Video of the Day

Turn off all power at the circuit breaker.

Sand the surface of the electric heater with 80 to 120 grit sandpaper, effectively abrading it to promote paint adhesion.

Cover the vents and the heating element with blue painter's tape or foil to protect them from paint.

Apply appliance epoxy paint to the electric heater using the 3- to 4-inch paintbrush.

Allow the surface to dry for four hours. Apply another coat.

Allow the surface to dry for four more hours before restoring power.

Tips & Warnings

  • Use only appliance epoxy to paint an electric heater. Do not use other types of latex or oil-based paints, because they may present a significant fire danger.
  • Do not attempt to paint a gas-powered heater or a portable space heater.
