Produced from top-grade calcined gypsum and mined in the Paris area, Prestia Casting Plaster is an unformulated fine plaster of Paris. Adhering to EN13279-1 Building Plasters Standard, this product provides a quick set time and is ideal for decorative and fibrous moulding work.

This is true Plaster of Paris, as it is quarried and calcined in the Paris area.  Imported directly by ourselves in volume, its carbon footprint could hardly be lower, and if disposed of correctly it is recyclable - the waste stream is used in the manufacture of plasterboard, for instance, and as gypsum it is one of the few materials in the world that can be recycled again with no discernible degradation to the final product.

Prestia Casting plaster must be stored in its original shrink-wrapped pallets, or single bags must be stored avoiding direct contact with the ground, and protected from water/moisture contamination.  It is recommended to use the product within 6 months from the date of manufacture printed on each bag.
