captive shot blasting fires a highly abrasive steel shot at the surface at high velocity. The shot hits the surface and rebounds, and the shot and debris then enters a separator where the dirt and debris are separated from the shot. The shot is then recycled back to the wheel and reused. When carried out properly by experienced operatives little or no dust is emitted into the atmosphere.
Shot blasting leaves the surface dry, clean and profiled completely ready for the application of new coatings and provides the ideal roughened surface for the adhesion of any new coating or surface. Shot blasting is recommended by most coating specialists as it produces the ideal surface for their applications.
