An equally effective and less expensive method of updating the kitchen is to refinish the cabinetry. Before a beautiful new look can be applied, the old polyurethane finish has be removed.

Things You Will Need

  • Screwdriver
  • Masking tape
  • Marker
  • 2 plastic drop cloths
  • Face mask
  • Gloves
  • Paint brush
  • Gel stripping agent
  • Putty knife
  • Steel wool
  • Toothbrush
  • Cotton cloth
  • Sander and 220-grit sandpaper

Preparation

  1. Remove all doors, drawers, hinges, handles and knobs. Use a screwdriver to remove the screws, twisting in a counterclockwise direction. Use a marker and a small piece of masking tape to label each drawer and cabinet door with a designated symbol that indicates where they go when finished. Save all hardware and screws in a convenient location.

  2. Place a drop cloth over the floor in a well-ventilated area you have picked to strip the polyurethane off the cabinets. Set all doors and drawers on the plastic in the order you wish to complete them.

  3. Place a drop cloth over all counters directly beneath the cabinets you will be using the stripping agent on. Secure it in place using masking tape.

Stripping the Finish

  1. Put on a face mask and protective gloves. Apply an even, thin layer of gel stripping agent to small areas of the finish on the cabinets using a paint brush. Wait a few minutes for the gel to begin working. The polyurethane finish will start to bubble up.

  2. Hold the putty knife down toward the wood surface at a 45-degree angle. Begin carefully scraping the polyurethane and stripper from the wood. Scrape with the grain of the wood to avoid gouges.

  3. Dip a steel wool pad and toothbrush in stripper to finish scrubbing away areas of polyurethane that seem to not want to budge. Allow the surface a few hours to dry.

  4. Use a small belt or palm sander with 220-grit sandpaper to smooth the surface and remove all leftover stripper. Wipe the surface with a damp cotton cloth to remove any remaining dust.
