Abstract: An apparatus for applying a coating material such as paints or sealants, to a desired surface area, such as a wall, building or a billboard. The apparatus includes at least two vertical support members that are laterally supported by a horizontally secured beam. In between the vertical support members is a track that is movably secured generally parallel to the horizontal beam and can traverse up and down along the two vertical support members. A paint assembly is movably secured to the track. The paint assembly is used to store and spray the paint onto the desired surface and can traverse along the track. The apparatus is connected to and controlled by a control system. The control system allows the user to input the dimensions of the surface to be painted as well as the desired image to be painted.
