Can anyone tell me best way to paint a galvanized steel flag pole. There must be a good primer that someone can recommend.
Any of the big stores should have galvanized primer.
Steve, anything with zinc-chromate in it, the more the gooder, enamel base. Scuff the pole lightly with 180 grit and clean thoroughly. Always use a zinc when painting galvanize or stainless steel because they are non-pores.
Use ZRC Cold Galvanizing and you are done.
wipe down with muratic acid. this will give a surface finish for the paint to bite onto. common practice.
I have used a product called Rust Grip. It's expensive as all hell but two coats of it and your're done. Can't spray it. It rolls on beautifully and dries fast to a silver finish. You tube it. I've used maybe 5 gallons of it in painting rusty areas on my cranes where I don't dare risk sandblasting. It will definitely adhere to galvanizing.
I've always heard you must wash it in vinegar before you paint over galvanized metal.
I want to paint it hunter green, so I think it needs a primer first. I just don't want to waste money and have it peel in a few years.
Rustoluem makes primer for aluminum and galvanized metal.
It is actually latex but can be top coated with oil based paint per the can.
I've used it on galvanized gutters and downspouts, galvanized furnace flues and aluminum roof vents followed by oil base top coats.
It works very well here in our MInnesota climate. It shrinks right up and makes a tight bond.
Rustoluem used to make oil based primer for galvanized metal - very strong stuff that would make your nostril hairs fall out. I wish it were still available.
Does anyone know where I could buy a gallon of Rust Grip to try? I found lots of websites with data but no retailers.
