Painting Aluminium wall Radiator

[Marty1966]

Hi
Can anyone suggest a paint preferably a spray paint for a wall radiator which is aluminium?
Also the process of priming if at all necessary?
Thanks

Degrease then rub down with emery paper to create a clean and smooth substrate ready for painting. Primer depends on the topcoat. Some paints like Hammerite don't require a primer but they aren't cheap. Hammerite smooth coat may be an option. I have rubbed down and reprimed my (steel) rads at home and top coated with gloss. Google hammerite as a starting point.

Many thanks for the info. Just trying to establish if aluminium needs to be treated differently ...

Nah not really....its more about the product you use...is it suitable for the application.
Many of the products on the market for this task will be ok. Just check if it requires a primer...many do. If you can post in here youll easy find a product for your rads on google..toolstation and screwfix and wickes will have them.

Bare aluminium benefits from using a self etching primer.

If your existing paint is sound most sprays should be ok.

Thanks Oops,
Its in perfect condition just need to change the colour really so perhaps priming isnt necessary

No priming required then. Clean the rad and use some webrax/scotchbrite pads to key the new paint.
