Metal Paint
Protect and refresh railings, gates, garden furniture and radiators with metal paint from Hammerite, Rustins, Ronseal, Johnstone's and 151 Coatings. The range includes Hammerite metal paint in smooth and hammered styles, a direct to rust option, Ronseal Direct to Metal in several colours, rust remover gel and Rustins high heat paint.
For radiators, choose a white radiator paint or black radiator paint made for heated surfaces, and let the radiator cool fully before you start. Black metal paint and black Hammerite paint are popular on gates and fences, while white metal paint and white gloss paint suit window frames and pipework. A white matt paint gives a flat modern look on indoor metal.
Prepare first. Wire brush loose rust, wipe away dirt and grease, and sand glossy old paint. Rust remover gel helps on pitted areas before painting. Apply thin coats, brushing in one direction, and allow each coat to dry fully for the best protection.

How to choose metal paint
The right choice depends on the metal and how rusty it is.
| Option | Best for | Things to know |
|---|---|---|
| Direct to rust metal paint | Gates, railings and lightly rusted iron | Remove loose rust and flakes first |
| Hammered finish paint | Garden furniture and decorative metal | Textured finish hides surface imperfections |
| Smooth gloss metal paint | Railings and metal doors | Shows imperfections more than hammered |
| Metal primer | Bare steel, galvanised or aluminium | Use the right primer for non-ferrous metals |
| Radiator paint | Radiators and hot water pipes | Paint when the heating is off and cold |
Metal Paint: frequently asked questions
What is the best paint for radiators?
Use a paint labelled for radiators or heated metal, such as a radiator paint in white or black, and paint while the radiator is cold.
Can I paint over rust with Hammerite?
Hammerite Direct to Rust paints are made for application over rusty metal once loose flakes are brushed off. Check the tin for instructions.
Do I need to sand metal before painting?
Yes, a light sand or wire brush removes loose rust and gives the paint a key. Wipe clean afterwards.
What does high heat paint do?
High heat paint is made to withstand higher temperatures on items such as barbecues, stoves and exhaust parts. Always check the stated temperature rating.
How many coats of metal paint do I need?
Two thin coats are common for good coverage. Follow the drying times on the tin between coats.
