Do it! Spray paint a radiator

1 Make sure the radiator is turned off and cold to the touch. Shake the can of spray paint vigorously for at least a minute. 2 Hold the can around 30cm from the radiator’s surface (protect the wall with newspaper) and spray in a sweeping motion. 3 Don’t be tempted to go over the same area more than once. Instead, aim for two to three coats, leaving 30 minutes between each. 4 Leave the radiator to dry (following the instructions on the can) before turning it back on.
