Blasting painting is a finishing technique that combines a surface cleaning process (blasting) with a coating process (painting):

The process of cleaning the surface of a material by spraying abrasive materials such as sand, glass powder, or steel grit at high pressure. Blasting can remove rust, paint, and other impurities.

The process of coating the material with paint using roll, spray, or brush methods. 

Blasting painting can be used on various types of objects, such as jewelry, ships, or buildings. This technique can make the surface of the object more neat, smooth, and durable.
