Can You Fix a Chipped Quartz Countertop?

Assessing the Damage

The first step is to assess the extent of the damage. Small chips, minor scratches, and hairline cracks can usually be repaired. However, deep scratches, large chunks missing from the countertop, or cracks across the entire surface are more problematic. Severe damage may require a professional fabricator to cut out and replace the damaged section.

Carefully examine the chipped area. Use a ruler or tape measure to determine the length and depth of any cracks or scratches. Also, check the thickness of the countertop in the damaged area. Quartz countertops are made by layering crushed stone and resin. Deep damage that penetrates through the top layer may expose the lighter-colored underside.

Cleaning and Prepping the Surface

Before attempting any repairs, thoroughly clean the area with a mild nonabrasive soap and water. This removes any dirt, grime, or debris that may have collected in the damaged spot.

Once clean and dry, sand the chipped area lightly with fine grit sandpaper. This helps remove any rough or uneven edges and prepares the surface for the repair compound. Take care not to enlarge the existing chip or scratch.

Filling Chips and Scratches

For minor chips, scratches, and hairline cracks, a chip repair kit is an easy option. These kits contain colored putty, hardener, and sometimes primer specially formulated for quartz. The putty color can be matched to your existing countertop. Follow the manufacturer’s directions carefully.

Apply a thin coat of primer if needed, then thoroughly mix the putty and hardener. Fill the damaged spot just above the surface level. Allow the mixture to cure fully (usually 24-48 hours). Once hardened, sand flush with the surrounding countertop. Finish by polishing with a stone polish to restore the smooth factory finish.

Disguising Damage

For slightly larger chips or surface flaws, you may be able to disguise the imperfections using filler materials:

  • Colored epoxy – Mix two-part clear epoxy resin with a pigment powder to match your quartz color. Fill the chip and allow to fully harden before sanding smooth.
  • Clear epoxy with crushed quartz – For a more seamless repair, stir fine crushed quartz into clear epoxy resin. Match the particle size and color. Coat the damaged spot just above surface level.
  • Polymer concrete patch – Concrete patch designed for stone surfaces can fill chips and adheres well. Mix to match the quartz color.

Take care to smooth and level these materials completely flush. Uneven repairs will be more noticeable.

When to Call a Professional

For deep gouges, large broken sections, and cracks over 3 inches, consider calling in a professional quartz fabricator. They have access to specialized tools, materials, and training for seamless repairs. Damaged corners or overhangs often require professional help as well.

Replacing a section of the countertop may be needed for extensive damage that compromises the structural integrity or appearance. A professional can cut out and install a new quartz piece to match the existing seamlessly. Although expensive, partial replacement is often cheaper than replacing the entire countertop.

Preventing Damage

To help avoid chips and scratches:

  • Use cutting boards and hot pads. Never cut or place hot items directly on the quartz.
  • Clean spills promptly to avoid stains setting.
  • Avoid abrasive cleaners that can dull the finish.
  • Handle heavy objects carefully around the countertops.
  • Install a sink-rail to protect sink edges from impact.

With proper care and prompt repairs, minor chips and scratches don’t have to ruin the beauty of your quartz countertops. Pay attention to surface flaws when they first occur for the easiest fix. But even more noticeable damage can often be repaired by a skilled homeowner or professional.

Frequently Asked Questions About Fixing Chipped Quartz Countertops

Can I repair a chipped quartz countertop myself?

Yes, minor chips, scratches, and hairline cracks can often be repaired by a DIY homeowner using a chip repair kit, epoxy, or concrete polymer patch. Match the color carefully for the least noticeable fix.

How do you fix a crack in a quartz countertop?

For small hairline cracks, use a colored epoxy or concrete patch. Larger cracks may need professional repair or replacement of the damaged section. Cracks over 3 inches usually require pro help.

Should I replace or repair a chipped quartz countertop?

Minor chips and scratches can be repaired inexpensively. But deep gouges, large broken chunks, and extensive cracking often require replacing the damaged section or countertop. Evaluate cost vs. appearance.

Does quartz stain easily?

Quartz is non-porous, so it resists stains well. But spills should be cleaned up promptly. Some materials like wine, oil, and dyes can stain if left too long. Annual resealing helps prevent stains.

Can you buff out scratches in quartz?

Light scratches can be sanded and polished out using fine grit sandpaper and a quartz polish compound. This restores the smooth surface. Deeper scratches likely require filling with a repair compound or replacement.

How much does it cost to repair quartz countertops?

DIY chip and scratch repairs cost $10-$50 for materials. Professional repair of a small damaged section averages $150-$300. Full replacement of a section, or the entire countertop, can cost $2,000-$5,000.


Chips and cracks in quartz countertops happen, but don’t rush to replace the entire surface. Carefully assess the damage and options for repair. With the right materials and techniques, most minor flaws can be fixed affordably by a homeowner. But extensive damage may benefit from calling in a professional quartz fabricator for the best results. Paying attention and making prompt repairs can keep your quartz countertops looking like new for years.
