Mold Making and Casting: Casting R2 Rigid Foam



Here are 2 methods for achieving a good matte, paintable surface on rigid, urethane foam. Both baby-powder and primer (sprayed into the mold and allowed to dry) may be used to create a cast part with a matte surface for easy painting. New Prime-it primer may also be used to simplify the painting process.
