sandblasting is a surface preparation technique used in various industries, such as automotive, aerospace, and construction. It involves propelling abrasive materials at high speeds to clean, strengthen, or polish surfaces. Sandblasting is effective for removing rust, paint, scale, and other contaminants from metal surfaces, making them ready for painting or coating. It is also used to create a matte or textured finish on surfaces. Sandblasting can be done using various abrasive materials, such as sand, glass beads, or steel grit, depending on the desired finish and the material being treated.
