Abrasive blasting is a surface treatment process that uses high-pressure air or water to propel abrasive materials against a surface. This technique is commonly used to clean, smooth, or shape various materials, including metals, plastics, and glass. The abrasives can include materials like sand, steel shot, or glass beads, depending on the desired finish and application. This method is often employed in industries such as automotive, construction, and manufacturing to prepare surfaces for painting or coating. It can effectively remove rust, paint, and other contaminants, ensuring better adhesion of protective finishes and enhancing the overall appearance of the material.
