A1, the abbreviation for Acrylic One, is a two-component material consisting of a mineral powder and a water based acrylic resin. These bind in such a way that a strong material is created. A1’s potential use is wide-ranging and could effectively replace much GRG, GRC and GRP in many of the situations where those materials are now used.
