How to Fix Quartz Countertop Scratches

Quartz countertops are renowned for their durability and scratch-resistance. However, even this hardy material can become marred over time. Fortunately, there are several effective methods for repairing superficial scratches on quartz. With a little time and effort, you can restore the pristine look of your quartz countertops.

What Causes Scratches on Quartz?

While quartz is incredibly resilient, it can still get minor scuffs and scratches from daily wear and tear. The main causes of surface-level damage include:

  • Ceramic dishes or glassware scraping across the surface
  • Pots and pans, especially if they have rough bottoms
  • Grit from spills that are wiped across the counter
  • Sharp objects like knives or tools dropping on the quartz
  • Sand, salt or other abrasives left on the counter

Too much pressure from these sources can wear down the glossy finish. However, quartz is less prone to deep gouges than other natural stone due to its engineered construction.

Effective Ways to Repair Quartz Countertop Scratches

1. Use a Buffing Pad

One of the easiest ways to fix light scratches is by gently buffing the area with an abrasive pad. Look for a specially designed polishing pad made for stone surfaces. Apply mild pressure while rubbing the pad in circular motions over the damaged spot. Slowly, this will smooth away the scratch.

Be sure to buff in the direction of the existing stone pattern. Work through progressively finer grits, starting with a 400 or 600 pad. Finish by burnishing with a buffing compound and terry cloth to restore the quartz’s sheen.

2. Try a DIY Repair Kit

For deeper scratches, a store-bought quartz repair kit can work wonders. These contain fillers that are tinted to blend with the countertop color and materials for polishing out defects. Fill small nicks and scrapes as directed on the product’s instructions. Once the filler has fully cured, buff the area until it looks uniform.

Repair kits made specifically for quartz yield the best results. General rock or granite touch-up kits also get the job done. Just ensure it’s formulated for engineered stone.

3. Call a Professional Refinisher

Extensive damage like noticeable gouges or etching across large areas is best fixed by a professional stone fabricator or refinisher. They have commercial-grade tools to grind out and resurface severe damage. This produces a smooth, even appearance across the whole quartz slab.

While pricier than DIY, pro refinishing can tackle flaws that are too large or deep to repair on your own. This restores the structural integrity and Visual appeal of quartz that’s become excessively worn.

Tips for Preventing Scratches

To avoid frequent scratches on your quartz, keep these precautions in mind:

  • Use cutting boards and hot pads when preparing food. Never cut or place hot items directly on the quartz.
  • Clean spills promptly before they have a chance to stain or etch.
  • Apply wax or sealant regularly to increase the surface’s scratch protection.
  • Don’t drag objects across the countertop. Pick them up to relocate them.
  • Ensure furniture legs have felt pads to avoid scratching from sliding.
  • Don’t use abrasive cleaners or scouring pads which can dull the finish.

With proper care and occasional buffing, you can keep quartz counters looking like new for years. But even worn and damaged areas can be renewed with the right materials and techniques. With a few simple repairs, your quartz surfaces can once again become an attractive showpiece in your kitchen or bath.

Frequently Asked Questions About Fixing Quartz Countertop Scratches

Can I buff out scratches myself?

Yes, you can often remove light surface scratches by gently polishing the area using a quartz buffing pad or fine sandpaper up to 2000 grit, applied with mild pressure in circular motions. Finish with a quartz polish to restore the glossy shine.

How do you repair etching on quartz?

For light etching, sand the area with wet 500 grit sandpaper until smooth. Use finer grits up to 2000 to restore polish. Deep etching requires professional refinishing for the best results. Applying an etching repair filler yourself can help improve mild cases.

What is the best scratch remover for quartz?

Look for a specialty quartz scratch remover/repair kit. These contain engineered stone fillers and polishes formulated for quartz. Plastic polish or ceramic cooktop cleaners also work well for light surface fixes. Avoid products with lemon, vinegar or other acids.

Can you use car wax on quartz?

Yes, carnauba wax can be applied to quartz countertops every 2-3 months to enhance stain resistance and shine. Ensure the wax is specially formulated for quartz rather than car paint. Do not use wax polishes containing dyes or silicone oil.

How do you get rid of dull spots on quartz?

Micro-fine sanding using a hand pad or electric sander up to 2000 grit will remove dull spots and restore quartz’s glossy finish. Follow with a stone polish and buffing pad. For hard water spots, use a PH-neutral cleaner made for stone. Avoid acidic cleansers.


Quartz countertops are remarkably resilient, but still prone to minor scuffing and scratching over time. Knowing the proper techniques to repair superficial damage can keep them looking like new. For light scratches, DIY kits and buffing pads often suffice. More dramatic damage requires pro services. With routine care and maintenance, your beautiful quartz surfaces can stay flawless for decades.
