Quartz countertops are durable and low-maintenance, but chips and cracks can still occur. Fixing a chipped quartz countertop is possible with the right materials and techniques. Here is a step-by-step guide on how to repair quartz countertop chips.
Assessing the Damage
The first step is to assess the extent of the damage. Small chips, minor cracks, and scratches can often be repaired yourself. However, larger chunks missing or cracks extending across the countertop may require professional help.
Examine the chip closely. Determine its size, depth, and location. Look to see if the chip has caused any subsurface damage. This will help you decide whether it’s a DIY project or time to call in a pro.
Cleaning the Area
Before attempting to fix the chip, clean the area thoroughly. Remove any dirt, debris, oil, or residue from the chipped section. This allows the repair products to properly bond with the quartz.
Use a mild nonabrasive cleaner and soft cloth. Avoid harsh chemicals or scrubbing pads, as they may cause further damage. Rinse well and let the surface dry completely.
Prepping the Chip
Small chips and scratches need some prep work before filling. Carefully scrape out any loose quartz using a putty knife or razor. Vacuum away the debris. This helps the filler adhere properly.
For larger chips, you may need to create a “key.” Use a drill to make small holes at the chip’s corners. This gives the repair compound something to grip and creates a stronger bond.
Filling the Void
There are several options for filling and repairing a chipped quartz countertop:
- Quartz filler putty – Specialty putties available at hardware stores are designed for quartz repairs. They contain quartz-like material and binding resin to blend into the surface.
- Clear epoxy resin – Two-part epoxies work well for filling chips. They dry clear and hard. Colored epoxies can also be used if matched to the quartz.
- Clear silicone – For small dings and scratches, a clear silicone sealant can provide an easier fix. It won’t be quite as durable over time.
Apply multiple thin layers of whichever filler you choose. Allow each layer to partially dry between applications. Overfill slightly to allow for sanding and polishing.
Sanding and Polishing
Once the filler has fully cured per the product instructions, sand and polish the area. Start with 220 grit sandpaper to smooth the filler flush with the surrounding quartz.
Progress up through finer grits like 400, 800, and 1500. Then use a polishing compound and buffing pad to restore the quartz’s glossy finish.
Take care not to sand or polish too aggressively. This can create uneven spots in the finish. Work slowly and blend the repair into the undamaged areas.
Sealing the Repair
For added protection, seal the repaired section with a quartz countertop sealer. These clear sealants fill microscopic pits and form a protective barrier.
Thoroughly clean the sanded/polished area first. Apply 2-3 thin coats of sealer, allowing proper drying time between coats. Buff with a soft cloth for best results.
Precautions When Repairing Quartz Chips
- Work slowly and cautiously to avoid further damage.
- Large repairs may require a pro for structural integrity.
- Match colored putties/epoxies to the existing quartz color.
- Uneven polishing can leave noticeable dull spots.
- Reseal surrounding areas to blend repaired sections.
Tips for Preventing Quartz Countertop Chips
- Use cutting boards and hot pads to protect the surface.
- Avoid dropping heavy, sharp, or hard objects on the quartz.
- Install a sink-front protective cover to prevent chipping near the sink.
- Handle spills quickly to prevent stains that may require aggressive cleaning.
- Have countertops professionally refinished/resealed periodically.
When to Call a Professional
While small chips and dings can often be fixed with a DIY approach, larger damages may require a pro. Seek professional help for:
- Cracks wider than a hairline that extend across the surface.
- Countertop overhangs or corners with broken chunks missing.
- Significant subsurface damage like cracks through the quartz layer.
- Large damaged areas greater than 3-4 inches.
- Damage around sinks/faucets that may impact structural integrity.
- Any repair that requires removing the quartz from the base cabinet.
Quartz is remarkably resilient, and chips don’t necessarily mean you need a whole new countertop. With the right techniques and materials, many chips and cracks can be repaired successfully. Just be sure to assess the severity of damage accurately to determine if it’s a DIY project or time to hire a pro.
Frequently Asked Questions About Fixing Quartz Chips
What is the easiest way to fix a small chip in a quartz countertop?
For minor chips less than 1/4 inch, using a good quality clear silicone sealant is often the easiest repair method. Just thoroughly clean the area, let dry, and fill the chip with silicone. Allow to cure completely and buff smooth.
What kind of epoxy should I use?
Two-part epoxies formulated for quartz or stone repairs work best. Look for ones that cure clear and hard. Colored epoxies can also be used if you get an accurate color match with the existing quartz.
Should I use super glue to mend a chip?
Cyanoacrylate “super” glues are not recommended. They dry opaque white and will be visible in the repair. Plus, super glues are more brittle and won’t last as long as epoxies or quartz-specific fillers.
How long does quartz chip repair take?
Small DIY repairs may take 2-3 hours. Allow proper curing times for fillers and epoxy per the manufacturer. Larger repairs could take 4-6 hours or more, depending on the materials and how much polishing/buffing is required.
Can I repair quartz myself or do I need a pro?
Many chips and scratches can be fixed with DIY methods. But deep cracks, chunks missing, or damage impacting structural stability may require a professional fabrication/installation specialist.
Chips and dings in quartz countertops are inevitable but repairable in many cases. For small damages under 1 inch, using quality fillers and epoxies with proper sanding and polishing techniques can often restore the look of your quartz surface. Seek pro help for cracks over 3-4 inches or damage affecting the underlying structure. With some patience and the right materials, those pesky quartz chips can usually be fixed successfully.
