I did several like banners and had to spray them with Krylon Metallic Gold before installing vinyl. Finish job and delivered product. Three weeks later, customer said paint was coming off in placing were it stuck to the other banner. Yes they were dry! Any help on why and how do I fix the problem? Can I spray the surface with something to prevent this from happening again?

Does the banner material have resonably strong "plastic-y" smell to it? If it does, plasticiser migration is very likely the cause of the problem you describe.
If you have this problem again, you might want to suggest that your supplier consider finding a better source for banner material...or consider finding a new supplier yourself.
Without having been informed or being offered additional savings, it is quite possible that you have started recieving cheaper and inferior "offshore" product...this seems to be a strong trend in the banner supply business...and I am speaking from experience, because it happened to us.
At the very least, ask your supplier who the mill is and get them to provide you with specifications. One key indications that you're dealing with offshore product is lousy "cold-crack" (ie. 20deg F). You should also ask for valid "flame certs" and test the flammability and self-extinguishing characteristics of the product yourself.

Hi Don;With my own experience i have found that putting paint over paint it takes a longer time to dry.It may feel like it's dry to the touch but undernieth it's still curing.this happens a lot in the fall and winter months.If by chance you used varsol to thin there is oil in it and this also will retard the drying time.Hope i made sence and helped.

I'm assuming you are talking about a vinyl banner. There is only one sure fire way to paint a vinyl banner, vinyl screen printing ink. Yes it's nasty, yes it stinks like hell but it is the only thing that will stick everytime. Tie Coat is risky, it doesn't always work ( they suggest doing a test first ) enamel receptive banners are risky ( you can always be sold something else ), nope, if I want to gamble, I'll go to the casino. I've had failures at one time or another with everything but the screen ink. Does no one make a gold banner material? If not offer an alternative. It's way to easy in this trade to get backed into a corner trying to appease a customer who wants something that just isn't available, ask me how I know

Did you wipe down the banners with cleaning solvent like rubbing alcohol before painting?
When having to ship signs or banners that really should have dried an additional day,, one of the old tricks of the trade was to put a light dusting of white pounce powder over the painted areas before shipping.
Enclose a note telling the customer they can remove this packing powder with a damp cloth.
I had one customer complain about paint coming off and sticking to the back of the banner but when they brought it in, it was obvious by the creases in it, that they had not only folded it up, but had set something on top of it after it was folded. DUH...
Always roll banners with graphics facing outward and never fold them. Store them loosely rolled, standing on end rather than laying flat.
