  • Made for unfaced fiberglass liner and duct board — surfaces the exact insulation types found inside lined HVAC duct
  • Waterbased and low odor — cuts fumes on occupied-building jobs compared with solvent products
  • Quick setting — sets fast so you can move through a duct system without long dwell delays
  • Black finish — blends with the dark interior of lined ductwork for a uniform look
  • Backed by an SDS and product data sheet — coverage rate and application come from the Foster documentation with the product

Foster 40-11 Where It's Used

Air-duct cleaning and HVAC service crews apply Foster 40-11 to resurface unfaced fiberglass duct liner and fiberglass duct board after cleaning. It fits homes, offices, and institutional buildings where interior liner has degraded and needs a fresh sealed surface. The low-odor waterbased formula suits work in occupied spaces. Check the product data sheet for coverage rate and recoat guidance before you spray or brush.
