Our front door it in need of some TLC. It looks very much like it's been painted dark grey then painted white again as there's some peeling around the window sections. I want to do it in a sage green/duck egg blue/muted F&B type colour but imnot sure which type of paint it needed and how to prep (aside from a quick sand over). The house is a new build and door seems to be metal fronted. Any ideas?
