Dulux Quick Dry Gloss Paint - Pure Brilliant White 750Ml Review

Dulux Quick Dry Gloss Paint For Wood And Metal is a good value metal paint that requires no primer or undercoat and is low odour and easy to apply.

The 750ml tin will cover a large surface area and the quick-drying formula and low odour makes this product easy to use. It goes on smoothly and provides a smooth, high shine finish.

This is not as durable as specialist radiator paints. However, it will do the job and smarten up your radiators, though the finish may not stay looking good for quite as long. The paint can also be used on any other metal surfaces around the home and garden making this product versatile.

Overall this is an economical and versatile paint for metal surfaces.

Rust-Oleum AE0060006E8 Spray Paint, Cast Iron Review

Rust-Oleum AE0060006E8 Spray Paint, Cast Iron is a tough, heat resistant enamel paint specially designed for painting radiators. It’s the best radiator paint available if you like a cast iron effect.

This radiator paint goes on fairly well. But for light coloured radiators, several coats may be required. The paint can be recoated several times in the space of an hour, however, after an hour, the paint must be left for 24 hours before recoating.

This radiator paint has a textured finish and a dark grey colour that gives a cast iron effect. You do need to use quite a lot of this product to get a nice finish. However, once completed your radiator will look great and the tough finish will resist rust and stay looking good for years.

This is the best radiator paint for cast iron radiators or to give a cast iron paint effect on any radiator.

Things to Know Before Buying Radiator Paint

If your radiators are looking a little shabby, a lick of paint could be all they need. There’s a huge range of paints on the market in varying colours and finishes to help bring a whole new look to your radiators.

Whether you’re perfecting the finish on an old radiator or you’re after a completely new look altogether, the right radiator paint is key.

If you’re considering purchasing some radiator paint but you’re not sure where to start, the following advice will get you up to speed.

Spray vs Brush Paint

Radiator paint can usually be either brushed or sprayed on, and I’ve recommended both types so you can decide which works best for you.

Most people agree that the easiest type of paint to use is radiator spray paint. The finish is usually just as effective as traditional paint, but there’s no need to remove your radiator from the wall.

Traditional brush paint is a little more effort to apply, but the surrounding area tends to stay cleaner which will save you time. You may find it harder using roll paint to reach certain spots inside the radiator, but it’s far easier to paint thin pipes and small areas. 

Paint Properties

Radiator paint is specifically designed for radiators. It should be heat-resistant, dust-proof, stain-proof, scratch-proof and rust-proof. It should be resistant to temperatures up to 120°C 

While purchasing standard paint may be tempting, it’s highly unlikely to have the same properties as specially made radiator paint. At high temperatures, it may also give off harmful fumes that can damage your health.

Impact on Heat Output

Radiator paint does affect the heat output of your radiator, which means it may take more power to heat the room. You’ll spend more money long term on your heating if the paint dramatically lowers the heat output. 

The shinier your radiator is, the lower heat output it will provide. Matt paint, for this reason, is preferable to gloss paint. Darker colours also tend to produce a higher heat output – matt black is one of the most efficient colour choices. However, as opposed to gloss versus matt, the difference between darker and lighter colours is only around 1%, so relatively insignificant. 

Choosing the Right Colour

Painting your radiator is a chance to make a real style statement! While most people opt for white, there’s no reason not to experiment with different colours to suit the colour scheme of your home. 

Or, if you’re wanting something different but not quite ready to go for bright and bold, a cast iron effect finish is timeless and contemporary.

Radiator Paint FAQ

How To Paint a Radiator

Before painting radiators, turn them off and allow them to cool completely. You should not turn the radiator back on until the paint is completely dry.

You can remove the radiator to make it easier to paint, or you can paint it on the wall.

Clean your radiator thoroughly to remove dust and grease, then lightly sand the radiator to provide a key for the paint to adhere to. Brush it down once more to remove the dust.

You can paint your radiator with any paint suitable for metal surfaces. However, for a longer lasting finish, if you are painting the radiator white, it is advisable to use a specialist radiator paint as this will resist yellowing.

You should protect all surrounding areas and walls with dust sheets and open the windows to provide adequate ventilation. Wear a mask, when applying the paint, especially if you are using a spray formula.

It is best to apply two or more thin coats of paint to prevent drips and an uneven finish. Follow the guidelines on the paint can for recoating times.

How to paint a rusty radiator

If you have large areas of rust or lots of rust spots on your radiator you should sand them thoroughly to remove all of the rust. This may take you back to bare metal, in which case it is advisable to use a metal primer before finishing with the radiator paint of your choice.

How to paint behind a radiator

If you want to paint behind a radiator without removing it from the wall you can use a gloss roller which is smaller than a standard roller and can fit behind the radiator more easily. For difficult corners, you can buy a special radiator brush that has a long, angled handle. Alternatively, you can attach a brush or piece of sponge to a stick with masking tape.
