Sandblasting is an abrasive surface treatment that uses high-pressure air or water to propel abrasive media, such as steel grit or aluminum oxide, onto a surface. This process effectively removes rust, paint, scale and contaminants while enhancing adhesion for coatings and improving surface texture. It is widely used in industries likeautomotive , construction and manufacturing to clean, prepare or restore metal, concrete and wood surfaces.Abrasive media vary in hardness, shape and size (typically #120 to #220), affecting the final surface quality. Steel grit (40-65 HRC) is commonly used for its angular shape, making it ideal for cleaning, etching and surface preparation. Sandblasted parts achieve a clean, matte finish that enhances coating adhesion. Proper safety measures, including protective gear and ventilation, are essential to minimize dust exposure.
