Abstract:
1. A system for applying barrier coating leak sealant to interior walls of piping systems in buildings, comprising: a dryer for drying pipe interior walls of a piping section in a building; a cleaner for cleaning the dried interior walls of the building piping section without using liquids and chemical agents; an applicator for applying a liquid barrier coating leak sealant with a selected viscosity to the cleaned walls of the building piping section; a compressed air generator for generating positive compressed air inside the building piping section for drying and cleaning and applying the barrier coating leak sealant into an end of the building piping section, wherein the compressed air generator maintains a positive pressure above ambient throughout the building piping section until the leak sealant has become set; and a collector for generating a vacuum connected to a second end of the building piping section, wherein the compressed air generator and the vacuum generator are operating simultaneously with each other while the cleaner is cleaning the interior walls of the building piping section.
