How to Paint a Galvanized Metal Door

Our front door is galvanized metal and the paint is popping off. What is the correct way to remove the old paint and repaint it? -Byrnes

Hi Byrnes,

If the door is peeling badly, you may need to use a stripper to remove all the paint. If only a few places are causing problems, you can probably get by scraping and lightly sanding the door to remove any loose or peeling paint.

Next, wipe down any bare metal with white vinegar to etch the surface and improve adhesion. You may also need to clean the door with a degreaser if the metal is oily as discussed in our article on How to Paint Galvanized Metal.

Next, prime any bare spots with a latex primer designed for use on galvanized metal, then topcoat the door with a high quality, exterior acrylic latex paint. Since darker colors absorb more heat, which can lead to peeling, you might want to stick with a lighter shade.

Good luck with your project,

Danny

  1. Hello Danny,
    I was browsing the internet to get some advice on how to repaint galvanized metal doors and windows and came across your article. I have had people working on the apertures over years but still I wasn’t satisfied with the result. Aluminium is taking over iron here on the Maltese Islands. I still want to keep mine and that is why I am ing you regarding these apertures. If it is not to much problem I intend of having a go myself and need some good advice please.

  2. I want to paint the house flashing at the roof edges and the soffits under the roof edge. Also would like to paint the metal garage doors. I want to spray paint, as this would require a lot of masking off I really need to do this right.
    Thank you for any advice,

  3. I had to finish peeling off the vinyl from my mobile home front door and now I’m painting it. I was on the last coat and scraped a bubble with my fingernail and the entire area started peeling. The paint “expert” at Lowes said I wouldn’t need to prime because the Sherwin Williams line of paint I bought had primer in it. What do I do now?? I’m also planning on painting my shutters.

  4. Do I just wipe soffit and flashing with white vinegar? How long do I wait? The flashing with Behr oil base semi gloss enamel? Dark brown.

  5. Hello Danny,

    • Hi, Dr Aye,
      A common paint stripper raises concerns (as seen here: https://www.cbsnews.com/news/dangerous-paint-stripper-chemical-methylene-chloride-ban-on-hold/); instead, try a safer alternative, such as CitriStrip.
      Thanks for your question!
