ABSTRACT:
An apparatus for applying joint compound is externally powered, preferably using compressed air. The preferred apparatus has a hollow tubular storage body that is connected to a supply of compressed air, and a movable plunger positioned within the hollow tubular storage body. The plunger has a pair of rubber seals that contact the inner wall of the storage body. A supply of joint compound is inserted into the storage body on the side of the plunger opposite the side of the plunger that can be exposed to pressurized air. Pressurized air can be supplied by the user against the plunger to push the supply of joint compound out of the storage body through a mud supply head. An applicator tip is connected to the mud supply head and can be connected to either a flat joint attachment or a corner joint attachment. Alternatively, other attachments can be used such as a texture gun attachment, a fireproofing attachment, or a water cleaning attachment.
