Methods and process steps for cleaning and providing barrier coatings to interior walls of piping systems. An entire piping system can be cleaned in one single pass by dry particulates forced by air and the piping system coated in one single pass. Pipes can be protected from water corrosion, erosion and electrolysis. Pipes having diameters of approximately⅜″up to approximately 6″are treatable. Piping systems such as potable water lines, natural gas lines, HVAC, drains, and fire sprinkler systems in homes. apartments, high-rise hotel/resorts. office towers, high-rise apartment and condominiums and schools, can be treated. The coating forms an approximately 4 mils or greater covering inside the pipes. Buildings can return to service within approximately 24 to approximately 96 hours.
