I want to take a mould from a decorative cornice and then reproduce in plaster to replace a damaged section. what moulding media should I use for the mould? baring in mind the cornice is in situ.
you can use latex dipping rubber for this. simply apply several layers with a brush after you first 3 layers have dried you can use a thixo latex agent to make a a batch with a more buttery consistency to speed up application. then you will need to make a hard supportive backing from plaster bandage to support the mould.
What would be the advantage of using this over fine casting plaster?
Herculite has a harder surface and is stronger than plaster, plaster can be quite soft on the surface and will wear down , chip and scratch easily if handled too much, Herculite is more resistant to this and has a harder surface.
