Quartz countertops are durable and low-maintenance, but chips and cracks can still occur over time. Fixing a small chip along the edge of a quartz countertop is possible with the right materials and techniques. Here’s a step-by-step guide to repairing quartz countertop edge chips yourself and restoring your countertop’s smooth appearance.
Assessing the Quartz Countertop Chip
Before attempting to fix a quartz countertop chip, first assess the damage. Pay attention to:
- Size – Is it a small chip or a large chunk missing from the edge? Small chips under 1 inch can often be repaired, but larger missing pieces may require professional help.
- Depth – How deep does the chip penetrate the quartz surface? Surface-level chips are the easiest to fix.
- Location – Make note of where on the countertop edge the chip is located. This will determine the repair approach.
- Color – What color is the quartz? Having a color-matched filler will provide the most seamless fix.
Once you’ve evaluated the specifics of the chip, you can determine if it’s within your DIY abilities or if you need a pro.
Gathering Supplies for Repairing a Quartz Countertop Edge
Repairing a chip in a quartz countertop edge requires just a few specialty supplies:
- Clear epoxy adhesive or resin filler specifically designed for quartz countertops
- Colored filler compound to match your quartz color
- Mixing sticks/stirrers
- Tape (painters tape or masking tape)
- Sandpaper (120 to 220 grit)
- Soft rags
- Acetone or denatured alcohol
- Putty knife or scraper
- Razor blade
Choose an adhesive filler designed for quartz rather than a generic epoxy. The filler should be formulated to bond securely to quartz.
Prepping the Quartz Countertop Chip for Repair
Before filling a chip, prep the area to ensure proper adhesion:
Clean the Area
Wipe away any dirt, grease or debris from the chip and surrounding countertop area using acetone/alcohol and rags.
Sand the Surface
Use 120-220 grit sandpaper to rough up the surface inside the chip and about 1 inch around it. This helps the filler adhere.
Tape Off the Area
Apply strips of painters tape around the chip to prevent filler from spreading where it’s not wanted. Leave the chip exposed.
Dry & Clean Again
Use a clean, dry rag to remove any residue before repairing the quartz countertop edge.
Filling and Repairing the Quartz Countertop Edge Chip
Once prepped, you can fill the damaged area:
Mix the Filler
Prepare the epoxy filler according to package directions. Mix small batches to prevent hardening before use. Add colorant to match your quartz.
Fill the Void
Use a putty knife, scraper or popsicle stick to fill the chip fully with the colored epoxy filler. Overfill slightly.
Smooth the Surface
Before drying, smooth the filler flush with the surrounding quartz using a scraper or putty knife. Remove any excess.
Allow to Cure
Follow cure times on filler instructions. Most take 24-48 hours to fully harden before sanding/polishing.
Sand & Polish
Once cured, use 120-220 grit sandpaper followed by finishing pads to blend and polish the repair smooth.
Remove Tape
Carefully remove the tape to reveal crisp repair edges. Re-polish if needed.
Achieving an Invisible Quartz Countertop Chip Repair
With care and the right filler products, you can achieve professional-looking results when repairing a quartz countertop edge at home. Here are some tips:
- Take your time prepping the surface – this is key to good adhesion.
- Tape off the area thoroughly to prevent messes and visibility of repair edges.
- Use high-quality, quartz-specific filler made for durability and color-matching ability.
- Overfill the chip slightly, then sand and polish to a perfectly smooth finish.
- Make sure to match the filler color as closely as possible to your quartz.
- Cure filler thoroughly before sanding or polishing to prevent pulling out of the repair.
- Blend edges of the repair into the surrounding quartz using fine grit sandpaper.
- Finish by polishing with buffing pads to restore sheen and hide any remaining visible edges.
With some patience and the right process, you can make chips in quartz countertop edges virtually disappear.
FAQs About Repairing Quartz Countertop Edge Chips
Can I repair a quartz countertop chip myself?
Yes, small chips and surface damage along the edges of a quartz countertop can often be repaired successfully with DIY methods, provided you use the right filler products and techniques.
What is the best filler to use?

Fixing a chip along the edge of a quartz countertop is definitely possible as a DIY project. Assessing the specifics of the damage and gathering the right supplies is the first step. Properly cleaning, sanding and taping off the area ensures good adhesion when you fill the chip with color-matched epoxy. With curing time, sanding, polishing and blending the repair area, you can make a chipped quartz countertop edge look smooth, seamless and like new again. Take your time with the project, use quality filler products, and you can avoid replacing the entire countertop.
