Painting galvanized corrugated metal?

[bar2hunter]

Working on light weight blind, skinned out with galvanized corrugated roofing metal. I'm wanting to paint the inside flat black. I was shopping paints today and ran across paints (i.e..Rustoleum) that specified not to apply to galvanized.

So, my question is...any of you folks painted galvanized corrugated metals and what stuck for ya?

I've painted small areas before but I don't remember what kind of paint it was. I know it was a can of spray paint and I made sure I cleaned all of the oils off of it before I painted it. Hope that helps a little.

Galvanized metal is galvanized because it's been coated with a zinc coating. They make special primers for it but they can get pretty expensive. These are usually industrial coatings and are not really designed for the retail user. I worked for Sherwin Williams for almost 7 years and can attest to the training their sales guys go through. So with that I'd say 'Ask Sherwin Williams'. Otherwise...visit their website...

Galvanized metals should be coated with an etching primer but as already indicated it can be pricey. A cheaper alternative would be to let the material weather to a dull battleship gray. For your purposes the paint should be fine since you shouldn't need too much abrasive resistance. The paint is going to stick no matter what as long as the oils from the corrugating process are removed. I'd just weather it down a little.

Try using vinager on it before you paint. I have heard it's used to make galvanized buckets look old and dull. It should be enough to get the paint to stick for what you want.

Sand blast it, problem solved and paint it however you like

AHHHH...I wasn't thinking about the "weathered" part. The stuff I'm using is pretty weathered...almost too weathered (almost rusted through) in some places. From that aspect, I think adhesion should be no problem.
Thanks for the input!!!

BTW...Here's the blind I'm building. Specs are 5'W X 6'L, 5'6" rear height X 6" front height, framed out of 1" square tubing, vert windows are approx 9" X 18", ....

(Sorry for the poor quality pics!)

Good job on building the frame. Paint should stick to to that metal as it has been weathered.

We have wiped galvanized stuff down with vinegar and paint has stuck to it well.

IT has already been said but vinegar is the key here, I have done this in the past on feeders and other galvanized items and it works well..... I filled a pump up sprayer with the vinegar and sprayed it on pretty thick, let it dry good, wipe it down and spray on the paint.... I have a sweeney feeder that is still holding paint I put on about 6 years ago and it has been in the woods the whole time!!!!

You can etch the galv. with bleach or vinegar. Spray or brush on a product called Ospho, you can get it at hardware stores, it kills the rust and gives it a primer at the same time. The Ospho is a little expensive, but it works great.

Dang I was about to say I had no idea but that would not stop me from putting in my 2 cents. My Daddy always said use vinegar first too.

Use the ospho it will etch the galvanize and stop the rust.

Follow the diredtions

Thanks folks! Didn't even think of Ospho...I've got some handy. If/when I run outta that, I'll go to the vinegar (NOSE PLUGS!)

While we're on the subject, how much coverage do y'all think a can of the rubberized fender well coating will get? I know that may be a more expensive route but the limited experience I have has shown me that it has good adhesion and probably makes for a better noise dampener.

Bumpin the question..."how much coverage do y'all think a can of the rubberized fender well coating will get?"
