FIELD: application of protective coats on roofs, buildings, walls, pedestrian ways for forming friction surfaces. SUBSTANCE: proposed unit has working member connected to rigid adapter for forming convergent jet of surface, mobile bogie with ejector and feeder bin carried on it, device for feeding liquid resin to working member, compressor and electric generator located away from bogie. Besides that, proposed device is provided with unit for transportation of material to ejector and additional devices for transportation of liquid resin to working member. Mobile bogies also carries pump and proportioners connected with electric generator. Device is additionally provided with container for building-up excessive pressure of liquid resin before delivery to working member. Rigid adapter may be held by operator; it is provided with starter for switching on/off compressor and pump. Switch connected to rigid adapter is used for switching-on pump and ejector. EFFECT: enhanced strength of coats. 4 cl, 3 dwg
