what is sandblasting

Sandblasting, also known as abrasive blasting, is a process that involves the use of a powered machine to spray abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants. Sandblasting leverages the abrasive properties of sand to create smoother surfaces with fewer physical imperfections and flaws. The process involves pouring sand into a sandblasting machine, which is then connected to an air compressor. The highly pressurized sand is then propelled at the surface at an extremely high speed, acting like sandpaper to scrape away excess materials and smooth the surface. Sandblasting can be used to refurbish buildings, clean boat hulls, create works of art, and produce three-dimensional signage. It is also used to remove contaminants from surfaces, strip existing paint and rust from the body of a vehicle before painting, etch glass, and remove scale from steel.
