I painted some small canvas' last year using acrylic paints, Golden Heavy Body to be specific. They were left to dry, or so I thought. Here it is a year later and if I lean one painting against another it pops the paint off of the bottom painting when I seperate them. The paint is in very thin layers and not diluted. In talking with a friend we both thought that this was odd as I've never had this problem in the past.
Suggestions as to what may be going on?
