FIELD: finishing building materials, used for evening out facade surfaces of buildings and surfaces inside rooms.
SUBSTANCE: in the method for producing knifing filler, siliceous binding substance is prepared by grinding sand in ball mill with addition of alkaline admixture. Grinding of sand is performed by quartzitic pebbles at moisture level of 14-30% and temperature of 20-80°C. Then stabilization of siliceous binding substance is performed for at least 12 hours, and then siliceous binding substance is mixed with, successively, dispersion of acryl and sodium formate with following ratio of components, %: siliceous binding substance 90-94, acryl dispersion 5-8, sodium formate 1-2.
EFFECT: increased hardness of finishing materials, amplified stability thereof to effect of environment, many times decreased amount of components and improved ecological properties thereof.
