How to Fix Chipped White Quartz Countertops

White quartz countertops can be a beautiful addition to any kitchen or bathroom. However, like any other countertop material, quartz can become damaged over time, especially around the edges. Chips and cracks in a quartz countertop not only look unsightly, but can allow moisture and bacteria to penetrate the surface, leading to more extensive damage. Fortunately, there are several effective ways to repair chipped white quartz countertops and restore their flawless appearance.

Assessing the Damage

Before attempting to fix a chipped quartz countertop, take time to thoroughly assess the damage. Carefully examine the size, depth and location of any chips or cracks. Smaller chips toward the edge of a countertop are usually easier to repair than large chunks missing from high traffic areas.

Determine if the damage is purely cosmetic or if moisture has penetrated beneath the surface. Tap around the damaged area and listen for a hollow sound, which indicates a more serious underlying issue. A moisture meter can help detect if water has infiltrated the quartz.

Understanding the full extent of the damage will determine the best repair method. Cosmetic issues can often be fixed with simple DIY techniques, while moisture damage or large missing pieces may require professional help.

Cleaning and Prepping the Surface

Before attempting to fill chips or gaps, thoroughly clean the area with denatured alcohol to remove any dirt, debris and oils. Carefully sand any rough edges around the chipped area using 300 grit sandpaper. This will help the repair adhere properly.

Wipe away all dust with a clean, dry cloth. Mask off the surrounding area with painter’s tape to prevent accidentally marring the undamaged sections. The quartz must be completely clean and dry for best results.

Using Two-Part Epoxy Filler

For minor chips, cracks and edge damage, a two-part epoxy filler designed for stone repair provides an easy fix. These products contain an epoxy resin and hardening agent that must be mixed together prior to use. Follow all label directions carefully.

Select an epoxy in a close color match to your white quartz. Apply a thin layer using a putty knife, completely filling all damaged areas. Remove any excess filler immediately with a plastic scraper before it dries. Allow the epoxy to cure fully, usually about 24 hours. Once hardened, sand very lightly with 400 grit sandpaper to smooth.

Epoxy fillers bond tenaciously to quartz while providing a hard, durable patch that resists moisture. However, the repaired area may not match the exact color and finish of the surrounding countertop.

Spot Repair Kit

For nearly invisible repairs, many quartz manufacturers sell spot repair kits designed for their products. These kits contain an adhesive patch, color matched filler putty and sometimes primer. Kits made specifically for your brand and color of quartz produce the best results.

First, adhere the patch over the damaged spot per the product instructions. Mix the putty filler and apply it carefully over the patch, using the included scraper to remove any excess. Once dry, lightly sand until the patch blends seamlessly into the surrounding quartz. Matching the color and finish using the kit produces repairs that are barely detectable.

Professional Repairs

For more extensive damage or precise color matching, consider hiring a professional quartz restoration company. Experienced technicians have specialized tools, materials and skills to flawlessly repair chipped edges, gouges and cracks.

Many companies offer color-matching services to perfectly blend the repair into your existing white quartz. This involves mixing custom fillers and epoxies to match the countertop details like veining and shading. Though pricier than DIY repairs, proper professional restoration leaves quartz looking new again.

Preventing Future Damage

To help avoid additional chipping or cracks, have any severely damaged areas reinforced by a countertop company. They can apply an adhesive-backed veneer or autresin banding to strengthen vulnerable edges and high-stress areas.

Take steps to protect the surface from future harm. Use cutting boards rather than cutting directly on quartz. Immediately wipe up spills, especially oils, wines and other acidic foods. Apply wax every few months to increase water resistance. Adding silicone caulk along the edges and joints every year or two prevents moisture penetration.

Have your white quartz professionally cleaned and resealed annually to maintain its flawless factory finish. Be very gentle with fragile overhangs when cleaning to avoid inadvertent chips and cracks. With proper care, your quartz countertops will stay smooth and damage-free for many years.

Frequently Asked Questions About Repairing Chipped White Quartz Countertops

How long does epoxy filler last on a quartz countertop repair?

When properly applied, epoxy filler can last for many years on quartz repairs. Be sure to completely clean and dry the surface first and follow all manufacturer’s instructions for curing times. Regular sealing will also help the epoxy bond last longer.

Can I use white enamel appliance paint to repair chips?

Enamel paint is not a good choice for repairing quartz damages. It does not bond well, will scratch off easily, and does not withstand moisture. Use a specialized quartz epoxy putty or patch kit for more durable repairs.

Is it OK to use superglue to fix a small quartz chip?

Cyanoacrylate “super” glues are not ideal for repairing quartz. They dry too quickly to penetrate into the damage and do not flex well with normal countertop movement over time. An epoxy designed for stone repair will provide a much stronger, long-lasting bond.

Can I repair a chipped quartz edge by myself or do I need a pro?

Minor chips and surface damage on the edges or in corners can often be repaired successfully with DIY methods like epoxy putties. But extensive damage or whole chunks missing will require professional help for proper structural repair and seamless appearance.

How well do white quartz repair kits match the original color?

Repair kits made by quartz manufacturers contain fillers designed to blend perfectly with that specific brand and color. Generic kits won’t match as accurately. Carefully follow all mixing and application directions for seamless spot repairs.


Chips and cracks in white quartz countertops not only detract from their beauty but can lead to further damage if not repaired. With the right materials and techniques, many defects can be fixed successfully through DIY methods. For flawless repairs or extensive damages, seek professional assistance. By properly restoring any imperfections, you can keep your white quartz surfaces in like-new condition.
