FIELD: process engineering.
SUBSTANCE: invention may be used for application of protective-decorative coatings on porous materials. Coat discontinuity is eliminated and its adhesion to fibrocement article is increased by using powder coating based on polyether dye. Said dye is applied pneumoelectric spraying at 15-30°C and humidity of not over 80% while polymerisation is carried out at 130-155°C.
EFFECT: ruled out coat discontinuity.
