Buyer Guide / FAQs

What’s the best type of paint for radiators?

When choosing paint for radiators, you will have a choice between oil-based and water-based paints. Oil-based paint generally provides better coverage, durability and heat resistance. It’s the ideal choice when painting metal or other surfaces that will be exposed to high temperatures. However, oil-based paint takes longer to dry so it is better for surfaces that require a smooth finish. 

On the other hand, water-based paint dries quickly and offers great coverage with only one coat of paint. It’s also easier to clean up and more environmentally friendly than oil-based paints. But it isn’t as heat resistant and can turn yellow over time. 

Ultimately, when deciding on which type of paint to use on your radiator, you’ll need to consider the temperature that it will be exposed to and the finished effect that you’re looking for. Both oil-based and water-based paints can provide excellent results with proper application. 

Should radiators use gloss or satin paint?

When it comes to deciding between gloss or satin paint for radiators, the choice can seem overwhelming. The main differences between the two finishes are that gloss paint provides a bright, shiny finish and is easier to clean, while satin paint has more of an eggshell-like sheen and usually hides imperfections better. 

Gloss paint works well in modern, contemporary interiors and is ideal for adding a bit of glamour or luxury to a room. On the other hand, satin paint is better suited to traditional or classic interior styles as it adds a subtle warmth to the space. Whichever type you choose, both finishes will add character and colour to your radiators while protecting them from heat and dust. 

Do I need to prime a radiator before painting?

Priming helps create a better bond between the radiator and the new coat of paint, making it last longer and look better. It also creates a smoother surface for the application of paint, reducing brush strokes or drips that can ruin the appearance. 

Regardless of the method used to paint your radiators, make sure that you follow any safety guidelines recommended by manufacturers to ensure a safe job. With a little patience and attention to detail, you can achieve beautiful results that last for years.

What colour radiators give off the most heat?

With the current cost of living crisis, many people are trying to save energy wherever they can. One way you may have considered doing this is by changing the colour of your radiators – but does it really make a difference? The truth is that while the colour of your radiator might impact how quickly the room heats up, it won’t affect the amount of heat your radiators give off.

So, if you’re looking to save energy and reduce the cost of your bills, it’s better to invest in efficient heating appliances rather than worrying about the colour of your radiators.
