FIELD: technological processes.

SUBSTANCE: invention is related to device for application of material. Device comprises nozzle (1) with internal channel (100), having inlet end (102), in which soaked material is introduced, and outlet end (103), from which material is sprayed. Internal tubular element contains single through opening and multiple through slots arranged along circumference. External channel (200) is installed around internal channel (100) and is communicated with it, and has inlet end (202) for introduction of gas in it, which is passed through external channel and pushes out soaked material flowing in internal channel. According to the second version, device comprises hose (20) for material supply. Through water inlet (10) communicated with hose (20) for material supply, water is supplied for material soaking. Inlet nozzle connects hollow flange (40) with inlet end of external tubular element. By means of nozzle (1) soaked material is taken out. Mixing chamber (30) is installed in intermediate position and is communicated with hose (20) for material supply and comprises at least one inlet (90) for introduction of mixing gas.

EFFECT: provides for higher extent of gunned material adhesion, improved quality and durability of applied lining.
