Many people are surprised to learn that they can liven up their drab electric heaters by applying a coat of paint. However, whether you have heaters that run along a baseboard or you have a standard box heater, you need to know the appropriate materials to use and the techniques to apply them or you may create a very dangerous situation.

Things You'll Need

  • 80 to 120 grit sandpaper

  • Blue painter's tape

  • Aluminum foil

  • Appliance epoxy paint

  • 3- to 4-inch paintbrush

Step 1

Turn off all power at the circuit breaker.

Step 2

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

Step 3

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

Step 4

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

Step 5

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

Step 6

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


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.
