How to Polish Silestone Quartz Countertops

Silestone is a popular quartz countertop material known for its durability, stain resistance, and stylish appearance. However, like all countertop materials, Silestone requires occasional polishing and buffing to keep it looking its best. Here is a step-by-step guide on how to polish Silestone quartz countertops.

What You’ll Need

  • Polishing pads – Start with a medium grit pad and move up to finer grits. Using a three-step process of medium, fine, and ultrafine pads works well.
  • Polishing compound or polish – Select a product designed for polished stone surfaces.
  • Soft buffing pad – For final buffing.
  • Spray bottle with water
  • Microfiber cloths
  • Rubbing alcohol
  • Painter’s tape

Cleaning Before Polishing

Before polishing, it’s important to thoroughly clean the Silestone counter to remove any dirt, grime, or residues that could interfere with the polishing process.

  • Clear all items from the countertop. Remove any appliances or accessories.
  • Use rubbing alcohol on a microfiber cloth to remove any waxes or polishes already on the surface.
  • Mix a mild detergent with warm water in a spray bottle. Spray the surface and scrub with a soft cloth or sponge.
  • Rinse well and dry completely with a clean towel. Check for any remaining dirt or residues. Re-clean if needed.

Polishing the Surface

With the counters clean, you can begin the polishing steps:

1. Taping and Prepping

  • Use painter’s tape to tape off the edges of the Silestone countertop. This keeps the compounds from getting onto the edges.
  • Vacuum or wipe down the polishing pads to remove any debris.
  • Have your spray bottle of water, polishing compounds, and cloths ready.

2. Polishing with a Medium Grit Pad

  • Apply a dime-sized amount of medium polishing compound to the pad.
  • Working in small sections, use circular motions to buff the Silestone surface. Apply light to medium pressure.
  • Spray a light mist of water as needed to lubricate the polishing.
  • When the section looks enhanced, wipe off any compound residues with a damp microfiber cloth.
  • Repeat over all areas of the countertop.

3. Polishing with a Fine Grit Pad

  • Switch to a fine grit polishing pad.
  • Repeat the process using a fine polishing compound. Work it into the surface using circular motions.
  • Wipe clean with a damp cloth.

4. Final Buffing

  • For an ultra shiny finish, use a soft buffing pad and apply a small amount of polish.
  • Buff the Silestone countertop using light pressure and rapid circular motions.
  • Remove any residue and admire the revitalized finish!

Caring for Polished Silestone

To make your polished Silestone countertops last:

  • Use coasters under glasses and avoid exposing the surface to harsh chemicals.
  • Clean up spills immediately to prevent etching. Use a pH-neutral stone cleaner.
  • Re-apply polishing compounds every 6-12 months to maintain the refreshed look.

Polishing your Silestone quartz countertops helps restore their shine and luster. With the right tools and technique, you can easily achieve professional-looking results. Be sure to keep the surface properly maintained between polishing. Your countertops will continue looking as gorgeous as the day they were installed.

Frequently Asked Questions About Polishing Silestone Quartz Countertops

Can I polish Silestone myself or do I need a professional?

You can absolutely polish Silestone yourself at home. Using the proper polishing pads and compounds, the process is very doable as a DIY project. Going slowly and methodically is key for good results. Hiring a professional may be advisable for large surfaces like full kitchen countertops.

What is the best polish to use on Silestone?

Look for polishing compounds specifically designed for use on polished quartz or engineered stone. Popular options include compounds by StoneTech or GranQuartz. Avoid polishes with abrasive ingredients.

How often should Silestone countertops be polished?

Plan on polishing Silestone about once a year to maintain the best appearance. High-traffic areas may need polishing every 6-9 months for a refreshed look. Polishing yearly helps prevent a buildup of etching or dullness.

Should I work in small sections when polishing?

Yes, it’s best to work in manageable 2-3 foot sections across the Silestone surfaces during each polishing step. This prevents the pads from getting overloaded with residue and allows you to concentrate on small areas. Wipe as you go before moving on.

Can I use a power polisher or buffer on Silestone?

Power polishers are not recommended. The high speeds can cause uneven polishing and may damage the surface. Work by hand using a simple palm sander or hand buffing for best control. Let the compounds do the polishing work.

Will polished Silestone be slippery?

Polishing should not make Silestone noticeably more slippery. The quartz material has good natural traction. As always take care with wet or greasy surfaces. Adding a sealant after polishing can boost slip resistance if desired.


Polishing Silestone quartz countertops helps restore their shine and beauty after daily wear and tear. With the right polishing pads and compounds, it is a manageable DIY project. Be sure to thoroughly clean the surface first and tape off edges. Work methodically in small sections using a medium, fine, and ultrafine grit progression. Annual polishing will keep Silestone surfaces looking their best. Consistent care and maintenance is key for maximizing the longevity of these beautiful quartz countertops.
