If you can easily peel your new paint off with your fingernail (likely), then as others have said, you may have to strip it off and start again. But if you are getting some decent adhesion (unlikely), i would try to rectify what you have presently.
Either way I would give it a few days to dry out and harden up a little, then do a test on a small area. If you are getting some decent adhesion, lightly but thoroughly sand with fine sandpaper or sanding sponge -- apply a tinted latex bonding primer and let that dry for a day or two. Then try one coat of your finish on top of the primer and let it dry for a day. If there is no separation of the film and you are continuing to get adhesion, then you are good to proceed.
If you are forced to strip off your coatings I would do a much more thorough sand on the original paint and then apply your primer. With problematic surfaces like this it definitely pays to test to see what works in small areas before hitting the whole job.
