How to refinish a radiator

0

Refinishing a radiator requires a specific preparation strategy or the finish will bubble and peel soon after application. Because radiators are metallic, they are ill-suited for adhesion. You must use a primer that can abrade the radiator’s surface to promote adequate paint adhesion. Radiators also require paint that can withstand high temperatures.

Step One

Turn off the radiator. Wait for it to cool.


Step Two

Clean the radiator with the soap and brush. Rinse the radiator and wait for it to dry.


Step Three

Protect areas behind and adjacent to the radiator by covering them with masking paper and a low-tack painter's tape. Cover the floor with a fabric drop cloth.


Step Four

Coat the clean radiator with a high-temperature galvanized metal etching primer. Wait six hours for the primed radiator to cure.


Step Five

Coat the primed radiator with a high-temperature epoxy appliance paint. Wait two hours before removing the masking paper and tape. Wait a full day before running the radiator.
