

While quartz is incredibly durable, it can become damaged with improper use over time. Some of the most common types of damage include:

Light Scratches

The quartz surface can get light superficial scratches from things like cutting boards, pans, and appliances being slid across it. Silverware can also leave fine scrape marks. These light surface scratches are generally only visible under certain lighting conditions.

Deeper Scratches and Gouges

Quartz can sustain deeper scratches, gouges, and cuts from things like knives or dropped heavy objects. This type of damage penetrates through the quartz surface leaving clearly visible marks.

Chips and Cracks

Hard impacts from heavy objects being dropped can lead to chips, cracks, and fissures in the quartz. Damage is often concentrated along the edges and corners.

Heat Damage

While quartz is heat resistant, exposure to extreme direct heat can cause cracks, marks, and discoloration. Burn marks are a type of heat damage.


Quartz resists stains very well but is not impervious. Prolonged exposure to strong chemicals and dyes can cause discoloration. Foods like grapes, berries, and tomatoes can also stain over time.

So while quartz is very durable, various types of damage can occur under daily use and improper care. The good news is that many of these damages can be repaired. Let’s look at your options.

Repairing Minor Damage: Scratches, Scuffs, Marks

Minor surface damage like scuffs, scrapes, etched marks, water spots, and light superficial scratches are relatively easy to remove from quartz counters yourself. Here are some DIY methods:

Cleaning and Polishing

For light surface scratches and scuffs, the simplest fix is just a thorough cleaning and polishing. Mix a mild non-abrasive cleaning solution like dish soap, a 5% white vinegar solution, or an ammonia-based cleaner. Use a soft cloth or non-abrasive scrubbing pad to gently clean the entire quartz surface. This will help reduce the visibility of minor scratches.

After cleaning, apply a specialty countertop polish like MK Diamond Products Premium Granite & Quartz Polish. Use a soft cloth and gentle circular motions to work the polish into the surface. Regular polishing helps maintain the quartz’s glossy finish and minimize the appearance of light marks.

Sanding and Buffing

For slightly deeper scratches and scuffs, you may need to sand and buff the spot out. Start by cleaning the quartz thoroughly. Use a countersink tool or orbital sander at the lowest setting with 400 grit sandpaper to gently sand the affected area. Take care not to remain in one spot too long or you can create deeper depressions.

Once sanded smooth, wipe away all dust particles. Apply a quartz-safe polishing compound to a soft cloth and buff the sanded spot in a circular motion. Clean excess compound away and follow up with a quartz polish to restore the surface gloss.

Baking Soda Scrub

For isolated etching marks, water spots, and some light stains, make a paste of baking soda and water. Dip a soft cloth or scrubbing pad in the paste and rub the affected area using gentle pressure. Rinse thoroughly and dry with a soft cloth. Finish by applying a quartz-specific polish.

Test abrasive cleaning methods like sanding and baking soda scrubs in an inconspicuous area first to ensure it does not dull or damage the quartz surface.

With some simple cleaning, sanding, and polishing, you can remove many minor marks on quartz yourself. But what about more severe damage? Let’s look at professional repair options.

Repairing Significant Damage: Chips, Cracks, Deep Scratches

For significant damage like chips, cracks, gouges, and deep scratches, professional repair is usually needed. Qualified technicians have access to specialized tools and materials for quartz repair including:

Color-Matched Filler

For chips, gouges, divots, and cracks wider than a hairline, technicians can fill in the damage with a color-matched quartz filler. The filler is precisely matched to your countertop’s hue and texture. Once cured, it is sanded and buffed to blend in seamlessly.

Epoxy Resin

For hairline cracks and fractures under 1 mm wide, liquid epoxy resin can be injected. Capillary action draws the adhesive deep inside the fissure to bond it from within. Once hardened, the repaired crack is nearly invisible.

Polishing to Blend Scratches

Deep set scratches can often be reduced by grinding down the surrounding surface to the depth of the scratch and then polishing. This makes the scratch far less noticeable although it may not disappear completely.

Panel Replacement

In cases of extensive damage where cracks run across a large section of the countertop, the best option is to remove and replace the damaged quartz panel. A professional can cut out and install a new quartz section seamlessly. This avoids replacing the entire countertop.

So while chips, cracks, and deep damage are more difficult to address, professional quartz repair technicians have the specialized tools and skills to restore your countertop to near original condition in many cases. Be sure to hire an experienced repair company.

DIY Repair Tips and Precautions

While it is possible to perform minor repairs yourself, quartz does require some special care and precautions. Here are some important DIY repair tips:

  • Always test any cleaning or abrasive method on an inconspicuous spot first. Quartz can show gloss differences if you are not careful.
  • Use only quartz-approved cleaners and polishes. Avoid highly acidic or alkaline cleaners which can dull the surface.
  • Sand and buff damaged areas with minimal pressure to avoid creating deeper marks. Work slowly and check often.
  • Match the finish carefully when applying polishing compounds. Too glossy of a finish will stick out.
  • For cracks, chips, or severe damage, call a pro. DIY repairs often fail or cause further damage in these cases.
  • Check for color stability. Exposure to sunlight can cause uneven fading of repairs over time.

With some care and caution, minor quartz repairs can be successfully completed at home. But don’t hesitate to hire a professional if the damage is beyond your skill level.
