Having just added on to a galvanized metal building, the new metal is a real
contrast to the existing structure. Anyone know of an environmentally safe
wash, that can be used to age the new galvanized metal for at least a little
If not, any ideas on how to best prep the new and old metal for paint?
Thats what aging is all about. The appearance is never regular, and it does
have rust spots etc.
I did an art project for an artist, and we used old tin to build a barn.
1860 vintage prairie barn. I have pics of it and it came out nice. We put
a roof on the building with "new plastic roofing" (greenhouse type) and then
covered it with the old rusty tin characteristic of praire barns in that
vintage. So in this case it was to make it look old.......
It's difficult to paint galvanised metal. Last time I tried it was like
trying to paint a wax candle with water based paint. I tried to degrease it
with different things but nothing worked.
Perhaps different things on some scraps...
Says it must weather for 6 months before painting...
You can try salt water or hydrogen peroxide. If you are going to paint
the galvanized metal it needs to be "etched" with a product that tin
benders use to put on the metal before it gets painted. Vinegar might
do the same thing. Experiment.
Thanks for ALL the suggestions guys. I really appreciate it.
I have picked up a couple of Klean Strip products, Tri-sodium Phosphate
Substitute and Phosphoric Prep & Etch. I plan to experiment with these and
vinegar, hydrogen peroxide, and salt water as well. If anyone thinks of
anything else, let me know. I'll be back in a week or so to let you know how
