How to Refinish Porcelain Rangetops


If you’re giving your kitchen a make-over and your range top has a few scratches and chips, you can give it a face-lift rather than replace it. Although the glaze on porcelain-enamel appliances varies slightly from manufacturer to manufacturer, stoves are usually finished with a standard “appliance white,” which contains a hint of gray. Even if you have a colored antique stove, surface repair enamel sprays matching all major U.S. appliance manufacturer’s colors are available. Although some finishes react differently to light, with the right techniques, your repairs will blend in perfectly.

Things You'll Need

  • Denatured alcohol
  • Lint-free cloth
  • Small brass wire brush
  • Commercial rust remover (alternative)
  • Porcelain repair kit
  • Newspaper
  • Masking tape
  • Special polishing compound
  • Clean the repair surface thoroughly with denatured alcohol and a lint-free cloth.

  • Scrub any rust off with a small, brass wire brush, or apply a commercial rust remover if there are any signs of rust in the chipped area.

  • Mix up a 2-inch long bead of filler paste with a 3/4-inch bead of the hardener supplied in the porcelain repair kit.

  • Fill the chip indentation completely with mixed filler paste by applying the material carefully with the small wooden spatula provided. Do not overfill the hollow, but feather the edges in smoothly, in preparation for sanding. Allow at least an hour for the material to harden completely.

  • Fold the coarser of the two grades of sandpaper provided into a fairly thick pad. Make the pad flexible enough to follow the surface of the hardened paste without abrading the surrounding enamel. Take your time and sand the repair down carefully until it’s flush with the surface.

  • Sand any remaining surface scratches out with a similar pad of the finer grade sandpaper provided.

  • Wipe the repair down with denatured alcohol and a lint-free cloth to remove all traces of surface dust.

  • Mask off any adjacent fitting or countertop with newspaper and masking tape.

  • Shake the aerosol can of paint provided in the kit vigorously for 30 seconds to mix the contents. Hold the nozzle 5 to 6 inches from the repair. Wipe the spray can sideways so the tip is moving each time you press the nozzle down to start spraying. Apply two or three light dustings of paint with smooth side-to-side strokes, but stop when the surface reflects light from wet paint.

  • Build up three or four thin progressive layers of paint and allow each layer to dry briefly between coats. Hold the can upside down, depress the nozzle to evacuate the tip, and wipe off excess paint from the nozzle between coats; this will prevent marring the surface with droplets of thickened paint.

  • Do not use the stove or touch the repair for 48 hours. Buff off any overspray and polish the repaired surface to a high gloss with the special polishing compound provided by the manufacturers of the porcelain repair kit.
