The weight of sprayings by spray gun is one of the most important factors on the workability of sprayings. In this paper, the suitable weight of sprayings by spray gun and many spray factors were examined experimentally and the equation of the weight of sprayings by spray gun was proposed theoritically. The following results were drawn from this study. 1) The maximum weight of sprayings is decided by the best efficent type in three jet types of spray gun. 2) The air pressure which produced the maximum weight of sprayings agrees with the most suitable spraying presure on many sprayings. 3) The flow quantity of compressed air increase with increasing the viscosity of sprayings. 4) The opening rate of nozzle does not influence on the weight of sprayings by spray gun, but influences on the corpuscle of sprayings which have effects on the texture of spray finishing. 5) The proposal equation by applying the jet theory agress, with the experimental value of the weight of sprayings by spraying gun.
