How to Repair Chipped Quartz Countertop Edge

Repairing a chipped quartz countertop edge can seem daunting, but with the right materials and techniques, it can be an easy DIY project. Here is a step-by-step guide on how to repair a chipped quartz countertop edge.

Assess the Damage

The first step is to assess the extent of the damage. Look closely at the chipped area and determine how deep and wide the chip is. This will help you figure out the best repair method.

  • Small chips less than 1/4 inch deep can often be repaired with touch-up kits.
  • Larger chips may require more extensive patching and resurfacing.

Take measurements of the chipped area so you know how much material will be needed for the repair.

Gather the Necessary Materials

Depending on the severity of the chip, you may need some or all of these materials:

  • Quartz countertop touch-up kit – Contains colored putty, sponge & instructions for minor repairs
  • Automotive epoxy adhesive – A two-part epoxy ideal for bonding quartz
  • Tinting pigment – Used to color-match the repair compound
  • Mixing sticks/containers – For mixing epoxy resin & hardener
  • Sandpaper – Assorted grits to sand down repair areas
  • Polishing compound – Helps restore sheen on sanded areas
  • Shop towels – For wiping away debris & spills
  • Painter’s tape – For masking off repair zone
  • Safety gear – Gloves, goggles, mask if sanding

Purchase a touch-up kit or epoxy in a color that matches your countertop. The manufacturer can provide the exact color specifications if needed.

Clean and Prepare the Area

Thoroughly clean the damaged area with soap and water to remove any dirt or debris. This will allow the repair compound to properly adhere.

Use painter’s tape to mask off the area around the chip. This protects the surrounding surface from damage during sanding and resurfacing.

If the edges are ragged or uneven, use a file or extra-fine sandpaper to smooth them out. The repair will blend better if the chipped edges are straight.

Apply Repair Compound

For minor chips: Follow the directions for the touch-up kit. These typically involve dabbing the putty into the chip with a applicator, allowing it to dry, then sanding smooth. Apply touch-up putty in thin layers, building up the area until it’s slightly higher than the surrounding quartz.

For larger chips: Mix a small batch of tinted epoxy adhesive according to the manufacturer’s instructions. Spread the epoxy evenly into the chip using a plastic applicator or popsicle stick. Overfill the damaged spot slightly to allow for sanding. Allow the epoxy to cure fully before sanding.

Blend and Refinish the Repair

Once the adhesive has fully cured, start blending and refinishing the repair.

Use 120-150 grit sandpaper to level and smooth the patched area. Sand in a circular motion. There may be some low spots you’ll need to fill in with additional putty.

Switch to 220 grit sandpaper once the surface is flat and feather out the edges so they blend seamlessly.

Remove all dust with a damp microfiber cloth. Apply polishing compound with a soft pad and buff the area to restore the high shine.

Carefully remove the painter’s tape and clean the surface thoroughly. Check the repair to ensure it matches the surrounding area. Add additional tinted epoxy if needed to blend the color.

Protect the Repaired Area

To keep your quartz countertop looking great, take steps to protect the repaired section:

  • Use a cutting board or trivet for hot pots and pans.
  • Clean spills quickly to prevent staining.
  • Avoid abrasive cleaners or scouring pads.
  • Reapply polish every few months to maintain the shine.

Take care around the once-damaged area and your countertops will continue looking beautiful. With the right tools and techniques, you can successfully repair chips and prevent further damage.

Frequently Asked Questions

What is the easiest way to repair a small chip in a quartz countertop?

For small chips less than 1/4 inch deep, using a quartz countertop touch-up kit is the easiest repair method. The colored putty fills in minor chips seamlessly.

Can I use regular epoxy instead of specialty countertop adhesive?

It’s best to use a professional-grade, tinted epoxy designed for countertops. The adhesive needs to be strong, resilient and stain-resistant. Regular epoxy may not hold up over time.

What grit sandpaper should be used for smoothing the repair?

Use 120-150 grit to flatten the area initially, then switch to 220 grit to blend the edges of your repair into the surrounding quartz. Always sand in a circular motion.

How soon can I put items back on the countertop after a repair?

It’s best to avoid setting anything heavy on the repaired section for at least 24 hours. This gives the epoxy time to fully cure so it develops maximum strength and durability.

Will the repaired area of my countertop stain differently?

There may be slight variance in stain resistance where the new epoxy meets the original quartz surface. Take care to wipe up spills quickly and avoid harsh cleaners. Reapplying polish helps even out the appearance.


Repairing a chipped quartz countertop edge is definitely doable as a DIY project. Assess the damage, gather the right supplies, thoroughly prep the area, then use touch-up kits or tinted epoxy to fill chips and divots. Proper sanding and polishing will blend the repair seamlessly. Just remember to take steps to protect the surface going forward. With some patience and the right techniques, you can make damaged countertops look good as new again.
