How to Fix Chip Quartz Countertop

Chipped or damaged quartz countertops can be an eyesore, but with the right techniques and materials, it is possible to repair them and restore their beauty. Here is a comprehensive guide on how to fix chip quartz countertop surfaces.

Assessing the Damage

The first step is to assess the extent of the damage. Small chips, cracks, and scratches can often be repaired, while larger chunks missing may require a professional fabricator.

Things to look for:

  • Size of the chip – Small chips under 1/4 inch can often be repaired, while larger gaps will be more difficult.
  • Depth – Surface scratches are easiest. Deeper chips exposing the substrate will require more work.
  • Location – Repairs on the countertop edges or high traffic areas may be subject to more wear.
  • Pattern – On patterned quartz, matching the design during repairs takes skill.

Take photos of the damage to refer to later during the repair process. Also note the quartz brand and pattern if applicable.

Cleaning and Prepping the Area

Thoroughly clean the area to remove any dirt, grease, or debris which could affect adhesion. Use a mild non-abrasive cleaner and soft cloth.

Sand the chipped edges lightly with 120-150 grit sandpaper to rough up the surface. This allows the repair compound to bond better. Blow away all dust with compressed air.

Use painter’s tape to mask off the area around the chip. This keeps excess repair material off of the undamaged sections. Apply tape 1-2 inches wider than the actual chip.

Filling Chips and Gaps

For small chips, a colored epoxy resin compound designed for solid surface repairs can be used to fill in the damaged section. These are available on Amazon or hardware stores.

Follow the product instructions closely to mix and apply the epoxy. Fill the chip slightly higher than the surrounding area. The excess material will be sanded flush later. Allow the resin to fully cure overnight.

For larger gaps, use clear epoxy as a filler base. Mix in pigment powder to try and match the surrounding quartz color and pattern. Allow this layer to fully harden.

Next, use the colored quartz repair epoxy to create the finished surface layer. Try to match the thickness of the surrounding quartz. Let cure completely.

Sanding and Polishing

Once repairs have hardened, use 120-220 grit sandpaper to level and blend the filled area flush with the countertop. Sand evenly across repair and surrounding area.

Step down gradually to 400 and then 800 grit sandpaper for a smooth seamless finish. Use a sanding block rather than just the paper.

Finally, polish the sanded area with a rubber polishing pad and quartz polish cream. Buff until the sheen matches the surrounding countertop. Clean away all residue.

For pits and scratches, fill with clear 2-part epoxy resin specifically made for quartz repairs. Sand and polish once cured until smooth and blended.

Preventing Further Damage

To help prevent chips and scratches:

  • Use cutting boards and hot pads rather than cutting directly on the quartz.
  • Don’t drop heavy objects on the surface. Apply sealers to protect.
  • Clean with a soft cloth and mild cleaner, not abrasive pads.
  • Inspect and touch up sealers and polished areas over time.

With care and proper materials, chipped quartz countertops can be repaired to look almost new again. Be sure to assess the type and extent of damage prior to repairs. With some time and patience, even beginners can achieve great results.

Frequently Asked Questions About Repairing Quartz Countertops

What is the easiest DIY method for fixing small chips in a quartz countertop?

For small chips less than 1/4 inch, using a colored quartz repair epoxy that can be sanded and polished is the easiest option. Just thoroughly clean the area, lightly sand, apply tape, fill the chip with epoxy, allow to cure, sand flush, and polish.

Can I use concrete patching compound instead of epoxy?

No, concrete fillers are not recommended. They lack the adhesive strength and flexibility needed for longevity in quartz repairs. Use a specialized quartz epoxy resin.

Should I try to crazy glue a broken chip back into place?

While this may seem like an easy fix, it likely won’t last. The crazy glue bonds won’t be strong enough long-term on the quartz. Remove any loose pieces and fill the gap with repair epoxy rather than trying to glue fragments back together.

How well do quartz repair kits from big box stores work?

Many kits available at home improvement stores are low quality and may not achieve desirable results. Opt for epoxy resins designed specifically for solid surface repairs for best results.

Can I repair quartz myself or do I need to hire a pro?

For small chips, you can likely complete the repairs yourself with the right materials and some DIY experience. But for large damaged areas or complex patterned quartz, hire a professional fabricator for best results.

What homemade options can I use in a pinch to temporarily fill a damaged spot?

While not perfect, in a pinch you can use clear nail polish, super glue, or two part auto body filler putty to temporarily fill small chips until a more permanent epoxy repair can be made.

How long will my DIY quartz chip repair last?

When done properly with the right materials, small quartz repairs can last years. Larger repairs are less stable long-term. Be diligent with sealing and polishing to maximize durability.


Damaged quartz countertops are frustrating, but in many cases the chips, cracks, and scratches can be repaired successfully. Carefully assess the type of damage to determine the best repair approach. With some diligence, specific quartz repair products, and DIY experience, even major chips can be restored to look nearly invisible. Just take care to properly fill, sand, polish, and maintain the area. With a little time and effort, your countertop can look beautiful again.
