An applicator includes a bore for containing a sealant component, a piston moveably positioned in the bore, a plunger member connected to the piston with a distal end disposed within the bore and a proximal end depending from the bore, a distal outlet communicating with the bore and connectable to a gas source, and an actuating member carried by the proximal end of the plunger member to move with the plunger member as the plunger member moves along the bore. The applicator may be used in a system with a gas source connected to the distal outlet, and a control unit connected to the actuating member and the gas source, the control unit adapted to supply gas to the distal outlet from the gas source essentially simultaneous with a force applied to the actuating member.
