Best Radiator Paint Reviewed 2021

best radiator paint

Despite writing this in the middle of a surprisingly warm and humid British summer, where radiators seem about as far from requisite as can be, now is arguably the best time to give them some love and attention. Radiators are the low-key MVPs of the house during the winter. Just think about how good it is to wake up on a cold winter’s morning, only to remember you set the heating to be on by the time you woke up. Or, coming in from the chilly outdoors and being enveloped in the cosy warmth.

All of this romanticising of radiators notwithstanding, they form a big part of our homes nowadays, both figuratively and literally. At a base level, they’re big metal objects on the walls, and how they look can be hugely influential on how the rest of the room looks. A radiator with spots of peeling paint showing the bare metal underneath just comes across as a bit shabby.

Thankfully, specialist radiator paint is not all that hard to find and can be a very simple way to put the finishing touches to a renovated room. However, given that radiators get distinctly hot by nature, you can’t just put any old paint on there, as radiator paints are specially designed with the heat resistance in mind, among other features. So, read on for our summary of the best radiator paints available to buy right now.

Radiator Paint FAQ

How to paint a radiator

First and foremost, make sure the radiator is off and a nearby window is open. Next, thoroughly clean it, using a vacuum cleaner to remove dust from the inside, warm soapy water to clean the surface to be painted, and a long brush to remove any dirt from between the radiator and the wall. Lay something protective down on your flooring, then gently sand the surface of the radiator with alternating high and low grit sandpaper to get rid of surface debris and create an even surface for the paint. Clean any excess dust from the sanding, then prime and paint the radiator with a brush. Make sure you don’t overload the brush with paint, and do long, even strokes. Then, leave to dry for as long as possible (do not turn the radiator on to try speeding up the process).

How to paint behind a radiator

Painting behind a radiator can be very awkward. You can attempt to use a long roller or brush to get in the gap, but ultimately you will struggle to get any further in than around the edges. Removing the radiator is an essential step if you want to do it properly; you may need to drain the radiator, which is a more complex series of steps but will ultimately allow you the best access to the rear of the heater.

How to paint a rusty radiator

The most thorough method to dealing with rusty patches on your radiator involves some coarse grit sandpaper and some time and effort. Sand it thoroughly and use a metal scraper to get all the residue off, then go ahead and apply some radiator paint. Anti-rust primers are available if you’d like an extra layer of protection.

What paint to use on radiators

By and large, as long as a paint is suitable for use on metal (regardless of finish, that’s down to your preference) it can be used on a radiator. Use specialist radiator paint if necessary, which usually comes with superior rust and heat protection.

How to remove paint from radiators

Completely stripping paint from radiators is something that needs to be done thoroughly and with a fair amount of care. Firstly, coarse grit sandpaper is necessary to remove as much paint as possible. Next, apply a good quality paint remover (goggles and gloves are highly recommended!) and leave it for maybe an hour, until the remaining paint has softened and can be scraped off.
