Dependable, durable and flexible air tight adhesive caulk for connections between interior or exterior air barriers and/or uneven substrates. It can be used on the interior or exterior of the building.


Available in:

300 ml (10.5 oz) cartridge - 3/16″ to 1/4″ bead will cover 9.14 m to 13.73 m (30 to 45 linear ft)

600 ml (20.3 oz) sausage - 3/16″ to 1/4″ bead will cover 18.28 m to 27.43 m (60 to 90 linear ft)

Coverage in linear ft. will depend on width of bead applied and roughness of substrate.
