When used in conjunction with sheet metal:
Apply by brush, hand, trowel or spray. PROSeal should be applied to duct connections according to all applicable HVAC standards. Apply to inside of female fittings and outside of male fittings. Assemble the joint. Brush sealant over the assembled joint. Thoroughly cover joint and screws with a 50 – 75mm wide band. Assembly should cure for 24 – 72 hours before pressure testing the system.
