FIELD: construction.
SUBSTANCE: method for production of moisture-resistant product on the basis of gypsum includes mixing of siloxane emulsion with water for tempering, used for production of specified product on the basis of gypsum, mixing of small amount of fast roasted magnesium oxide with roasted gypsum, mixing of specified mixture siloxane emulsion/water for tempering with specified mixture roasted gypsum/magnesium oxide for production of aqueous suspension and formation of specified suspension with the possibility for formed suspension to harden in order to produce moisture-resistant product on the basis of hardened gypsum. Invention is also related to method for addition of siloxane with production of moisture-resistant product on the basis of gypsum, to moistureproof gypsum board. Invention is developed in dependent claims of invention formula.
EFFECT: improved water-repellent properties of products on the basis of gypsum.
