Radiator paint buying guide

Radiator paint is made of a special formula designed to be rust-proof, heat-resistant, dust-proof, stain-proof and scratch-proof. It is resistant to temperatures of up to 120°C. Radiator paint is most commonly white but can come in a range of colours and finishes.

Radiator paint and safety

It's important to do your research when you want to repaint a radiator in terms of safety (i.e. risk of fire) and health.

You cannot paint a radiator with just any kind of paint as many will give off harmful fumes. To avoid any risks, it is essential to use a specially designed, long-lasting radiator paint.

Radiator paint usually has a white finish which will blend into most interiors when decorating. If you do want to go for a different colour, it's worth noting that darker colours will emit more heat.

The same goes for the paint finish: a matte paint will release more heat than a gloss or satin paint.

Cast iron radiator paint

Cast iron radiators are usually powered by central heating and should be painted using a high-quality rust-proof paint. You can choose between a solvent-based oil paint or a water-based paint. If the radiator has already been painted and is discoloured, be sure that the paint is not peeling away before you reapply.

Electric radiator paint

It is possible to paint some types of electric radiator, though you must check the manufacturer's recommendations. It is best to apply a coat of water-based paint in this case. You may be able to use a cast iron radiator paint, provided you check the paint components before purchasing. Bear in mind that water-based paints release fewer VOCs when drying. If using a water-based paint, your painting tools can be cleaned using water.

Radiator spray paint

The benefit of using a spray paint is that it is able to reach easily into all nooks and crannies and is quick-drying. It also adheres well to all surfaces as long as they are clean and not chipped. Another advantage: you don't have to use any tools so there is no need for cleaning and drying your brushes and rollers!

However, radiator spray paint is not without its drawbacks; for example, it is a good idea to protect the surrounding area to prevent any paint transfer when you spray. You'll therefore have to use protective tarp and masking tape.

Flat radiators are, of course, easier for painting. However, most radiators feature fins. But don't worry: as long as you've got the right tools, painting a radiator should be a doddle. You'll need:

• edging paint brush;

• flat paint brush;

• radiator paint brush (long with right-angled brush head);

• roller;

• wire brush;

• masking tape;

• protective tarp.
