How Do You Make A Fiberglass Molding?
Molding fiberglass is a complex process, but is not impossible to do at home. The molding and casting process for fiberglass is similar to most other types, with some alterations for safety, since the laminating resin used in casting is highly toxic. The best way to mold fiberglass is through a two-part plaster mold, which is strong enough to hold any shape and is designed to allow the hard fiberglass to easily separate from the mold. Coat your model, usually a finished sculpture or existing non-porous object, in a mold release agent. If your model is a soft clay sculpture, either bake the sculpture or coat it in Krylon Crystal clear, if you do not wish to save the model. Along the middle line of the model, build up a wall of modeling clay from one side of the base to the other. Make sure that the modeling clay wall is at least as tall as you would like your mold to be. Mix together gypsum and water in a bucket to create a smooth plaster mixture, and apply an impression coat to one sid
