Best Paint for Cast Iron Radiators & Radiator Pipes

We all know the feeling. You move into a newly rented apartment or just complete on a house purchase. You walk into your new abode and notice the radiators and the radiator pipes. Chances are they do not fill you with pride as your new home does.

You might notice pipes sticking out of the floor or running along skirting boards. Or it might just be wall-hung radiators that are could do with a change.

Changing radiators, however, is probably the last thing on your mind when you think of all the expenses you will need to deal with. Relaying carpets, painting walls, replacing doors, kitchen accessories and in some cases, updating your home security system.

So how do you save on the cost of replacing your radiators in the short term? In some cases, just sourcing for the best paint for cast iron radiators and radiator pipes will do the job.

In most cases, you do not even need to remove the radiators from the wall to get it properly painted. If you do need to do one thing though, you need to make sure the radiators are completely cold prior to getting your paintbrushes out.

With that said, let's have a look at the options for the best paint for cast iron radiators and radiator pipes.

It evenly coats over water-filled household radiators and hot water pipes. One of the key things you need to look out for is paint that will remain the colour it is when first painted. This easy to use paint resists yellowing and helps avoid rust formation.

In a lot of cases, metallic paint often comes with a strong smell and you would need to have your windows and doors open after painting. That's not the case with the Hammerite Radiator Paint. It has a low odour and can be dry to touch in between 4 – 6 hours.

Unlike conventional metal paint, Hammerite can be painted directly onto rusty surfaces. No primer or undercoat is needed and the long-lasting rust protection makes not just cast iron radiators to look great but also gates and railings

Unlike the Hammerite Radiator Paint above, this Ronseal One Coat paint has a slightly stronger smell to it. As with most radiator paints, it is also heat resistant so will not crack or change colour when the radiators are in use.

The tough and durable finish you get also protects it against everyday scuffs and scratches. You won't notice the typical scuffs and scratches that come with freshly painted radiators following a few weeks of use as the finish can withstand that. Surprising, considering that no primer is required.

The procedure for applying the paint is not too dissimilar from other paints. You just need to stir the paint thoroughly prior to use. You then need to apply 1 – 2 coats of the metallic paint using a suitable brush or roller.
