Shot blasting and grit blasting are two common methods used for surface preparation and cleaning in various industries such as construction, automotive, aerospace, and manufacturing. While both methods are similar in principle, there are some key differences that set them apart. Shot blasting Shot blasting is a process in which small metallic or non-metallic balls, also known as shot, are propelled at a high velocity onto a surface to clean or prepare it. The shot is typically made of steel, cast iron, or stainless steel, and is used to remove rust, scale, old coatings, and other contaminants from surfaces. The process is usually done in a closed system to minimise dust and noise. Grit blasting Grit blasting uses abrasive materials such as sand, aluminium oxide, or silicon carbide to clean or prepare surfaces. Unlike shot blasting, grit blasting is not limited to metallic surfaces and can be used on a wide range of materials, including concrete, brick, and stone. It is ...
