Sand Blasting is the process of smoothing a surface with abrasive materials, like sand, ceramic grit, or aluminum oxide. The abrasive materials are pushed out at a high velocity with compressed air.
Historical Context
The origins of sand blasting trace back to 1870, when Benjamin Chew Tilghman patented the process. Since then, the technique has evolved with the inclusion of safer and more efficient abrasive materials.
Typical Use Cases
Sand blasting works well on thick rust and old paint. Shops use it to strip cars, clean steel beams, and shape rough concrete. It can prep surfaces for welds or thick coatings. It’s common in shipyards, bridges, and big repair shops.
