Preparing Plaster Moulds for Casting with Shellac (Don’t Skip This Step)
Preparing plaster moulds correctly is a critical step before casting can begin.
In this video, Andy demonstrates how shellac is used when preparing plaster moulds (molds) for casting. He shows how shellac is mixed and applied, and how it seals the surface of the mould so it can be used for repeated casts without damaging the detail.
This video focuses specifically on how shellac is used in plastering, within the context of plaster mould (mold) preparation and casting. While shellac has many uses beyond plasterwork, here it is shown as a traditional method used in plaster workshops when preparing moulds for casting decorative elements.
