Abstract: During blasting work, large quantities of blasting material (granules, glass, beads, slag and sand) together with residues of blasted color coating are projected over a large area after impact with the surface being blasted.

Abstract: The present invention is an overspray collector and method of collecting overspray. The overspray collector provides a device and method to intercept overspray produced by spraying coating material onto any relatively-flat surface and preventing air pollution by capturing such pollution at its source.
