Abrasive Garnet is intended for Private Blasting for both confined and open-air environments.

It is free of free silica, so it does not cause any harm to humans or the environment and has great physical properties.
It may be an alternative to Sandblasting as it is prohibited by law.


It is also used in some medium grain size for waterjet cutting.

Available grit sizes Typical Applications
12 Coal Tar-based Surface Preparation
16 Surface preparation for 500-600 µ thickness – dry layer
30 Surface preparation for 300-400 µ thickness – dry layer
40 Surface preparation for 200-300 µ thickness – dry layer
