How to Sharpen on Quartz Countertops

Quartz countertops are popular in many homes today thanks to their durability, easy maintenance, and stylish appearance. However, like all countertops, quartz will become dull over time with use. Sharpening quartz countertops helps restore their luster and functionality. Here is a detailed guide on how to properly sharpen quartz countertop surfaces.

Methods for Sharpening Quartz Countertops

There are a few effective methods for sharpening and polishing quartz countertops:

Using a Countertop Polishing Kit

Specialized countertop polishing kits are available with everything needed to polish and sharpen quartz surfaces. They typically include a polishing compound or cream along with a buffing pad and sometimes a hone tool.

Follow the kit directions to evenly apply the polishing cream across the countertop surface using circular motions. Use the included buffing pad to work the polishing compound into the quartz. This process helps remove dullness, etch marks, and light scratches. Rinse the surface afterwards.

Kits with honing tools can further sharpen countertops by grinding down any remaining etch marks and imperfections. Use the hone after polishing.

Sanding and Polishing Pads

Wet sanding with fine grit sandpaper can effectively sharpen quartz countertops. Start with a 600 grit paper and work up to 3000 grit for best results. Always sand in a circular motion. Keep the surface wet while sanding to prevent dust buildup.

Follow with a buffing pad and polishing compound to restore the smooth finish. Use a soft cloth and water to remove residue.

DIY Polishing Cream

For a budget-friendly approach, make your own polish. Mix baking soda and lemon juice into a spreadable paste. Apply the mixture to the countertop and distribute evenly with a soft cloth.

Let it sit for 5 minutes before buffing in circular motions. Rinse thoroughly after polishing. The baking soda acts as a gentle abrasive while the acid in the lemon juice helps brighten the quartz.

Tips for Sharpening Quartz Countertops

  • Thoroughly clean countertops before sharpening to remove dirt, oil, and debris that can hinder results.
  • Work in sections, completing one area before moving to the next. This helps prevent drying or splattering.
  • Apply even pressure as you polish or sand. Too much pressure can damage the surface.
  • Use a plastic putty knife to remove stubborn stains and deposits that don’t lift with polishing. Avoid metal scrapers that could scratch.
  • For honing tools, hold at a 20-30 degree angle and work against the grain. Let the tool do the work.
  • Finishing with a stone sealer helps protect the revitalized finish.
  • Avoid excessive scrubbing, acidic, or abrasive cleaners that can dull quartz over time.
