This morning I'm working in Inverness, IL for a wonderful client. I applied the initial coat of RS-100 to all underground ductwork. This specialized coating serves as a protective barrier, safeguarding the ducts against corrosion and extending their lifespan. The application process involved thorough cleaning of the duct surfaces before evenly applying the RS-100 coating. This proactive measure ensures the durability and efficiency of the underground duct system for years to come.
