How to Buff Out Quartz Countertop

Quartz countertops are a popular choice for many homes due to their durability, aesthetics, and low maintenance. However, like all countertop materials, quartz can become scratched and damaged over time. Learning how to properly buff out superficial scratches in quartz can help restore its original beauty. Here is a detailed guide on how to buff out quartz countertop surfaces.

What You Need to Buff Out Scratches in Quartz

Buffing out light scratches in quartz requires using the right tools and materials. Here is what you will need:

  • Quartz polish or sealant – Use a high-quality polish made specifically for quartz. Avoid polishes with acidic ingredients.
  • Microfiber cloths – These are perfect for applying and removing polish. Make sure they are lint-free.
  • Soft buffing pad – Choose a fine, smooth pad that can buff the quartz gently. Avoid stiff abrasive pads.
  • Orbital sander (optional) – For buffing large surface areas, an orbital sander with variable speeds can help. Use a soft pad.
  • Masking tape – To protect areas not being buffed.
  • Isopropyl alcohol – For cleaning the surface before and after buffing.
  • Water – For rinsing residue after buffing.

Assessing the Damage

Before buffing, inspect the scratches carefully. Quartz can withstand a good deal of abuse without showing damage. Light superficial scratches may disappear with just cleaning and polishing.

Consider the depth and severity of scratches:

  • Fine hairline scratches – These are surface level and can be removed by buffing and polishing.
  • Medium scratches – Slightly deeper but can still be smoothed out through gentle buffing.
  • Heavy scratches and gouges – Significantly deeper and more severe. May require professional repair or replacement.

Always try the gentlest approach first before attempting heavy buffing. Harsh buffing can damage the quartz surface further.

Steps to Buffing Light Scratches

Follow these steps to properly buff out minor scratches in quartz:

1. Clean and Dry the Surface

  • Wipe down the countertop with isopropyl alcohol using a microfiber cloth. This will remove any dirt or debris.
  • Allow the surface to dry completely. Buffing agents work best on clean, dry quartz.

2. Apply Buffing Polish

  • Put a small amount of quartz polish or sealant on a clean microfiber cloth.
  • Rub the polish directly onto the scratches using smooth circular motions.
  • Apply evenly over scratches and a small surrounding area. Don’t over apply.

3. Let the Polish Sit

  • Allow the buffing polish or sealant to sit on the surface for 5-10 minutes. This allows active ingredients to penetrate.
  • Avoid letting polish dry completely. Keep the surface moist if needed.

4. Buff the Surface

  • Using a soft buffing pad, buff the polish gently over the scratches.
  • Apply light pressure and keep the pad moving constantly.
  • Buff in the direction of the scratches to help diminish their appearance.
  • Add more polish as needed and re-buff until scratches are less noticeable.

5. Remove Residue and Reseal

  • Use a clean, dry microfiber cloth to remove all polish residue.
  • Rinse with water and dry completely.
  • Apply a thin coat of quartz sealant evenly over the surface.
  • Allow sealant to dry then buff again with a dry cloth until smooth.

6. Inspect and Repeat if Needed

  • Carefully inspect the buffed area for remaining scratches.
  • Repeat steps as needed until scratches have disappeared or are barely visible.
  • Take care not to over buff as this can damage the surface.

Tips for Buffing Out Quartz Successfully

  • Work in good lighting to properly inspect scratches before and after buffing.
  • Address scratches soon after they occur as polish works best on fresh damage.
  • Move slowly and gently especially around edges and seams which can chip if over buffed.
  • Choose a quartz-specific polish as products with acidic ingredients can etch the surface.
  • Use lighter pressure and minimal product when buffing out fine scratches.
  • For heavy duty buffing, use an orbital sander on the lowest speed setting.
  • Mask off surrounding areas with painter’s tape to avoid damaging adjacent surfaces.
  • Rinse residue after buffing thoroughly. Left over product can cloud the quartz over time.

When to Call a Professional

While minor scratches can often be buffed out DIY, deeper damage may require a professional fabricator. Seek professional help for:

  • Heavy gouges or chips extending deep into the stone.
  • Extensive scratching over a large surface area.
  • Damage around sinks, faucets or seams that may require seam restoration.
  • Matching buffed areas to the surrounding quartz if discoloration occurs.
  • Securing replacement quartz if damage is beyond repair.

Maintaining Your Quartz Surface

To keep your quartz looking its best:

  • Use cutting boards and trivets to protect from cut and heat marks.
  • Clean spills promptly to avoid stains setting in.
  • Avoid using abrasive cleaners or scouring pads which can scratch.
  • Reseal quartz every 1-2 years to reinforce stain resistance.
  • Have any damage professionally repaired as soon as possible.

With proper care and maintenance, quartz countertops can remain resilient and beautiful for years before needing replacement. Learning how to buff out superficial scratches and dings can help extend its lifespan. Follow these buffing techniques carefully to restore the smooth factory finish.

Frequently Asked Questions About Buffing Out Quartz

Can I use any polish to buff out quartz?

No, you should use a polish specifically formulated for quartz. Acidic polishes like those for marble or limestone can etch quartz. Opt for a pH neutral quartz polish.

How can I tell if a scratch can be buffed out?

Run your fingers over the scratch gently. If you can’t catch a fingernail on it, it is likely a surface scratch that can be smoothed by buffing and polishing. Deeper gouges usually require professional help.

Should I completely reseal my quartz after buffing out scratches?

It’s not necessary to completely reseal the entire surface. Simply apply a thin coat of sealant over the buffed areas and surrounding areas once buffing is complete.

Can I use a buffing pad on my power drill?

A power drill buffing pad often moves too aggressively for quartz. Opt for a variable speed orbital sander or buff by hand instead to control the pressure.

Is it okay to buff across the direction of scratches?

Buffing across scratches can worsen their appearance. Always buff in the same direction as the scratches to diminish the look of damage.


With its durability and minimal maintenance, quartz makes an excellent choice for busy kitchens and baths. Minor scratching and scuffing over time is unavoidable. By following these steps for how to buff out quartz countertop surfaces, light superficial damage can be minimized to keep quartz looking its best for years. Handle deep scratches with care and rely on a professional fabricator as needed. With the right techniques, you can retain the natural beauty of quartz surfaces.
