An inexpensive pneumatically-operated apparatus is disclosed for spraying a broad range of viscous materials that atomizes the sprayable material without using propellant gases, and can be filled with bulk texture or other fluid coatings. A container removably locks onto the bottom of a sealing disk, consisting of a dip tube, an elbow, an air jet member, an equalization port, and an equalization tube. A cap is selectively united with the sealing disk and the container. The user fills the container with the sprayable material, attaches it to the sealing disk and cap, and connects to an external air supply device. A spray nozzle is used to adjust the type of spray, and the user holds up the apparatus as one would hold an aerosol spray can. If the user covers the control orifice, trapping the air inside, air pressure builds inside the container and the apparatus atomizes and sprays the sprayable material until the supply is consumed or until the user removes the covering over the control orifice to stop spraying.
