GMA Garnet Premium Blasting Abrasive Media Supplier

BLASTONE HAS BEEN WORKING AS A DISTRIBUTOR OF GMA GARNET FOR OVER 35 YEARS

Over the last 30 years, garnet has become the primary abrasive used for sandblasting in America, Australia, and New Zealand. BlastOne has helped contractors on different projects across the United States and the globe and we understand the requirements that different projects bring.

While there is no such thing as a does-all sandblasting abrasive, GMA Garnet comes closest. It has been the abrasive of choice for blasting multiple materials – steel, aluminium, stainless steel, glass. It has performed tasks as varied as frosting glass, cleaning up stainless steel after TIG welding, and removing corrosion on marine vessels.

GMA Garnet has provided a solution to challenges such as…

Needed as clean a surface as possible – GMA Garnet’s washing and screening process removes any contaminant from the sandblasting abrasive that would remain on the surface after impacting it.

Needed as high a blasting rate as possible – GMA Garnet’s unique crystal structure and geology, combined with engineered blend sizing, ensures a high productivity rate.

Needed to blast with as low as possible abrasive consumption – The same characteristics that ensure excellent productivity when using GMA Garnet also ensure low consumption of sandblasting abrasive per square foot/metre of finished blasted surface.

Needed to change to a non free-silica containing abrasive – Many mined abrasive blasting sands contain high levels of free-silica, the substance that causes the irreversible lung condition, silicosis. GMA Garnet’s free-silica levels are well below international OHS mandated maximum levels.

To get the highest performance and lowest consumption out of GMA Garnet, it is necessary to ensure that you are getting 100 psi compressed air at the blast nozzle. Talk to your BlastOne corrosion control specialist for assessment of the air pressure at your nozzle and, if needed, system improvement recommendations.

Benefits of using GMA Garnet

  1. Fast Blasting = Faster job completion
  2. Lower cost to blast with = blasting faster with less abrasive saves you money
  3. Low Dust = increases your visibility and safety
  4. Better Quality results = cleaner surface for your coating to adhere too
  5. Lower Abrasive Consumption Rate = use less abrasive, clean up less abrasive
