Protect and perfect
Use masking tape to cover off valves and pipe work, and pop a dust sheet underneath the radiator to catch any stray paint drops. Then, get painting: start at the edges, then paint the face in a vertical direction using long, sweeping brush strokes to get a neat, even finish. Leave for at least six hours before applying a second coat, then allow to dry fully before turning on the radiator.
And there you have it, the best way to paint a radiator according to Dr Dulux. Try it for yourself and let us know how you get on by using #feelgoodcolour on social.
