How To Paint a Radiator

Before painting radiators turn them off and allow them to cool completely. You should not turn the radiator back on until the paint is completely dry.

You can remove the radiator to make it easier to paint, or you can paint it on the wall.

Clean your radiator thoroughly to remove dust and grease, then lightly sand the radiator to provide a key for the paint to adhere to. Brush it down once more to remove the dust.

You can paint your radiator with any paint suitable for metal surfaces. However, for a longer lasting finish, if you are painting the radiator white, it is advisable to use a specialist radiator paint as this will resist yellowing.

You should protect all surrounding areas and walls with dust sheets and open the windows to provide adequate ventilation. Wear a mask, when applying the paint, especially if you are using a spray formula.

It is best to apply two or more thin coats of paint to prevent drips and an uneven finish. Follow the guidelines on the paint can for recoating times.

How to paint a rusty radiator

If you have large areas of rust or lots of rust spots on your radiator you should sand them thoroughly to remove all of the rust. This may take you back to bare metal, in which case it is advisable to use a metal primer before finishing with the radiator paint of your choice.

How to paint behind a radiator

If you want to paint behind a radiator without removing it from the wall you can use a gloss roller which is smaller than a standard roller and can fit behind the radiator more easily. For difficult corners, you can buy a special radiator brush that has a long, angled handle. Alternatively, you can attach a brush or piece of sponge to a stick with masking tape.
