Why blast with GMA Garnet Blasting media?

High performance abrasive blasting.

GMA Garnet Abrasive media is a naturally occurring mineral abrasive, low in free silica and heavy metals. Therefore it is safe to use and handle. Low consumption rates reduce abrasive and disposal costs. GMA’s particle size provides a blasted surface profile. Making it suitable for most high-performance paint coating systems. GMA Garnet will blast faster than steel grit, providing higher productivity. As a result, it has a lower cost per square metre of blasted surface.

Low Dust/Low Mud Abrasive Blasting.

GMA Garnet contains virtually no fines. Consequently it does not emit clouds of dust when used dry or mud when used wet. GMA Garnet is suitable for all wet blasting systems. This includes systems such as Graco Ecoquip, Torbo and Amphiblast.

International Standards Compliant Blasting Media

GMA Garnet complies with all relevant International Standards. This includes ISO11126 and ISO11127. GMA Garnet sand has very low/negligible free silica. It also has extremely low levels of soluble chlorides. Traceable compliance test certificates are available for every batch.
