A handheld pressurized hopper gun for use in patching acoustic ceilings and repairing cracks and damage in walls and ceilings by applying a texturized sealing compound thereto is disclosed. The pressurized hopper gun is typically employed where plaster walls and ceilings are being refurbished due to damage thereto. The handheld pressurized hopper gun includes a spray gun, a pressurized sealed hopper mounted over the spray gun and containing a sealing compound, and a pressurized air input. The pressurized air input provides low pressure air from an air input housing to an air regulator and the spray gun and to a cock valve and the pressurized sealed hopper. The spray gun has a handle having a first air passage formed therethrough, a movable hollow plunger shaft having a second air passage formed therethrough, a nozzle for seating an end of the hollow plunger shaft and an orifice formed through the nozzle. The orifice and the second air passage are aligned and communicate with the first air passage so that low pressure air is constantly passing through the spray gun. A trigger is included for unseating the hollow plunger shaft from the nozzle so that the sealing compound is dispensed out the orifice under air pressure. A flexible air line connecting the air input housing to the pressurized sealed hopper includes a pressure gauge combined with the cock valve for controlling the low pressure air supplied to the sealed hopper.
