Prestia Casting Plaster is a premium, unformulated fine plaster of Paris quarried and calcined in the Paris region. Compliant with EN13279-1 Building Plasters Standard, it delivers a quick set time and exceptional results for decorative and fibrous moulding applications. Sourced directly and imported in volume, this plaster boasts a minimal carbon footprint. It can be recycled repeatedly without loss of quality. Our advice to users who would like a more viscous mix is to mix this plaster with another plaster such as Prestia Normal Plus Plaster for a less 'watery' blend suited to your specific application.
