Radiators heat up and cool down repeatedly. That constant change in temperature puts stress on paint films, especially on bare metal.
Radiator paint is specially formulated to:
-
Adhere properly to metal, including previously painted surfaces.
-
Create a smooth finish that stays intact as the radiator heats and cools.
-
Protect the surface from wear, making it easier to clean once fully dry.
Using the right heat-resistant radiator paint helps you achieve the best results and avoid the need for repainting sooner than expected.
We stock an extensive range of paints that are suitable for radiators, covering trade formulas and designer finishes that perform reliably on metal.
Self-priming Paints for Radiators
Self-priming radiator paints are widely used for painting radiators because they combine heat tolerance with efficient adhesion across challenging surfaces. These paints help you save time and reduce costs by serving as a primer and topcoat in one.
You can select from water-based or solvent-based variants across various finishes, including satin, gloss and matt. Some of our most popular self-priming products for radiators include:
-
Zinsser Allcoat Exterior Water-Based:Â Recoatable in just one hour, this mould-resistant paint bonds well to metal and various other surfaces. With an expected lifespan of up to 15 years, this paint is a reliable choice for long-term performance.
-
Zinsser Allcoat Interior Solvent-Based:Â This quick-drying paint is designed for efficient refurbishment work, including spray paint application. As a 4-in-1 solution, this product primes, seals, blocks stains and creates a lasting finish. This makes it perfect for budget or time-sensitive projects without needing to sacrifice performance.
Water-Based Paint for Radiators
Our water-based trade finishes are frequently chosen for painting radiators because they balance performance with quicker drying times. Some of our popular choices include:
-
Johnstone’s Trade Aqua Guard Durable Gloss: This high gloss finish uses surface protection technology to help the paint resist knocks and marks on interior metal.
-
Benjamin Moore Interior Matt:Â This acrylic, low-VOC paint provides dependable coverage on suitably primed interior metal.

If you need additional advice, read our guide on how to paint a radiator. We always recommend painting radiators when they are fully cooled. Allow at least 24 hours of drying time for the best results.
The best paint to use is a high-quality satin paint. Zinsser Allcoat Exterior Satin in Anthracite Grey is a popular choice for large commercial projects where consistency is key. Highly resistant to cracking, flaking and blistering, this trade paint has a great subtle-sheen finish and is suited to constant changes in temperature.Â
The easiest way to paint behind a radiator without removing it is by using a long-reach radiator brush. This avoids issues with having to try to remove a radiator from a wall, as you can paint all the hard-to-reach areas. Alternatively, you could colour-match your radiator to the colour of the wall behind your radiator, as this is becoming a popular trend.
