PURPOSE: To provide a spray gun which sprays a resin and catalyst carried through respectively separate routes by air pressure while mixing both. CONSTITUTION: The pneumatic spray gun 10 has a mixing member 14 and a valve rotor 36 has a valve 18 for the resin and valve 20 for the catalyst formed by valve passages 44 (46). The valve for the resin is opened just before the valve for the catalyst is opened by controlling the turning of the valve rotor 36 with a pneumatic trigger part 24 and a sliding member 28. This liquid mixture flows into a mixer 22 after the catalyst is distributed into the resin by a distribution plate.
