Moldmaking and casting: Hydrocal Plaster Mother Mold Process

This is a basic mothermold support shell for a silicone rubber mold made using white hydrocal reinforced with fiberglass matte. This is a good method for creating thin, lightweight, and durable support shells. When using this method over a brush-on urethane mold make sure a release of wax is applied to the rubber surface. For more information on the skin technique check out our DVD.

Have you ever dropped a hard mother mold and had it shatter on the floor, forcing you to do it over again? That would seriously bite...

[brickintheyard]

@KewneRain That's why we add the fiberglass matte!
