Most modern radiators have a powder-coated finish, meaning they are paintable. If you have reconditioned vintage radiators, check the existing finish with the supplier. On the other hand, chrome radiators and towel rails are not generally suitable for painting due to the combination of high heat, damp towels and the nature of the surface.
Use a paint that is self-priming, self-sealing, suitable for the surface and able to tolerate heat.
If your radiators have a powder-coated finish or have been previously painted, try one of these Frenchic ranges:
First, completely switch off the radiator several hours before you intend to start, so the surface becomes stone cold prior to painting. The radiators must also stay completely cold for at least 48 hours after your final coat of paint. Keep the area well ventilated for a few days if there’s moisture in the room’s air, such as in a bathroom.
Before painting, clean your radiators with sugar soap and treat any areas of rust. Sand lightly to provide a key and remove any existing flaking paint. Finally, wipe down to remove any dust and paint straight on as described on the tin. Follow the direction of fins or panels, which usually run vertically. Feather in along the top and brush along the top edge from one side to the other.
