Industrial sandblasting uses high-pressure air or steam to blast abrasive particles at surfaces, stripping away rust, paint, and grime. It’s a messy but satisfying process that preps metal, concrete, or wood for refinishing—think of it as a power wash with grit. The abrasive, like silica or steel shot, is recycled, and operators gear up in suits and respirators to stay safe. The result is a clean, rough surface ready for coating or restoration.
