How to Polish a Cut Edge of Quartz Countertops

Polishing the cut edge of quartz countertops helps improve their appearance and prevent chipping or damage over time. With some simple supplies and techniques, you can achieve a smooth, polished edge.

What You’ll Need

  • Sandpaper – Start with a coarse grit like 60 or 80 and work up to at least 400 grit.
  • Polishing pads – Use a 3-step pad system from coarse to fine.
  • Polish cream – Select a quality cream made for polishing stone.
  • Soft rags – Cotton or microfiber work best.
  • Respirator – To avoid breathing sanding dust.
  • Eye protection – Safety glasses or goggles.

Step 1 – Sand the Edge

  • Put on your respirator and eye protection.
  • Start sanding with your coarsest grit sandpaper, like 60 grit. Sand in long strokes along the edge.
  • Work your way up through the grits, like 80, 120, 220, finishing with at least 400 grit.
  • Sand until the edge feels smooth and any cut marks from fabrication are removed.
  • Wipe away dust with a damp rag after sanding.

Step 2 – Polish With Pads

  • Take your 3-step polishing pad set and start with the coarsest pad first.
  • Apply polish cream to the pad then work it along the edge in circles.
  • Use steady, moderate pressure as you polish. Too much pressure can damage the edge.
  • Polish the entire edge until it looks uniform.
  • Repeat with your medium polishing pad, adding more polish as needed.
  • Finish polishing with your fine pad for a smooth, glossy look.

Step 3 – Clean and Inspect

  • Carefully wipe away any remaining polish with a clean, soft rag.
  • Rinse the edge with water and dry thoroughly.
  • Inspect the edge at different angles to check for a consistent polish.
  • Look closely for any remaining dull spots and repolish if needed.


  • Work slowly and methodically for best results. Rushing can leave swirls.
  • Keep your polishing pads clean as you work. Built-up residue can scratch.
  • Change pads often to prevent heat buildup and edge damage.
  • For tough spots, use a hand applicator with polish instead of a power tool.
  • Consider sealing the polished edge to protect from staining and etching.

Polishing your quartz countertop edges takes time and elbow grease but is worth the effort for an attractive, finished look. With the right supplies and techniques, you can achieve smooth, professional results. Be sure to thoroughly clean and inspect your work when done. Enjoy your revitalized countertops!
