FIELD: technological processes.
SUBSTANCE: invention is related to the field of construction materials. Gypsum board contains at least one layer of facing paper that creates outer side of board and priming emulsion applied on facing paper. Priming emulsion contains plastic pigments as bleach, preferably in amount from 5 to 40 wt % of plastic pigments. Emulsion is applied in amount from 10 g/m2 to 45 g/m2.
