Abstract
A system and device for adding dry media to a liquid stream or fan-shaped spray of paint or other suitable liquid material emerging from a spray gun. The dry media are added to the liquid stream by connecting a nozzle spray guard having hose connectors with injectors on opposite sides of the guard. The injection jets are constructed to add dry media at between 45 degrees and 90 degrees to the liquid stream exiting the nozzle of the spray gun. Wing-like appendages on the nozzle guard assist in containing the granular material in the path to impinge on the liquid stream. The liquid stream containing the uniformly mixed dry media or granular material is sprayed on the surface to which it is being applied.
