One gun for spraying GFRC Facecoats & Backcoats. Its inverted shape allows you to reach deep into molds that conventional pistol style guns can’t fit into. It has a large 2.5 gal hopper with built in handle for superb control. The high vacuum venturi design creates a tremendous draw from the hopper to spray thick mixes with ease. The single button trigger makes for simple operation. This unique gun enables you to do in minutes what took you hours, resulting in increased productivity and savings on labor costs. Due to the gradually curved outlet flow path, the cleanup is remarkably simple.
