How to Edge Granite Countertops


When having granite countertops installed, homeowners are generally given options for what sort of edge that they would like. Many people choose a smooth, rounded edge. Others prefer the unfinished edge, because it looks more natural. But it often takes only a few months of scraping arms or catching clothes against the rough granite for those with unfinished edges to wish they had chosen another course. All is not lost; the edges of granite countertops can be softened even after they are already installed.

Things You'll Need

  • Newspaper
  • Tarps
  • Gloves
  • Safety glasses
  • Paper mask or respirator
  • Hand-held stone polisher
  • 150-grit, 300-grit, 500-grit, 800-grit, 1500-grit, and 3000-grit polishing pads
  • Cloth
  • Cover everything that you wish to protect with newspaper and tarps; there will be a bit of a mess. Wear heavy gloves and plastic safety glasses. Place a paper mask or respirator over your nose and mouth.

  • Insert a 150-grit masonry polishing pad into the stone polisher. Press the pad end of the polisher with moderate force against the front edge of the granite at one end. Turn the polisher on and move it evenly over the edge from one end to the other; use a moderate speed if you have the option.

  • Polish the remaining edges with a 150-grit pad, using a new one if the first is worn. Replace the 150-grit pad with a 300-grit pad once you are finished and polish all of the edges again in the same way. Exchange the 300-grit pad for a 500-grit pad and repeat the process.

  • Continue polishing the granite edges with 800-grit, 1500-grit, and 3000-grit pads. Shape a rounded edge while you polish, if desired. Wipe down the countertop well with a damp cloth when you are satisfied with the finished edges.
