How to Fix Scratch in Quartz Countertop

Quartz countertops are a popular choice for many homeowners due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can become scratched over time with daily use. Thankfully, there are ways to repair superficial scratches in quartz and restore its original beauty.

What Causes Scratches in Quartz?

Quartz is remarkably scratch resistant, but not entirely scratch proof. Common causes of scratches include:

  • Metal objects like pots, pans, utensils, knives, keys etc rubbing against the surface
  • Appliances dragged across the countertop
  • Sand, grit or other abrasives on the countertop
  • Diamond rings or other jewelry making contact

Deep gouges or chips exposing the resin underlayer typically require professional repair. But small surface scratches can often be fixed with DIY methods.

How to Repair Minor Scratches in Quartz Countertops

Clean the Surface

Before attempting to fix any scratches, thoroughly clean the quartz with a non-abrasive cleaner and soft cloth. This will remove dust, dirt and debris that could interfere with the repair process.

Sand the Scratch Lightly

Use extra fine grit sandpaper (1000 grit or higher) to lightly sand the length of the scratch. The goal here is to reduce the prominence of the scratch, not change the surface level of the quartz. Work slowly and evenly back and forth along the length of the scratch.

Use a Quartz Color Repair Marker

Specialized quartz repair markers are available in colors tailored to common quartz shades. After sanding, clean the surface again and allow to fully dry. Shake the marker vigorously and carefully apply color along the entire scratch, using thin and even coats. Let the marker dry between applications.

Buff the Surface

Once the marker is fully dried, use a soft cloth to gently buff the treated area. This will blend the color for a smooth, uniform appearance.

Apply Quartz Sealer

Finally, apply a smoothing quartz sealer like Countertop Magic to help fill any remaining groove and restore the original shine. Follow product directions for best results.
