Abstract:
An apparatus for spraying fluid drywall material onto a work surface, the apparatus comprising:a generally cylindrical tank adapted to be filled with the fluid drywall material;a spray tool configured to direct the fluid drywall material on to said work surface;conduit means connected between the tank and the tool such that there is material and air flow communication therebetween;an air supply connected to the tank and to the conduit means such that there is air flow communication therebetween; andmeans for controlling the air pressure within the tank;wherein when the air pressure-controlling means is closed to increase the air pressure within the tank, air is forced through the conduit means and the spray tool, and the fluid drywall material is urged from the tank through the conduit means and the spray tool, such that the fluid drywall material is sprayed onto the work surface, and when the air pressure-controlling means is opened to decrease the air pressure within the tank, spraying of the fluid drywall material onto the work surface is stopped.
