Foster 40-30 Fungicidal Protective Coating for Ducts and Surfaces

Foster 40-30 is an EPA-registered fungicidal coating that dries black. The 5 Gallon coating prevents mold regrowth and the spread of odor-causing bacteria on walls, ceilings, pipes and HVAC duct systems.

Foster 40-30 Coverage and Use

  • Black finish for lined duct interiors — blends with dark liner where a white coating would stand out
  • EPA-registered fungicidal formula — documents the mold-control step contractors need to show the customer
  • Stops regrowth after cleaning — holds back mold and odor-causing bacteria on remediated surfaces
  • Labeled for mixed substrates — covers walls, ceilings, pipes, and HVAC duct systems with one product
  • Backed by an SDS and product data sheet — dilution, dwell, and PPE come from the Foster documentation with the product

Foster 40-30 Where It's Used

Air-duct cleaners and remediation crews apply Foster 40-30 inside HVAC duct systems and on walls, ceilings, and pipe runs after mechanical cleaning. The black finish suits lined duct interiors and darker surfaces where a white film would be visible. Because it is EPA-registered, it fits contracts calling for a documented antimicrobial step in homes, offices, schools, and healthcare buildings. Review the product data sheet for prep and application rates.
