Milo demonstrates how you can use the duoMatrix NEO polymer-modified gypsum system, thickener, accelerator, and chopped fiber to create mold support shells (or "mother molds").

duoMatrix NEO and Chopped Glass Fibers can be used as a low-cost alternative to support shells made from urethane resin, epoxy, or fiberglass. Unlike using plaster alone, this method will produce durable, impact-resistant lightweight support shells. The use of Matrix Thickener allows you to use duoMatrix NEO to build a support shell even on a tall 3-Dimensional mold, as it will hold a vertical surface with minimal slumping.
