A method of proactively protecting property and buildings constructed thereon from wild fire by spraying environmentally-clean anti-fire (AF) chemical liquid prior to the arrival of wild fires. Intelligence data is remotely collected relating to risks of wild fires in specified regions, and maintained in a network database, and used to generate anti-fire (AF) spray protection maps and task reports for execution in the specified region. Prior to the arrival of a wild fire to the region, and based on the GPS-specified anti-fire (AF) spray protection maps and task reports, application servers deployed on a wireless system network issue a request or order to the property owner, or its registered contractor, to apply clean AF chemical liquid spray on the GPS-specified parcel of property using a GPS-specified AF chemical liquid spraying system, so as to proactively protect the property prior to presence of wild fire.
