How to Finish Quartz Countertop Edges

Selecting the Edge Profile

There are several edge profiles to choose from when installing quartz countertops:

Standard Squared Edge

This simple square edge has a 90-degree angle. It offers a clean, contemporary look. The sharp edges can be prone to chipping over time.

Beveled Edge

The top edge is angled for a softer, more finished appearance. Beveled edges range from 1/16” to 1/2” wide. A narrow bevel is less prone to chipping.

Bullnose Edge

The top and bottom edges are rounded off, creating a curved profile. Bullnose edges have no sharp corners and create a stylish, upscale look.

Ogee Edge

This edge has an elegant S-shaped curved profile. Ogee edges create a high-end, decorative appearance well-suited for traditional kitchens.

Dupont Edge

The Dupont edge has a small lip that overhangs the side edge slightly. It provides increased durability and impact resistance.

Fuller Edge

Fuller edges feature a rounded top edge that overhangs the side edge. It creates a noticeable shadow line for a distinctive look.

Preparing the Edges

Once the edge style is selected, proper preparation is essential:

  • Inspect the edges for any gaps, chips, or irregularities. Fill any small gaps with clear epoxy resin filler.
  • Sand the cut edges smoothly with 120 to 220 grit sandpaper. This removes any saw marks or roughness.
  • Clean the edges thoroughly to remove dust and debris. Wipe with denatured alcohol using a clean cloth.

Applying Edge Treatment

There are several options available to treat and finish the edges:

Polished Finish

  • Apply a polishing compound to the edges using a clean cloth. Rub vigorously to create friction and heat.
  • Use progressively finer grits of sandpaper from 400 to 3000 grit for achieving a glossy polished finish.
  • Buff the edges using a polishing wheel or pad. This brings the polish to a smooth, light-reflecting luster.

Oiled Finish

  • Apply a food-safe mineral oil to the edges using a clean cloth. Ensure all surfaces are coated.
  • Allow the oil to soak in for 15-20 minutes. Then thoroughly wipe off any excess oil.
  • Reapply oil periodically to maintain the finish over time. Oiled edges acquire a natural, satiny sheen.

Colored Caulking

  • Purchase colored caulking that matches your quartz countertop color. White, black, gray and almond are commonly available.
  • Run a thin bead of caulking along the seam where the edge meets the counter. Smooth with a wet finger or caulking tool.
  • Allow caulking to cure fully overnight. The caulked seam creates a neat, finished appearance.

Protecting the Finished Edges

To keep quartz edges looking pristine:

  • Use trivets and hot pads under hot cookware to prevent thermal damage.
  • Install a sink-mounted cutting board to protect edges from knives.
  • Avoid using harsh chemicals and acidic cleaners which can etch the surface.
  • Reapply polishing compound periodically to maintain the glossy shine.

With the right edge profile and finishing process, quartz countertops can keep their sleek, contemporary look for many years. Taking steps to protect the finished edges will prevent unnecessary wear and tear. Thoughtful edge treatment allows you to showcase the full beauty of quartz in your kitchen or bath design.
