I have a customer that wants some real estate signs done and wants a gray background. What proceedure do you use to paint aluminum? In the past I have just used a scratch pad, cleaned and painted with a spray can. Apparently the thinner in the spray can is to hot and I would get a reaction, lift and "curtling."
Thanks for your help

i'd order them from a place like grimco...if you have more than 12...other wise if it were like a 18 x 24 i may cover in gray vinyl if there weren't too many.
i've always been able to roll one shot on aluminum after i go over with a scotch pad.

Hi Rob, Aluminium MUST be etch primed before painting,the etch primer is available at most paint stockists and come in a grey colour, so I would de- grease the aluminium, etch prime,undercoat and gloss as normal.There is no short cuts in this process if you want the paint to stick correctly.

I usually just scuff with a pad first, prime with Ronan Block-out White, then roll on the enamel color. This gives the enamel something to "grab" onto...

yeh....it's too much trouble to deal with unfinished aluminum when for less than the cost of all that cleanin' an' primin' you can get it with a baked-on finish that only needs scuffin' an' rollin'. On small jobs tho', if I've only got just a few...mabey less than 10, I use a "Preval" airless sprayer if I need to custom mix any colour, an' use anything from Oneshot to automotive paints, an' even do fades without draggin' out the compressor an' all...

Use pre-painted aluminum. Raw aluminum needs to be etched, have a conversion coating, then primed and painted--whey! Pre-painted aluminum which is probably more readily available just needs to be scuffed with scotch-brite. I use the red pads, available from auto supply stores. Then clean off the dust with rubbing alcohol (kills static) and roll on 1 Shot.
