GMA PrecisionBlast 120 Mesh Garnet

SKU: GA120552200

GMA PrecisionBlast is an abrasive blasting media ideally suited to minimizing substrate damage and where a frosted or matt finish is required.



While removal of mill scale is possible with GMA PrecisionBlast 120 mesh garnet, it’s prime application is for where coarser grades would create unacceptable substrate damage. Substrates susceptible to damage from coarse abrasives include non-ferrous metals (stainless steel, aluminum and titanium), stone and glass. In addition, the fine sizing of GMA PrecisionBlast 120 mesh garnet means that it can create an etched or frosted effect.

GMA Garnet is available from BlastOne throughout the USA. BlastOne’s stock-holdings includes multiple different grades to suit every blasting challenge. GMA’s ISO Quality Management System ensures consistency, both in size and cleanliness.
