Question: will acrylic paint stick to polystyrene?
Answer: Water based paints or acrylic craft paints are the best to use on Styrofoam. Water based paints, specifically poster paints, work well with younger kids as they can get a really good and thick coverage of paint on the polystyrene shape. ... If you do use metallic paints, a cool melt glue will stick buttons, jewels etc.
