Sandblasting is a process that uses high-pressure air to propel abrasive materials, like sand, against a surface. This technique is commonly used for cleaning, smoothing, or shaping various materials, including metal, glass, and wood. The force of the abrasive particles removes dirt, rust, or old paint, making surfaces ready for finishing or painting. The equipment for sandblasting typically includes a compressor, a blasting nozzle, and a container for the abrasive material. Safety precautions are essential, as the process can create dust and flying particles. Proper protective gear, such as masks and goggles, is necessary to ensure the safety of the operator.
