Less Dust, More Productivity

Throughout the world, maintenance and safety managers and contractors select garnet as the cost-effective, safe choice for the toughest blasting applications. Explore the time-saving benefits of GMA ToughBlast™.

Superior Surface Preparation for Coating

Harder, tougher and denser, garnet gets the job done faster without the drawbacks of waste slag. Garnet is two times harder than most Chinese and Indian garnets. Its superior hardness enables garnet to more effectively remove strong coatings without embedment.

Other garnets simply can't match the extraordinarily clean surface that hard, tough GMA garnet creates, increasing your coating adhesion and life.


The Fastest Results at the Lowest Cost

Only ToughBlast™ produces an exceptionally clean surface and uniform profile that keeps your project on schedule and within budget.

Overall, garnet sandblasting requires 30% to 50% less product than other garnets. In addition, it greatly reduces labour, containment and disposal costs because it lacks the high levels of dust and harmful metals that waste slag spreads when it shatters.
