GMB-2,5 model plaster, white

GMB-2,5 white model plaster is a modified mineral sealant with enhanced durability manufactured from gypsum roasted from natural high-quality gypsum from the deposits of NOWY LĄD mine. It is used mainly in model making, making gypsum moulds, sculpting and coving. Low expansion of the gypsum enables an accurate representation of shapes of coving patterns.
