In this video, This Old House plumbing and heating contractor Richard Trethewey explains how to paint a cast iron radiator.
Steps for Painting a Radiator
- Have the old paint blasted off the radiator by a professional refinish.
- Wipe the radiator clean of all dust and dirt.
- Spray an even coat of primer onto all surfaces of the radiator, including in between the sections.
- Once the primer is dry to the touch, spray on an enamel paint topcoat.
