FIELD: construction.
SUBSTANCE: method to engobe concrete products includes grinding and sifting of kaolins or white-burning clay, powder supply into a plasma burner and plasma sputtering. Besides, previously they prepare a mechanical mixture of kaolins and white-burning clays with ceramic pigments and powder of dried liquid glass at the ratio of 10:1:2. Plasma sputtering is carried out at capacity of 5 kW and plasma-generating gas flow rate of 2.0 m3/hour.
EFFECT: reduced energy intensity, increased strength of adhesion and frost resistance of a coating.
