I have a design in mind for some shelves using black gas pipe & fittings
as the frame (basically the pipe with floor flanges attached to wooden
shelves). I'd like to paint them a gloss white. Anyone know if this
stuff will accept paint w/o a major PITA prep? Alternatively, I could
go with the galvanized, a bit more $$$ but not enough to worry about.
I'm guessing though the galvanized would be even harder to get paint to
Denatured alcohol or electronic grade isopropyl (not rubbing alcohol) or
methanol. I clean just about everything metal with alcohol before painting.
If there is a lot of oil, water and soap first will get most of it, then
rinse with alcohol and dry immediately with a torch to prevent rust.
Paint will stick to galvanized just fine, the surface will be more textured
though. A primer with either kind of pipe wouldn't hurt. Galvanized will
still give superior rust resistance even compared to painted black pipe.
A can of spray paint and a tarp should be all you need for setup
Thanks for the great reply. Denatured alcohol it is. I don't know
why I was thinking paint wouldn't stick to galvanized. If anything, the
slightly "pebbly" surface would be a good look with the gloss white.
believe it or not, these are going in the living room ;-0
Vinegar should not etch galvinized steel but in and of itself would also be
a reasonable cleaner for cutting oil (it is used in many window cleaners).
It would also help remove scale if you dared to use used pipe.
Primer will give it plenty of tooth.
BTW Have you seen cold galvinizing spray. It is basically zinc spraypaint
and can be used as a primer directly on steel.
Vinegar is a mild acid so I suppose that is why. It probably also acts
as a cleaner. I saw that tip way back in the ice ages and have used it
several times. Always got a good job without primer. Does it work? I
don't know if it does give 'tooth' but I haven't had any failures doing
