Get a cleaner surface faster, with minimized OSH risks

Approved by leading paint and coating manufacturers around the world, GMA is meeting the challenge of the wind power industry by offering high-performance abrasives for onshore and offshore wind turbine installations and maintenance, including towers and foundations, turbine components, blades and other equipment.


High productivity

Achieve your specified surface profile faster than alternate abrasives.


Low consumption

Complete the job with far less abrasive, reducing costs in abrasive purchase, transport, and disposal.

High Peak Density

High peak density

Generate higher peak density over alternate abrasives for unmatched coating adhesion and integrity.

Surface quality

Low embedment

60% of the average slag-blasted surface is embedded with residual abrasive. Garnet results in minimal embedment.

Hazard mask

Low dust

GMA Garnet™ offers the closest thing to dustless blasting, drastically improving operator visibility and reducing site contamination.


Low safety risk

Garnet is an inert mineral with little to no heavy metals creating worker risks or environmental hazards.

Wind turbine installation and maintenance

  • When high surface profiles and SP-10 cleaning standards exist for coating applications in extreme environments GMA Garnet is exceptionally well suited
  • High blasting and cleaning efficiency, leading to lower abrasive consumption, and lower clean-up and disposal costs
  • Exceptional surface cleanliness with minimal abrasive embedment, providing better corrosion resistance and substrate integrity
  • When abrasive recovery is possible GMA Garnet™ can provide a high level of abrasive reusability through recycling onsite
  • If abrasive recovery is not possible, GMA Garnet™ is an inert, natural mineral, with little to no heavy metals, reducing the risk of environmental contamination as well as worker risks and hazards.
