An applicator gun for a two-part material includes a hand grip and a barrel. The barrel extends generally transverse to the hand grip and has a free end. A feed valve set is positioned at about a juncture of the barrel and the hand grip, and includes first and second feed valves, each having an inlet. An actuator is operably connected to one or both of the feed valves for opening and closing the valves. A mixing nozzle is disposed at the barrel free end and has first and second inlets and discharge openings. The discharge openings are formed at a discharge end of the nozzle. Feed tubes provide flow communication between the feed valves and the mixing nozzle inlets. The actuator opens the feed valves to feed the two part material through the applicator gun and the two-part material is maintained separated through discharge at the mixing nozzle.
