PURPOSE:To continuously spray paint over a wide range in the optimum mixing state, in the painting of quick-drying paint, by respectively sending liquid paint and a curing agent under pressure by separate reciprocating pumps each adjustable in the number of reciprocating rotations thereof. CONSTITUTION:Paint is sent to an injection device 2 from a paint tank 27 through a transport pipe 3 by the variable paint pump 10 driven by a motor 11 while a curing promoter and the like are respectively sent to said injection device 2 from tanks 28, 29 through motors 6, 7 and variable pumps 8, 9 and introduced into the pipe provided outside the paint transport pipe 3 in said injection device 2 to be injected in the flow of the paint from the emitting nozzle formed to the outer peripheral surface of the transport pipe 3 and mixed with said paint. When the resulting liquid mixture is injected toward the surface of a structure 1, air is appropriately sucked in the jet stream of said liquid mixture to make it possible to diffuse the paint.
