Safe and compliant

GMA products are natural, chemically inert minerals with no toxic metals and little-to-no worker or environmental risks, including minimal dust during blasting - a safe choice for sensitive environments. GMA Garnet™ meets all industry and government safety and environmental standards.


What makes GMA Garnet unique?

GMA Garnet™ is an inert natural mineral that outperforms other abrasives due to its inherent hardness, toughness, density, and angularity. These qualities, when combined with the recommended equipment and air pressure, provide teams with unmatched performance, such as reduced blasting hours, lower abrasive consumption, and excellent control over how much material is removed.

Case study

Incredible control, minimal dust and noticeably lower consumption

The owner of Metal Revival in Columbia, Tennessee in USA has been using crushed glass for his wood and metal restoration projects for four years. However, the limitations to using glass abrasives caused him to try GMA Garnet abrasives.

“I couldn’t believe the control I had. It flows through my fingers like liquid yet generates minimal dust when blasting. The abrasive consumption was noticeably lower compared to glass abrasives. I’m sold on GMA Garnet™.”
