Sandblasting technique

Sandblasting is a mechanical process of cleaning, surface preparation, and impurity removal that uses a mixture of abrasive and compressed air to propel particles against a surface. This technique is widely used in various industries such as aerospace, automotive, marine, and construction.

Among the main advantages of sandblasting are the removal of rust, paint, scale, and other unwanted coatings, as well as surface preparation for the application of paint, coatings, and other surface treatments. Additionally, sandblasting improves the adhesion of coatings and extends the lifespan of parts and structures.

Compared to other abrasives, GMA garnet offers a wide range of competitive advantages, including:
