Duct sealant grey seals seams, joints and gaps in HVAC ductwork to stop air leaks.
Apply to clean, dry surfaces. Let it cure before running the fans.
What is a duct sealant grey?
Duct sealants and aluminium tapes make ductwork airtight. Sealant is brushed or gunned into seams and flange joints, while aluminium foil tape seals insulation joints and small gaps.
Leaky ducts waste fan energy and cooling. Therefore, sealing every joint is a low-cost way to improve an HVAC system.
