Hi, I have an old corrugated gavanised iron roof that has been previously painted with an Alkyd gloss primer/finish coat, it needs repainting, what would you recommend. Thanks Keith
Assuming the previously painted roof is clean, dry, sound and prepared as detailed in the technical data sheet we can recommned Rust-Oleum Mathys Noxyde Pegarust.
We would recommend testing for compatibility and adhesion on any previously applied paints.
The life span of the paint could be effected by the adhesion of the previous paint coating.
