FIELD: process engineering.
SUBSTANCE: invention relates to antirust protection of metal, concrete and other surfaces by metal-filled paintwork materials. In applying dense conductive zinc layer on the surface, fine zinc powder is mixed with paint directly behind sprayer nozzle. To allow high homogeneity of paint mix and formation of dense uniform zinc layer of the surface, prior to mixing with paint zinc particles get static electric charge for uniform distribution with paint flow drops produced by spraying. Mixing is performed in jet flowing from nozzle to surface being coated.
EFFECT: simplified process, possibility to use common industrial painting equipment.
