Prestia Normal Plus is a medium hardness plaster which is slower setting but harder than basic casting plasters. The slower set is popular for the casting of large objects and with its low expansion properties make it excellent for running moulds, either on the bench or in-situ.
Actually manufactured for use in the industrial ceramic industry, it is similar to Keramicast, but much slower setting.
