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 better match?
If not, any ideas on how to best prep the new and old metal for paint?
I thought of that too but wouldn't that leave it splotchy? I can't see how you could get if even.
..and then paint it quick or it will rust.
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...
Painting won't last. Use a deglosser on it and leave it alone.
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.
painting...
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 they worked.
Yogurt perhaps? Used for matching new and old roof tiles. Gets the bugs going..
That's an unusual angle. Grow microbes!
