The term Sandblasting is no longer foreign in the world of Shipping (Marine), Industry and civil construction at this time. But what exactly is sandblasting?

Sandblasting

Sandblasting is the process of spraying abrasive material in the form of silica sand or steel grit with high pressure on a surface with the aim of removing contaminating materials such as rust, paint, salt, oil and others. In addition, sandblasting also aims to create a profile (roughness) on the surface of metal or others so that good adhesion can be achieved between the metal surface and protective materials such as paint. The level of roughness can be adjusted according to the size of the sand and its pressure. Sandblasting is very important, because the success or failure of a painting depends greatly on the level of cleanliness and the level of adhesion between the paint and the surface as well as the level of density and smoothness of the paint itself.
