Which paint should I choose for a radiator?


Radiators are certainly the most unconventional supports that can exist: their shape but also their support can lead to many questions concerning their painting.


First of all, it is important to keep in mind that beyond the nature of the difficult funds (cast iron or metal), it is a support which can heat up to several tens of degrees, it is therefore important to choose carefully the type of paint which will be applied to the support in order to ensure its durability on the coating.


Acrylic paint and epoxy paints are often cited alternatives, but it is sometimes possible to paint your heater with more conventional multi-surface products.


This is particularly the case with Algo paints, which are perfectly suited to radiators. While the Algo range is primarily made up of algae, natural elements, and water, it is also perfectly suited to radiators.


In order to use our paint on your radiator and therefore promote a more natural and ecological alternative, you will need to apply a coat of primer dedicated to metal and high temperatures before applying the finish.


Once the primer is applied, it will then be entirely possible to use our paint and one of our 100 shades.


When it comes to choosing the finish, we recommend a satin or velvety finish to ensure the best possible maintenance.


How to paint a cast iron radiator?


Once you have chosen the paint, you must prepare your surface for renovation.


Prepare your radiator


The first step before starting your project is to dismantle your cast iron radiator so that you can repaint it in its entirety, even in inaccessible corners, and also to protect your walls (especially if you are going to use a particular shade for your support). To ensure the success of the painting, it is advisable to do this work outside the winter period to ensure that the radiator is not hot.


Once the heater is dismantled, you can then proceed to clean it, firstly by dusting it off with a cloth or a brush if the radiator is too dirty.

To clean it a little more thoroughly, you can wipe it with clean water and a little dish soap using a microfibre cloth to remove any remaining dirt.

Do not hesitate to rinse it with clean water when cleaning is finished to remove any remaining dishwashing liquid.


The most important step in the preparation is to use a primer suitable for this type of surface, allowing the finishing paint to adhere but also being able to withstand the use of the radiator.

Ideally, you should choose a metal-specific undercoat that can withstand the heat from the radiator.


Applying the paint


Make sure your radiator is completely dry before applying the finishing paint.

To paint your radiator you will need a little equipment, namely a sash brush and a specific brush for radiators, which will allow you to apply the paint to hard-to-reach corners.

It is also possible to use a rabbit's foot for faster results, while being careful not to overspray. A paint gun can also be an option.


When it comes to application, it is advisable to apply the paint evenly and with regular movements to avoid drips or unevenness. This means not overloading the brush or rabbit's foot.


For optimal results, ensuring the paint finish, two coats of paint are recommended.


What color should I apply to my radiator?


It may seem trivial, but the choice of radiator color is still important.


As with wall surfaces, there are two schools of thought when it comes to choosing the colors to apply to your heating: firstly, the neutral and sophisticated colors that are part of the basics of the color chart.


The vast majority of people who want to repaint their radiator will therefore choose colors like white, which will bring in brightness (which will be the most popular color).

Black and anthracite gray are also increasingly used: bringing elegance, this color will allow your support to stand out and make it a decorative element in its own right.


The choice of colors is also linked to each person's personality, which is why there are no rules. Choosing the ideal shade should also be considered based on existing interior design, allowing you to create a harmonious color scheme between your walls and your heating system.
