Spraying plastic hard coat onto foam props
EPS foam is a great material. Light weight, not too expensive & relatively safe to work with. Its only flaw is it’s fragility. We spray a strong 2 part plastic coating on our props. Then we finish the look with automotive paints. Using materials that are industry proven means our sculptures last indoors and outside in the elements. The prop I’m coating in the photo was designed for children to climb on.
