How To Reproduce a 3D Sculpture Using Brush‑On™ 40 Mold Rubber

Matrix® NEO® is a polymer modifed gypsum that is easy to use and cures to a tough, hard plaster. It is mixed 2 Parts A to 1 Part B by volume. The goal in making this casting is to make it hollow and lightweight.

Pour the NEO® into the mold cavity and rotate the mold to allow the NEO to build up against the mold walls. Mix and pour additional batches of NEO® into the mold. Continue to rotate the mold allowing the batches of NEO to build in layers on itself. After the final batch of NEO® is mixed and rotationally cast into the mold, allow all layers to cure for at least an hour. Remove the mold straps from the mother mold.
