Painting Rusted Baseboard Heaters
- 1). Remove the baseboard heating cover, unscrewing the fasteners, leaving only the heating element attached to the wall. Usually, a baseboard heater has two removable sections.
- 2). Sand the entire baseboard heater cover with steel wool to remove the rusty areas.
- 3). Brush on a rust-removing product containing phosphoric acid on any remaining rust. The rust will darken and undergo a chemical reaction that allows paint to easily adhere to the heater cover surface.
- 4). Apply metal primer to all the surfaces of the baseboard heater cover with a bristle or sponge brush. Let the primer dry.
- 5). Coat the cover with protective enamel paint or metal paint. Reattach the cover to the wall.
