Can a Broken Quartz Countertop be Repaired?

While quartz countertops are durable, they can sometimes crack. While it can be frustrating, don’t panic. Knowing how to prevent and fix cracks helps maintain your quartz countertop and also prevent further cracking.  

What causes cracks on a quartz countertop?  

• Quartz countertops are durable. However, if you are not careful, you may start noticing cracks, dark patches and even fissures.  
• Cracks may be caused by sudden changes in temperature. Keep heat protectors and trivets on hand to avoid placing a hot pot directly on the surface. 

• Throwing objects such as car keys or spoons on your quartz countertops, may cause cracks.  
• Some quartz countertops, especially those of lesser quality, can crack if suddenly exposed to cold. Avoid placing an ice bag directly on your quartz countertop.  

Can you repair a quartz countertop? 

Quartz countertop repair is a simple process. You will need an acrylic adhesive, epoxy or a clear resin. For better results, ensure you only use a fast-setting clear epoxy. This dries to a hard consistency and also blends with the surrounding quartz stone.  

Before you begin to repair your quartz countertop, check whether the warranty is still in place. If the warranty is still in place, check the types of damages that the provider covers. Most quartz warranties last between 1-10 years, depending on the type and cause of damage. If the damage is still covered, contact your provider and ask for help. They can send someone to fix the damage or give you simple instructions, especially if the crack is minor.  

If your quartz countertop has a large crack, it is wise to have a professional fix it. While this can be costly, depending on the intensity of the crack, you are ensured a flawless finish.  

Here is a guide on how to repair a quartz countertop  

1. Examine the damage 

Different damage extents require different filling techniques. This is why it is important to consider the location of the crack before purchasing your glue. If the damage is on a horizontal surface, a thinner glue is the best choice. If the damage is on a vertical surface, a thicker glue is a better choice to avoid drips.  

2. Ensure you are working on a clean countertop 

Attempting to seal a crack on a dirty countertop will not give you the desired results. Use a recommended cleaner prior to the repair and give more attention to the area around the chip or crack. Ensure the entire countertop is dry before you start filling the cracks. Acetone is also an excellent countertop cleaner prior to filling. Allow the acetone to evaporate before proceeding. 

3. Mask the cracked area 

To prevent the glue from flowing to other parts of the countertop, use tape to surround the cracked area. Failure to mark the cracked area will allow the glue to flow to the entire countertop and produce inconsistent results.  

4. Fill in the cracks with the acrylic adhesive, epoxy or the clear resin 

Apply the resin to the broken area and ensure it spreads evenly. Do not use your bare hands to spread the glue. Opt for a toothpick or a paintbrush. The choice of epoxy should be based on the colour of your countertop. 

If it is a small crack, place the tip of the glue on the crack and squeeze the tube. For better results, use thin layers of glue as opposed to filling the entire crack with the glue at once. Let the layers dry before adding the next layer.   

5. Wait for it to dry 

Waiting for a countertop to dry seems simple. However, in a multifunctional space, it can be more difficult than expected. Using your countertop before the epoxy dries could ruin the results. Give up to 24 hours for the epoxy to dry.  

6. Scrape away excess epoxy 

Ensure that the epoxy is completely dry before removing the tape and scraping the excess glue. To ensure the filled space matched the rest of the countertop, fine sandpaper should smoothen it out. 

Now that you have repaired your quartz countertop, you must take damage preventive measures. Here are ways to enhance the maintenance of your quartz countertop and ensure durability: 

• Your quartz countertop is not a chopping board– Using your quartz countertop as a chopping board is a direct invitation for cracks.  
• Do not place hot objects on the countertop– It may be made of tough material, but quartz is not heat resistant. Placing hot objects on the countertop makes it susceptible to cracks and heat patches. Check out this article for more information about taking care of your quartz countertop. 
• Do not spill acidic substances on your quartz countertops. If a spill accident occurs, be sure to wipe the spills immediately.  
• To maintain the shine of your countertop, avoid using an abrasive material to clean the countertop. Use gentle cleaning sponges to clean the countertops.  
• Do not use strong chemicals on your quartz countertop. For instance, using bleach, acetone or paint remover to remove stains only worsens the situation.  
• To clean your quartz countertop, use mild soap and a soft sponge. If your countertop sustains tougher stains, use an oil-based solution or glass cleaner to wipe it off.  

Evade further cracks on your newly repaired quartz countertop by avoiding dropping heavy objects on it or sitting or standing on it.
