Proven performance in surface preparation


High productivity

Cut blasting hours by 30-50%* compared to slag abrasives. GMA ToughBlast™ performance has been demonstrated through rigorous product testing and a track record of success in applications worldwide.


Cost-effective blasting

Deliver fast results at the lowest cost. GMA Garnet™ can provide significant savings in abrasive consumption, blasting hours, and disposal costs for your project. Overall, garnet sandblasting generally requires 30–50% less product than waste slag.*


Ideal surface finish

GMA ToughBlast™ achieves an exceptionally clean surface and high peak density. Our uniquely hard and tough garnet blend cuts through resilient coatings, allowing operators to prepare surfaces quickly for inspection and recoating.


Safe and compliant

Have complete peace of mind knowing GMA Garnet™ meets all industry, government safety, and environmental standards. Blasting the purest, cleanest garnet means less dust, leading to better operator visibility and less worker risk.


Why engineered blends perform better

GMA’s sharp, angular hard rock garnet cuts through the toughest, thickest coatings up to 30 mil and creates a consistent surface profile up to 4.0 mil. With the addition of fine, subangular alluvial garnet, ToughBlast™ removes all traces of surface embedment and contaminants. This dual-action performance ensures speed and efficiency on the toughest coating removal jobs and improves blasting production rates.
