Screw the can tightly onto the thread of the pistol and shake the pistol well around 30 times so that the can contents are mixed and an optimal foam quality is achieved. Adjust the foam bead with the setting screw and spray the foam out using the trigger. Only fill joints and cavities up to a third as the foam will expand. Cut off any excess, fully hardened foam with a knife.
