FIELD: manufacture of gypsum decorative products. SUBSTANCE: method consists in preparation of a gypsum mix (1 part of water and 2.2-2.5 parts gypsum), placement of the mix in a form at a vibration frequency of the vibrating table of 250-500 vibrations per minute, uniform vibrating tamping during 15-35 s, disengagement of the vibrating table, pressing-in of the product by the pressing plane, curing of the product up to the complete hardening, dismantling of the forms, drying at a natural plenum-exhaust ventilation during 5-6 h and treatment of the product by a water-repellent compound with a subsequent panting. The form ash a mould made with fields projecting from the form boards around the edges. Each inner side of the form board is chamfered with formation of a gap between the mould and the form boards, 0.5-1 mm wide, and the upper inner edge of the board is chamfered at an angle of 10-15 deg. For casting of the mould use is made of an adhesive solution and a dry mix of gypsum and cement. EFFECT: enhanced quality of gypsum products with a relief pattern. 6 cl, 2 dwg
