Any paint job is only as good as the prep work. Jim is correct that it will need a light sanding. However, you should clean the surface before painting as there may be oils or other substances on it that will cause paint to fail to adhere. I'd use denatured alcohol then sand with 240 grit sandpaper. I don't know how good you want this bed frame to look but in most cases, after sanding then cleaning off the dust, it will look just fine if you shoot it with several light coats of white Rustoleum - emphasis on several light coats. The mistake amateurs usually make is they just hose it down and get all kinds of nasty runs and drips.
You could get fancy, priming it with a sandable primer, sanding the primer with a finer grit like 600 then applying a glossy color coat and it will look as shiny as a new car.
If you're going from black to white, you would need a couple of coats at least. So be patient.
agreed but sand hard-paintbrush might be handier-no overspray,any paint will work indoors,dont have to buy metal paint
no just lightly sand it and get spray paint you can us on metal
Hi I am interested in painting my dark, metal bed frame white. All the furniture in my room is white and so is my headboard. I'm talking about the part that the box spring sits inside of, just the bottom part with the legs and wheels on it. How would I go about painting it? Since it is steel or some variety of metal anyway would it require special treating?
