5 Easy Ways to Repair a Chip in Quartz Countertop

Quartz countertops are some of the most sought-after countertop surfaces on the market because they're more durable, stain-resistant, and heat-resistant than many of their counterparts. However, that doesn't mean they can't be damaged! Learn how to repair chips in quartz countertops with these five easy methods.

1) Identify the Type of Repair Needed

The first step is determining what kind of repair you will need. This can be done by probing at the area of the chip with your fingernail and finding which tool works best. The most common tool used is sandpaper because it removes just enough material without damaging the surrounding countertops. However, if you are comfortable using these tools on an orbital sander or bench grinder, then either one could work as well. When using sandpaper, choose 180 or 220 grit for quicker results and fewer chances for damage to the quartz surface.

2) Consider Your Budget

For the novice DIYer, the best way is to purchase your own equipment, but if that's not feasible, companies can be hired for repair purposes. If you don't have a lot of money and are serious about doing it yourself (but you're not an expert), plan on making multiple trips and spending anywhere from four hours each trip up to eight or more. You'll want to hire professionals to repair any cracks that penetrate below the surface of the quartz. Any professional company will charge an hourly rate plus additional expenses for materials such as adhesive supplies, grout sealer, and primer for new color stains. For example, replacing filler material and resealing surfaces could cost up to $500 without additional labor costs associated with sealing cracks or adding new material beneath damaged areas. 

3) Gather Your Materials

Begin by gathering the materials needed to complete the project: tape measure, pliers, screwdriver, silicone sealant, and quartz countertop chips.

4) Prepare the Area For Repair

Check your chipped area and make sure you have no other damage. Clean the damaged area with mineral spirits or paint thinner and dry with a towel. Remove any dried particles using an emery board and place masking tape on the non-damaged surface of the quartz counter. Then take the drill bit that is slightly smaller than the depth of the chip. Drill all around the top edge of your crack, being careful not to let the bit breakthrough. Make sure you are not drilling too deep since it is easy for bits to snap off in quartz. Sand down your repaired area by gently rubbing an emery board back and forth over it--keep going until all of your chips are completely smoothed out or until there are just microscopic nicks left over.

5) Remove and Replace Chipped Pieces (Optional)

If there is an unfinished side of the stone, then it may be necessary to remove the entire piece. Using some type of adhesive, glue the new slab onto the counter and seal it with a mixture of mineral spirits and acrylic paint. Let dry for at least two hours before using so that you can ensure that the new quartz counter is well adhered to the underlying surface. If there is already a finished side, then all you need to do is grab your filling material and fill in the chip. Use a damp rag or sponge dipped into mineral spirits to remove any excess filler and allow it to dry completely before touching it with anything or using it as an area on your kitchen's prep surface again!


Overall, you can try several different things to fix a chip in your quartz countertop. The best solution really depends on the severity and location of the chip. You can also consider what materials you have on hand as well as which solution will be the quickest for you.
