Overtime, radiators can begin to flake or discolour, which can ruin the overall appearance of the room. Rather than replacing the radiator, you can provide it with a new lease of life with one of the recommendations above.

All of the radiator paints listed are suitable for water-filled radiators and other metal surfaces. To avoid disappointment, we strongly recommend waiting at least 24 hours before turning the radiators on. This gives the paint enough time to fully dry and provide a high quality finish upon the radiator.
