When does acrylic paint have a long shelf life?
Good to know....i appreciate your time. Acrylic paint has a pretty long shelf life if it is tightly closed. You will know if it's "gone bad" by either it's lack of "flow" (it's gotten hard or too gooey caused by air - it's drying out) or it smells bad. Acrylic paint does "sour" or "mildew" if it is left "wet" too long. Spring cleaning! Good idea!
