ExtremeBlast is GMA Garnet’s range of engineered abrasive blasting media. This abrasive is a blend of alluvial and rock garnets. However, 36 mesh is 100% rock garnet. Consequently, the sharpness of the abrasive is maximized. As a result it is excellent for removing flexible or rubberised coatings.

Throughout the USA, BlastOne stocks GMA Garnet. Different grades are available to suit different blasting challenges. GMA’s ISO Quality Management System ensures consistency. Both in size and cleanliness.
