A high quality plaster from the Prestia Siniat range, Prestia Creation has proved itself to be an excellent, hard and easy-to-use material. As with all the Prestia plasters, its low expansion rate is very valuable especially when running under zinc templates. It is popular in high spec GRG castings, either used with fibreglass chopped strands or CFM Unifilo fiberglass mat.
It is regularly added in small amounts when mixing to basic casting plasters, such as Prestia Casting to give the casting plaster a bit more hardness. It is comparative to Herculite 2 although not quite so hard and is slower setting.
