The good news is that metal siding is one of the best surfaces to repaint. The process of repainting pre-finished metal siding is a little different than it is for other types of exterior surfaces.

How do you prep metal cladding for painting?

Prep and prime

Remove any dirt, rust, grease or other contaminants from the cladding and apply a high-tech, quick-drying primer such as RUST-OLEUM Mathys Primer. This step will prevent further oxidation of weathered cladding and protect new bare cladding from corrosion.

What paint do you use on cladding?

Zinsser AllCoat Exterior is a high performance coating that is suitable for exterior protection for wood, metal, masonry, plastic, concrete and cladding. No primer is needed, and it can even be applied to unsanded surfaces and glossy paints.
