How to prepare your radiator for painting

How often should I repaint my radiators? When painting your radiators, some people find they need to do this every few years because of wear and tear during use but others would say once is enough after ten years or so. It really depends on how much time you spend inside them too – if they’re not used very frequently then one coat will be sufficient for many years. However, if the walls are constantly being touched by hands then two coats may be necessary more regularly than someone

  • Use an old rag or paper towels to remove any dust and dirt from your radiators before you paint them.
  • If there is a matt finish on the radiator, it’s best to use hot water mixed with dishwashing liquid (or another gentle cleaner) in order to loosen up any of the dirt that might be stuck in between the pores of the metal.
  • Wash away as much soap as possible without using excessive force so as not to scratch anything. Let dry completely before painting.
  • Fix any leaks, rust, or cracks with putty and wire wool.
  • Remove the radiator’s paint with sandpaper. Make sure to cover your floor in newspaper before you start so that it doesn’t get scratched!

Painting tips

  • Purchase high-quality paint. Cheap paint will not cover up the old, unattractive radiator and might even peel off if it is sprayed too thinly!
  • Paint over an area that you don’t mind getting messy – like in your garage or driveway. For those who have cats or other pets at home, consider painting outside as well to avoid any damage inside the house while spraying.
  • Use only light colors when using radiator spray paint with dark radiators for best results with minimal effort (obviously this doesn’t work for white radiators). Darker colors are harder to get rid of once applied so we recommend going lighter on these surfaces instead.
  • Variety is key: experiment with different shades and tones of color by exploring
  • Unplug the radiator, if possible. This will reduce the risk of electric shock while painting and make it easier to move when dry. It also provides more space for working on your project without worrying about cords getting in your way, but only do this with a cool radiator! Letting it run at full heat can damage its components.
  • Use painter’s masking tape or blue painters’ paper taping over any openings like vents and outlets before you start spraying paint – as well as covering nearby furniture, floors, etc., that might get covered in overspray
  • The best time to spray is most likely during warmer times of day: early morning hours (between six and nine) or late evening hours (

Spray painting a radiator in 3 easy steps

  • Clean the radiator with soap and water before painting. Make sure there is no dirt or oil on it! The paint will not adhere properly to an unclean surface, so make sure you are starting off right by cleaning your radiators first.
  • Spray a light layer of primer onto the metal surfaces of the radiator. This step seals any rust stains that may be present and helps prevent flakes in new coatings from coming loose over time.
  • Apply two coats of spray paint within 12 hours after applying primer to ensure best results for durability and aesthetics. A second coat also provides more protection against chipping during future use as well as repelling dust & moisture buildup during storage periods when unpainted radiators are stored indoors.
  • Take the radiator outside to make sure it’s in a well-ventilated area.
  • Give your radiators ample time for drying before replacing them inside of your home. Remember that any heat applied can cause warping and crack, so keep those rads out of sight until they’re fully dry!
  • Don’t forget to cover up anything you don’t want to be painted with plastic or newspaper while painting – this will allow for easy clean-up as well as prevent overspray from getting into other areas (such as on furnishings).

Common mistakes when spraying radiators

Mistake #- Never give up! If you’re having trouble getting paint to stick, remember that heat helps. Radiators will dry more quickly if they are heated before painting and then again after the paint has dried for 24 hours.

Tip: A fan can be a great way to keep radiators warm as well – just turn it on an hour or two before spraying your radiator.


Another important thing is making sure there’s no dust sitting atop of the surface to which you want to apply spray paint (in this case, your radiator). Use a vacuum cleaner with attachments such as a brush attachment where possible in order to get rid of any dirt from surfaces prior to using spraypaint; alternatively, wipe

Mistake: Not applying the paint generously

Solution: Spray radiators with plenty of coats to ensure a nice, even finish. Any thin spots in your radiator will be notified when it’s still wet and can only be fixed by adding more layers of color over top.

This short guide on radiator spray paint will definitely help you to make sure that you have a freshly painted radiator that will add more value to your home.
