FIELD: coatings for products from gypsocard and their manufacture.
SUBSTANCE: the gypsocard with a coating applied onto it has: a gypsum core having the first side, second side and an outer sheet positioned on the first side, and a coating applied at least onto part of the external sheet, at least part of the coating penetrates at least through part of the external sheet to the gypsum core. The method for production of gypsocard with a coating includes: application of a gypsum suspension with production of damp gypsocard, having a gypsum core, application of coating onto the outer sheet of damp gypsocard and subsequent drying of the damp gypsocard, at least part of the coating penetrates at least through part of the outer sheet to the gypsum core. The method of wall production includes production of gypsocard with a coating in compliance with the mentioned for application of coating onto damp gypsocard, fastening of gypsocard with a coating on a supporting structure with production of a wall and application of adhesive tape and finishing of the joints between the adjoining sheets of gypsocard with coating with the use of a fastening agent, whose composition is essentially similar to the coating composition. The invention is developed in the species claims of the invention.
EFFECT: accelerated mounting and production of more durable finishing coatings, improved finished appearance of the finishing coating and reduced duration of production and reduced cost of it.
