I have painted some sheets of wood with standard acrylic paint (which has then dried). I have found that when I stack the sheets against each other the painted surfaces stick to one another after a day or so (to the point that when they are separated they will tear the paint from one of the pieces of wood).
I was wondering if there was a way around this? Do I need to treat the paint in some way? Or will all acrylics do this (I have had this problem with several acrylic paints).
