GRG is primarily composed of two raw materials: high density alpha-based gypsum and glass fiber reinforcement. The gypsum plaster should be neutral or of low alkalinity to ensure its compatibility with E” glass fiber. Additives commonly used within the plaster industry are acceptable provided they are used in accordance with the gypsum manufacturer’s recommendations.


GRG is for use where it is not subject to dampness. (Do not use where it is openly exposed to rain or for fountains, pools or wet locations. For these applications see GRP). GRG can be used whenever a light, strong and fire retardant material is required (casinos, hotels, theatres, residential, etc.)
