ABSTRACT:
An apparatus and method for applying a blasting media, comprised of at least first and second separate types of particles, to a surface to be treated. Each type of particle may comprise a core coated with a desired component, e.g. abrasive, absorptive, polishing, etc., and the components are selected so as to minimize the density variation of different types of media being combined with one another for the surface treatment. The different types of particles are mixed with one another prior to application to a surface to be treated. The mixing may occur in a mixing tank prior to use, in the media supply conduit prior to the nozzle, at the discharge outlet of the nozzle, or just prior to contacting the surface to be treated. By employing different types of particles, cleaning and reuse of the media is facilitated while also minimizing the amount of media consumed per unit area of wall to be treated. In addition, an operator is able to custom blend the media, during use at a jobsite, to maximize surface treatment, per pound of media, and minimize the generation of disposable waste.
