How does garnet outperform slag abrasives?
Tougher, harder grains
GMA Garnet™ is tougher and harder than slag abrasives. Its denser crystal structure makes it more resistant to breakdown, ensuring high-performance low dust blasting at reduced cost.
Higher productivity
GMA Garnet™ completes projects faster because it is harder and denser than slags. Additionally, the cleaner results eliminate costly rework, helping pass inspection the first time.
Lower dust levels
GMA Garnet™ produces less dust than slag abrasives. This improves operator visibility during blasting, speeds up the process, and reduces onsite contamination.
Cost efficiency
The combination of higher productivity, reduced dust, and elimination of rework boost blast efficiency and reduce downtime, leading to overall lower project costs.
What is an engineered blend?
Abrasives that blast smarter
GMA engineered blends contain a mix of coarse and fine garnet grains that achieve the optimal balance between cutting and cleaning power — at a faster rate. This makes GMA Garnet™ suitable for a wide range of applications, from shipbuilding to construction. Numerous case studies highlight its exceptional performance, showcasing significant time savings and enhanced surface quality.

Frequently asked questions
Abrasives aren’t made equal — here’s more on why. For more information on GMA Garnet™ and switching to garnet abrasives, visit the FAQs library.
How does GMA Garnet™ improve productivity in abrasive blasting?
GMA Garnet™ improves productivity through high blasting speed and efficiency. Its hardness and angularity ensure rapid cutting and consistent surface profiles, reducing the time needed for surface preparation. Lower dust generation enhances visibility, allowing operators to work more accurately and quickly, with fewer stoppages waiting for dust to clear.
These factors combine to increase overall productivity, enabling faster project completion and lower labor costs. In addition, the reduced need for cleanup and equipment maintenance further boosts productivity and cost savings.
How does the hardness of GMA Garnet™ affect blasting performance?
The hardness of GMA Garnet™, typically around 7.5-8.0 on the Mohs scale, ensures rapid and efficient cutting of tough coatings and rust. This results in faster job completion and a more consistent surface profile.
How does the low dust generation of GMA Garnet™ enhance productivity?
Low dust generation enhances visibility during blasting, leading to better accuracy and reduced labor and clean up. It also improves worker safety and reduces the risk of respiratory issues compared to other abrasives.
Why should I replace my slag abrasive with GMA Garnet™?
Switching to GMA Garnet can offer several benefits over slag abrasives, even if you haven't encountered issues with slag. GMA Garnet’s superior hardness and recyclability reduce consumption and overall costs. The lower dust levels improve worker safety and visibility, potentially reducing health risks and cleanup time.
Additionally, GMA Garnet provides a more consistent surface finish, which can improve the quality of your work and customer satisfaction. The overall costs, including labor, equipment maintenance, and cleanup, can be significantly lower with GMA Garnet due to its efficient performance and recyclability. Even if slag has worked well for you, the enhanced performance and cost savings of GMA Garnet can be a valuable upgrade.
