Painting Galvanized metal.

The paint is lifting in spots on some 30 year old galvanized metal.

Want to do a quick touch up, but not so quick the paint soon falls off.

Any tricks or sugeations on painting old but vert intact galvanized?


Rustoleum? Read lead? Zinc Chromate?

Either metal primer or Zinc chromate should do.

Id suggest starting by blasting it with a big (3500psi / 3.5~4.0 gpm) pressure washer with a 15 deg nozzle up close and personal.* That will remove anything that is loose or wanting to peel or flake soon.* I would follow that by scrubbing with TSP (trisodium phospate with some bleach added to remove or kill any algae growth.* Follow with etching*with a muriatic acid or metal prep solution, rinse, then zinc chromate primer.* Then finnish paint to suit.* It sounds like a lot of work but isn't to bad really,just a lot of steps.* I'm believer that it easier to do something well, than do it over,* JMO*

I like to use Pettit Rust Lock Primer or Pettit Trailer Coat on Galvanized steel. The stuff sticks like crazy. If you get it on you and let it dry, (it drys fast!) you will be wearing it for several days. I think the Rust Lock and Trailer primers are the same stuff. Just different labels.
