In spraying work, the speed of the gun's movement has a great influence on the coating effect.
1, If the manual spray gun moves too fast, the surface coating is thin, appears to be lean, poor leveling, coarse;
2, If the manual spray gun move slowly, the surface of the coating film is certainly very later, and easy to produce the phenomenon of hanging.
3, The most ideal speed of the spray gun movement is after the end of spraying, the surface coating of the coating is full, uniform, wetting. This requires some spraying experience in the operator to control.
