Sandblasting is an operation that allows you to clean up a surface from incrustations, ironworking residues, old varnishes, oxidation and rust or to obtain a surface that ensures a good anchorage for subsequent anticorrosive or protective treatments.

Sandblasting is carried out by special machines (sandblasting machines) using a high pressure jet of abrasive such as sand, metal grit, etc. or abrasive mixed with water to reduce the fumes or to avoid the formation of spark. The jet, directed on the surface, removes the encrusting material by impact and abracion; directed on clean surface, the erode slightly making it rough and therefore suitablefor retaining paints, adhesives, etc.
