Can You Repair Chip on Edge of Quartz Countertops?

Quartz countertops are popular options for kitchen and bathroom remodels due to their durability, stain resistance, and stylish appearance. However, like any other material, quartz can become damaged over time. Chips along the edges of a quartz countertop are common if the material is accidentally impacted. Fortunately, it is possible to repair chips on quartz countertop edges without having to replace the entire slab. Here is what you need to know about repairing chips on the edges of quartz countertops.

Assessing the Damage

The first step is to assess the severity of the chip. Small chips less than 1/4 inch wide can often be addressed with a simple repair. Larger or deeper chips may require more extensive work. Carefully examine the damaged area and try to determine how deep the chip penetrates into the slab. Quartz is composed of ground natural stone and resins that are molded into slabs under intense pressure and heat. A chip that extends through the top resin layer into the stone interior is more problematic.

Cleaning the Area

Before attempting any repairs, clean the area around the chip thoroughly with isopropyl alcohol to remove any dust, grease or debris. Allow the surface to fully dry. This will allow any repair materials to properly adhere. Use a vacuum attachment and soft brush to remove any loose particles from the damaged spot.

Minor Edge Chips

For small, superficial chips that do not extend deep into the quartz:

  • Use a quartz color repair kit. These kits contain colored resins or putties that can be blended to match the hue of your countertop. Fill in the divot and allow to dry completely. Finish by gently sanding flush.
  • Apply clear nail polish. Use a polish that matches closely to the quartz color. Fill the chip and let dry. The polish will harden to fill in the missing material.
  • Use super glue. Carefully apply a small dot of super glue in the bottom of the chip. Allow to fully cure. Go slowly and avoid getting glue on the surrounding countertop.
  • Apply a wax stick. Lightly heat a crayon wax stick to match the quartz and fill in the damaged spot. Scrape any excess away with a plastic card once dry.
  • Use baking soda and super glue. Make a paste by mixing baking soda and super glue. Fill the hole with the paste, allow to dry, then sand smooth.

These solutions work well for small edge chips less than 1/4 inch across and prevent further cracking or damage.

Larger Edge Chips

For more substantial damage or broken corners, a filler material will need to be secured in place:

  • Two-part epoxy resin. Mix the two compounds according to package directions to create an adhesive resin. Fill the damaged section, allow to fully cure, then sand smooth.
  • Pre-cast quartz filler. Some companies sell small pre-made quartz patches and filler pieces that can be adhered into larger defects and cracks.
  • Acrylic bonding agent and aggregate. Use liquid acrylic to “weld” crushed quartz or stone pieces into the cavity. Take precautions against inhaling quartz dust when handling.
  • Clear two-part casting resin. Fill large chips with a clear casting resin designed for stone. Allow to cure completely then gently sand and polish.

Be sure surfaces are clean before applying any filler product. Follow all safety precautions when handling strong adhesives. Wear eye protection and gloves. The repair may be visible on close inspection but can provide a cost-effective fix.

When to Call a Professional

In some cases, it’s best to have extensive quartz countertop edge damage professionally repaired:

  • Chips larger than several inches across.
  • Cracks extending across the slab.
  • Damage around sinks, faucets or seams.
  • Multiple fractures along the same edge.
  • Broken corners or edges.
  • Chips exposing large sections of interior stone aggregate.
  • Damage caused by extreme heat that may have compromised the structural integrity.

Hiring an experienced fabricator is advisable for major damage that requires cutting, polishing, and securing new quartz material into place. They have specialized tools, materials, and expertise to seamlessly patch significant defects.

Preventing Damage

Taking steps to prevent chips and cracks will save you the hassle of repairs:

  • Use cutting boards, hot pads and trivets to protect the surface.
  • Don’t place excessively hot pans, dishes or appliances directly on quartz.
  • Clean spills promptly to avoid stains and cracks from chemicals.
  • Apply sealants around sinks, faucets and backsplashes to prevent moisture ingress.
  • Avoid sitting, standing or placing heavy loads on countertops.
  • Have sufficient support underneath to prevent sagging, especially with thinner slabs.

With proper care, quartz countertops can remain resilient for many years. But minor accidents do occur in busy kitchens. Knowing your options for edge chip repairs allows you to promptly fix any cosmetic defects and retain your countertop’s beauty.

Frequently Asked Questions About Repairing Quartz Countertop Edge Chips

Can I repair a chip on my quartz countertop edge myself?

Yes, small chips and damage on quartz edges can often be repaired successfully with homemade solutions using materials like super glue, epoxy resin, nail polish, wax sticks and color repair compounds. For best results, thoroughly clean the area first.

What is the easiest DIY method for repairing a chip?

Using a quartz color repair kit is the easiest option for minor damage. These contain premixed putties or resins that blend to match your countertop. Just fill the chip, allow to dry, then sand smooth. Clear nail polish or super glue also offer quick fixes.

Should I try to repair a large chip or call a professional?

For minor chips less than 1/4 inch, DIY solutions often work well. But for extensive damage, cracked corners or pieces breaking off edges, it’s best to hire a skilled fabricator to cut, secure and polish new quartz material into place.

How well do DIY chip repairs on quartz hold up over time?

For small superficial chips, homemade repairs can last for years with proper prep and application. Ensure the repair material bonds securely. But understand that the fix may be more visible on close inspection. Severe damage is best corrected by a professional.

Can chips lead to greater damage or cracking of my quartz countertop?

It’s possible for cracks to spread from an existing chip if the slab is not properly supported underneath or subjected to significant impact. Repair chips promptly to prevent this. Use sealants around sinks, backsplashes and seams.

How can I prevent chips and cracks in my quartz countertops?

Avoid direct high heat, harsh chemicals, standing on surfaces, and heavy impacts that can damage quartz. Always use trivets, cutting boards and heat pads. Clean spills quickly and seal around moisture-prone areas. Support slabs adequately underneath.


Minor chips and dings along the edges of quartz countertops are common over years of use. But these cosmetic defects can often be repaired successfully without having to replace the entire slab. For small superficial chips under 1/4 inch, fillers like epoxy resin, wax sticks, nail polish, baking soda mixes and color repair putties provide effective and affordable solutions. However, more extensive damage requires cutting out and replacing sections of the quartz professionally. With proper care and prompt repairs when needed, quartz countertops can remain beautiful and functional for many years before needing replacement. Learning proper repair techniques allows homeowners to fix chips themselves and avoid costly slab replacement.
