Old radiators can sometimes be painted odd colors or just need some freshening up. Painting with a brush can be a bit tedious, so here’s a way to spray them. Use a very large piece of plastic to go behind the radiator and cover as much of the surrounding walls and floor as possible. Cut slits to go around the water pipes and feet and then use painters tape to seal the plastic to the floor. Give the radiator a light sand and thorough cleaning.
Use a spray paint designed for metal in a new color of your choice.
Open as many windows as possible and wear a mask. Give the radiator 3 light coats. Trying to put too much paint on in each coat will result in runs in the paint.
Beautiful new-looking radiator!
