Coarsest Grade Engineered Blend for Extreme Jobs
GMA’s ExtremeBlast™ is GMA's coarsest garnet grade engineered for the most resilient coating removal jobs. The unique blend of both coarse and fine garnet is ideal for industrial maintenance in refineries, shipyards and offshore platforms. The angular coarse garnet removes resilient industrial coatings, and the durability of the sub-angular alluvial garnet helps sweep off remaining surface contaminants.
Throughout the world, garnet is recognised as the leading high performance, cost efficient and safe choice for a variety of blasting applications.
