How to Fix Scratches in Quartz Countertops

Quartz countertops are popular in many homes for their durability, aesthetics, and low maintenance. However, like any surface, they can get scratched over time. The good news is that there are ways to reduce the appearance of scratches and even repair them in quartz countertops. Here is a guide on how to fix scratches in quartz countertops.

What Causes Scratches in Quartz?

Quartz is remarkably scratch-resistant but not entirely scratch-proof. The main causes of scratches include:

  • Dragging heavy, abrasive objects like pots and appliances across the surface
  • Not using a cutting board and slicing food directly on the countertop
  • Harsh scrubbing with abrasive cleaners or scouring pads
  • Accidental drops of sharp kitchen tools like knives

Regular wear and tear will eventually take a toll on the surface. The severity depends on the quality of the quartz material too.

Can You Repair Scratches in Quartz yourself?

Minor superficial scratches can be repaired yourself, but deeper ones will likely require professional help. Here are some DIY methods to reduce scratches:

Cleaning and Polishing

Gently scrubbing with a soft cloth, mild detergent, and warm water can help reduce the visibility of superficial scratches. Use a circular motion. After cleaning, apply a thin coat of quartz countertop polish to add shine and fill scratches. Avoid wax-based polishes.

Sanding and Re-polishing

For deeper scratches, gently rub the area with extra-fine sandpaper (400 grit or higher). Apply pressure evenly and sand in the direction of the scratches. Start coarse and work up to finer grit. Finally, use a polishing compound or paste. This will smooth and restore the finish.

DIY Scratch Repair Kits

You can find specialty scratch repair kits formulated for quartz countertops. They contain materials like acrylic resin to fill scratches and restore the quartz. Follow kit directions carefully. Buff to blend repairs.

Professional Repairs for Deep Scratches

If DIY methods don’t work, especially for long, deep scratches, consider hiring a professional stone restoration company. They have commercial-grade tools, materials, and expertise to resurface and refinish your countertops. Common professional repair techniques include:

  • Grinding – Using rotary tools to gently grind away the scratched layer and expose smooth quartz underneath. This only works if the damage isn’t too deep.
  • Filling – Filling scratches with a clear resin. The material is tinted to match the quartz color. The area is then sanded and re-polished.
  • Full resurfacing – For extensive damage, the countertop may need honing with abrasives or a chemical etch to remove the top damaged layer. This is followed by polishing to restore the smooth finish.

Pro repairs typically cost around $100 to $200 per hour. Get an estimate beforehand.

How to Prevent Scratches in Quartz

Prevention is easier than fixing scratches later. Follow these best practices:

  • Use cutting boards, trivets, pads under appliances. Never cut or slide objects directly on quartz.
  • Avoid harsh cleaners with acidic or abrasive ingredients. Use a mild detergent.
  • Blot up spills quickly to avoid stains which can wear away the surface over time.
  • Apply a quartz sealer every 1-2 years for added protection.
  • Handle heavy pots, pans, and appliances carefully. Don’t let them drop or drag on the quartz.
  • Don’t place hot pans directly from the stove or oven onto the countertop.

With some care and maintenance, quartz countertops can stay looking beautiful for years. But scratches do happen occasionally. Know that there are ways to reduce their appearance or repair them to restore your countertops. Professional help is advisable for deep scratches or extensive damage.

Frequently Asked Questions about Fixing Quartz Countertop Scratches

Can I use bleach to clean scratches on my quartz?

No, avoid using bleach or other harsh chemicals on quartz countertops. The abrasive ingredients can actually worsen scratches and damage the surface further. Use only a mild detergent and soft cloth.

What household items help fill small scratches in quartz?

Petroleum jelly, olive oil, nail polish remover containing acetone, and cyanoacrylate glue can temporarily fill very minor scratches in a pinch, but commercial quartz repair kits or professional repairs are recommended for best results.

How deep of a scratch can be repaired in a quartz countertop?

Light surface scratches less than .3mm deep can be smoothed and buffed out with sanding and polishing methods. Deeper scratches usually require professional repairs. If the scratch catches on your fingernail, it likely needs an expert repair job.

Will DIY scratch repair methods work on engineered quartz?

Yes, DIY kits and methods like sanding and re-polishing can repair superficial scratches in engineered quartz. Follow product instructions carefully based on your specific brand. Avoid wax-based polishes. Get professional help for deep scratches.

How can you tell if your countertop is made of real quartz vs. engineered quartz?

Real natural quartz will show unique natural variations, pits, and fissures indicative of a stone surface. Engineered quartz has a more consistent appearance without natural stone markings. Check with your countertop supplier if uncertain.

Should you seal quartz countertops before or after repairing scratches?

It’s best to apply a sealing product after finishing repairs, not before. The sealant could interfere with the scratch fillers adhering properly. Once repairs are polished and smoothed out, seal the countertop for added protection.


Regular cleaning and being careful about not sliding or placing hot objects directly on the surface can prevent many scratches in quartz countertops. But superficial scratches are common and can often be smoothed out with DIY methods like polishing, sanding, and using repair kits. For deep scratches or extensive damage, professional quartz repair and resurfacing services are recommended to restore your countertops to a pristine, scratch-free condition. With some care and effort, scratches in quartz don’t have to be permanent eyesores.
