Painting cast iron radiators
What is the best way of painting cast iron radiators? This article provides a few tips on how to achieve a stunning yet hard-wearing finish on cast iron radiators.
Below are a few tips to achieving a stunning yet hard-wearing finish on cast iron radiators.
1. DON’T power coat!
Some companies offer a powder coating service on cast iron radiators. This method can produce a fabulous finish, BUT... cast iron radiators are not designed to go through the high oven temperatures and prolonged baking process involved in powder coating. Many experts advise against this option as there is a very real risk that the seals between sections will be damaged during baking which will lead to leaking radiators. For this reason, powder coating will invalidate the manufacturer's guarantee on modern cast iron radiators.
2. DO use cellulose or acrylic based paint
There is no need to use expensive specialist radiator paints. You can achieve a perfect finish using cellulose-based paint or acrylic-based spray paint. For instance, car paint is perfect for radiators as it is designed to cope with extremes of temperature and be tough enough to withstand relatively intense wear and tear. If you like the look of powder coating, then a similar looking end result can be achieved by using products like "Plasti-kote"
3. DON’T use water based paint
If you use water based paint on cast iron you will almost certainly end up with orange “rust blooms”. Some “specialist”
4. DO spray paint rather than brush paint
Cast iron’s textured finish is forgiving, so a good paint finish is easily achievable. If you are planning on painting the radiators yourself by hand, then we recommend using spray paint as it is difficult to reach into the middle columns and achieve a consistent finish using a brush.
