How to Repair Peeling Paint on Metal Door

  • Transcript

    LESLIE: Mark in North Carolina is having some issues with door paint. Tell us what’s going on.

    MARK: I’ve got a metal door. It faces east. The sun rises on it. It’s a solid-white steel door but it’s got a solid-glass storm door in front of it. And I have painted it for the last 19 years and the paint peels off. Looks like Shirley Temple’s curls.

    TOM: So here’s what happens. When you keep putting paint upon paint upon paint, eventually those layers just delaminate and they will not stick. So, what you have to do, at this point, is pull that door off and strip it all the way down to the metal. You need to get all that old paint off.

    Once all that old paint is off, you sand it very lightly. And then I want you to use an oil-based primer, like a Rust-Oleum. Paint it on, let it dry. And once it’s good and solid, then you can put one or two coats of topcoat over that.

    But I think you’re putting good paint over bad paint and it’s just finding a new layer and separating. And you’re right: when you have those storm doors on, it does add to the stress of that finish. But I think if you strip down all that old paint, get it back down to the metal, sand it up, put a primer on it and a couple of coats of finish paint over that, I think it’ll stick that time, Mark.

    LESLIE: Alright. Thanks so much for calling The Money Pit.
