Zusammenfassung:PROBLEM TO BE SOLVED: To minimize the rebound amount of a spraying agent and the excessively sprayed amount of the spraying agent, which are industrial wastes, by making the spraying agent adhesive steadily onto a surface to be sprayed at the start and stop of spraying. SOLUTION: In the application of a spraying material containing at least a quick-hardening agent and a spraying agent, at the start of spraying, the starting order of feeding the spraying material from a spray nozzle is controlled so that the spraying agent may be discharged after or almost at the same time as the discharge of the quick-hardening agent, and at the stop of spraying, the stopping order of feeding the spraying material from the spraying nozzle is controlled so that feeding the quick-hardening agent may be stopped after or almost at the same time as the stop of feeding the spraying agent.
