Quartz countertops are growing in popularity for kitchen and bathroom remodeling projects. Made from crushed quartz combined with resins and pigments, quartz counters are praised for their durability, stain resistance, and low maintenance. However, they are not completely scratch-proof. Over time, normal wear and tear can lead to unsightly marks and scratches. Thankfully, there are some effective DIY methods for repairing superficial scratches on quartz.
What Causes Scratches on Quartz?
While quartz countertops are very durable, they can become scratched by:
- Metal objects like knives, pots, pans, and utensils dragging across the surface
- Appliances with rough or sharp edges
- Dropped glassware, dishes, etc.
- Small rocks and debris under pots/pans
- Cleaning with abrasive pads or powders
Luckily, quartz is non-porous so scratches only affect the surface and not the integrity of the material. Still, scratches are unsightly and should be repaired to restore the look of your counters.
How to Repair Light Scratches on Quartz
Clean the Countertop
Before repairing scratches, thoroughly clean the countertop with a non-abrasive cleaner to remove any dirt or residue. This allows the repair products to work most effectively.
Sand the Scratch Lightly
Use a small piece of extra fine (400-600 grit) sandpaper to lightly sand the length of the scratch. The goal here is to smooth and remove any sharp edges, not deepen the scratch.
Clean and Dry the Area
Wipe away all sanding residue with a dry cloth or paper towel. Make sure the area is perfectly clean and dry.
Apply Countertop Polish
Choose a polishing product specifically formulated for quartz and apply directly to the scratch according to package directions. Rub gently for 30-60 seconds to work the polish into the scratch. Some good options are:
- Stonetech Revitalizer Cleaner and Protector
- Granite Gold Polishing Cream
- HG Quartz Countertop Polish & Touch Up Kit
Buff to Shine
Use a clean, dry microfiber cloth to buff the scratch and surrounding area until it shines. The mild abrasives in the polish should diminish the visibility of the scratch significantly, blending it into the countertop finish.
Repairing Deeper Scratches
For deeper scratches that remain visible, a clear quartz repair kit offers an easy fix:
Clean and Dry the Area
Follow steps above to ensure the area is clean and dry before applying any products.
Fill the Scratch
Apply the adhesive filler directly into the scratch, spreading smoothly with a plastic spreader. Take care not to overfill.
Cure the Filler
Cure times vary, but generally 15-30 minutes under a UV light allows the filler to harden.
Sand and Polish
Once cured, use 400 grit sandpaper to smooth and shape the filler patch, followed by an application of quartz polish to blend.
Clean Up Overfill
For any filler that spreads onto the countertop surface, allow it to cure completely and then carefully scrape off.
How to Avoid Future Scratches
The best approach is to implement preventive measures:
- Use cutting boards and hot pads when prepping food. Never cut directly on the counter.
- Install rubber feet on appliances and furniture to prevent them dragging.
- Avoid abrasive cleaners and scrubbing pads which can damage the surface.
- Clean up spills immediately to prevent staining/etching.
- Always use a trivet under hot pans and dishes.
With proper care and occasional polishing, quartz countertops can remain scratch-free for many years. But superficial scratches are common and can be repaired with the simple, inexpensive methods above.
Frequently Asked Questions About Fixing Quartz Scratches
Can I use automotive scratch repair products on my quartz countertop?
No, auto body repair compounds contain abrasives and chemicals that may damage or stain your quartz. Use only products specifically designed for use on quartz and stone surfaces.
How can I determine if a scratch needs a full repair kit?
Try buffing with quartz polish first to reduce light scratches. If the scratch remains visible afterward or catches your fingernail, then a filler kit is likely needed to fully repair.
Is there an easy way to match the color when repairing a deep scratch?
Clear repair kits allow the natural color of the surrounding quartz to show through, giving an excellent color match. Just take care not to overfill the scratch.
Can any missing pieces along the edges of my quartz countertop be repaired?
For small chips less than 1 inch, the clear filler kits can be used similar to filling a deep scratch. But larger damaged areas may need a professional fabricator/installer to cut and polish a replacement quartz section.
Will boiling water or hot pans permanently damage my quartz?
While extreme, prolonged heat can damage solid surfaces, quartz is designed to withstand normal usage. Using trivets is recommended to prevent cracks or discoloration over time.
