In spite of being tough, quartz countertops can get chipped or cracked due to age and accidents. However, in most cases, you can repair the affected area without having to replace the entire slab—if the chip is small, it can just be filled with superglue, epoxy, or caulk. Read for the best ways to fix any chip or crack your countertop, plus how to prevent chips from happening in the future.

Things You Should Know

  • Clean your countertop, put painter’s tape around the damaged area, and fill in the chip with superglue or colored epoxy . Smooth it out with sandpaper after 24 hours.
  • If you have a large crack in your countertop, wash the surface, surround the crack with tape, and fill it in with caulk .
  • For a faster process, fill the crack with acrylic from a quartz repair kit , place the curing strip over it, and shine an LED on the area until it’s fully dry (5-10 minutes).

Repairing Minor Chips with Superglue, Adhesive Filler, or Epoxy

  1. Get rid of any dust and debris around the chip before you start repairing it. Clean the countertop with a soft cloth dipped in warm, soapy water. Never use bleach or ammonia on quartz, as they can dull the surface. [1]
    • Wait for it to completely dry before beginning the repairs.
  2. Stick strips of masking tape around the chipped area to make it easier to apply the adhesive and prevent stains. [2] Get the tape close to the chip, but don’t overlap it.

  3. Adhesive filler or superglue are great materials for repairing minor chips on light surfaces. Apply thin coats of glue over the chip with a brush or spatula until the area is level with the surface again. Let the glue sit for at least 24 hours. [3]
    • Don’t glob on the glue—that’ll make the curing process take much longer.
    • Use superglue for chipped surfaces and thicker adhesive filler for chipped edges.
    • If you still have the chipped piece, just use the superglue to glue it back on. [4]
  4. If you have a dark countertop, opt for a pigmented epoxy instead of superglue. Mix the epoxy according to the instructions on the package (usually, it's a 1:1 ratio) and add your dye. Apply thin coats with a spatula until the chip is entirely full, then scrape off the excess. Let it dry for 24 hours. [5]
    • The epoxy mix may shrink a bit while drying, so it's better to over-fill the chip and sand down the excess later than to underfill it.
    • Once again, use the epoxy to reattach the chipped-off piece if you have it.
  5. Once the chip is entirely full, clean up the excess epoxy by gliding the blade over the surface. Use superfine sandpaper with a 360 to 600 grit to smooth over the patch once it hardens, which usually takes about 24 hours. [6]

Patching Surface Cracks with Caulk

  1. Use a damp cloth and dish soap to clean the area before you get started. Dry it thoroughly before beginning the repair.
  2. Working with caulk can get messy, so stick strips of masking tape around the crack to avoid it from getting on the rest of the countertop. It also helps you get an even line while caulking the crack .
  3. Slowly squeeze the caulk into the biggest part of the crack with a caulk tube or gun . Move steadily while you fill in the rest. [7]
    • If you don’t think you can get a smooth line in one try, use urethane acrylic caulk . It’s easier to clean up, and you can apply a second layer on top if required.
    • Wear rubber gloves while working with silicone caulk.
  4. Use a spatula to get rid of the excess caulk, then smooth and flatten the line with a piece of hard plastic or your wet index finger. Repeat the process until the chip or crack is level with the rest of the countertop. [8]
  5. Once the crack is filled, remove the tape and allow the caulk to cure for the amount of time specified by the manufacturer. [9]
    • Gently scrape off any dried excess caulk with a razor blade.

Using a Light-Cure Quartz Repair Kit

  1. Take the filling material out of your quartz repair kit (it’s often in a syringe), and put on a tip, if needed. Squeeze the filler into the chip until it’s completely full. [10]
  2. Place a curing strip, or thin sheet of plastic, over the chip. The strip presses the material into the hole and ensures that the area is totally flat. Smooth everything down by running a popsicle stick or coffee stirrer over the strip. [11]
  3. Light-cure repairs use—you guessed it—light to harden the material filling the crack. Take the light from your kit, put it in its stand, and position it over the chip. Turn on the light and let it sit for 5-10 minutes. [12]
    • Get the light as close as you can without touching the curing strip.
    • When the acrylic feels hard to the touch, it’s done curing. If it feels at all soft or tacky, keep it under the light.
  4. Once the acrylic has cured, wipe the area down with rubbing alcohol, and check to see if the surface is completely flat. If it isn’t, use the sandpaper from your kit to rub off excess acrylic, put a few drops of water on it, then use a superfine polishing sandpaper to smooth everything out. [13]
    • Sand your countertop very lightly—using too much pressure can scratch the surface.
    • Polish the area with a fine grit paste, if your kit includes it.

Preventing Cracks and Chips

  1. Quartz can be damaged by sharp objects, so never cut food directly on it. Instead, use a cutting board. [14]
  2. Although quartz can withstand heat for a while, quick temperature changes can cause your countertop to crack. If you’ve got an icy pitcher of water or a hot pan from the stove, don’t put it directly on the counter. [15]
  3. If you keep heavy things (like pots and pans or filled fruit bowls) on your countertop, it’s likely to form cracks at the edges. [16] Decorate your counters with lightweight things instead, and be careful when moving things around, especially in the kitchen. Countertops can chip if they’re hit with a heavy pan.
    • If you have to put something heavy on the countertop—say, a stand mixer—set it down gently. Dropping something heavy can immediately form a crack or chip. [17]
  4. Quartz countertops are made with resin, so abrasive or acidic cleaners can break down the sealant and cause cracks. Use soapy water to clean your counters, instead. [18]
  5. If a countertop is installed poorly there’s a much higher risk of it getting chipped. Always hire a professional to do the work. Not only are they trained to put in countertops correctly, but they also know which materials are best to use and hold up the longest. [19]

      Tips

      • Your countertop may also be under warranty, so contact the company or contractor who installed your countertops to see if they’ll repair any chips or cracks. [20] If your chip was caused by bad workmanship during installation, there’s a very high chance you can get it fixed for free. If you’re not under warranty, the manufacturer can still help by telling you the best methods to fix your chip.

      About This Article

      Article Summary X

      To fix a minor chip in a quartz countertop, first clean the surface around the chip with an ammonia-based cleaner. Once the counter is dry, surround the chip with masking tape to protect the area around it. If your counter is made of light-colored quartz, fill in the chip with a small amount of superglue. For dark or textured countertops, use a pigmented epoxy that matches the color of your counter instead. Apply the glue or epoxy in thin layers with a brush or spatula and give it at least 24 hours to cure before using that part of the counter again. Once the adhesive dries, sand it down with a 360-600 grit sandpaper. For more tips from our DIY co-author, including how to prevent adhesive stains when fixing a chip, read on!
