Foster 40-20 Antimicrobial Coating for HVAC Duct and Surface Mold Control

Foster 40-20 is a white, EPA-registered fungicidal coating supplied in a 5 Gallon container. It prevents mold regrowth and the spread of odor-causing bacteria on walls, ceilings, pipes and HVAC duct systems.

Foster 40-20 Coverage and Use

  • EPA-registered fungicidal formula — carries the federal registration duct cleaners need to document a mold-control step for the customer
  • Stops regrowth after cleaning — prevents mold and odor-causing bacteria from returning to surfaces you have already remediated
  • Works on mixed substrates — labeled for walls, ceilings, pipes, and HVAC duct systems, so one product covers the whole job
  • White finish — leaves a visible white film that shows exactly where you have treated
  • Backed by an SDS and product data sheet — dilution, dwell, and PPE details come straight from the Foster documentation on the product label and SDS

Foster 40-20 Where It's Used

Air-duct cleaning and HVAC service crews apply Foster 40-20 inside sheet-metal and lined duct systems after mechanical cleaning. Restoration and remediation teams use it on walls, ceilings, and pipe runs in homes, offices, schools, and healthcare facilities where mold and musty odors have been an issue. Because it is EPA-registered, it fits jobs where the contract calls for a documented antimicrobial treatment. Review the product data sheet for surface prep and application rates before you start.
