Garnet Abrasive Media


Garnet AbrasiveGarnet abrasives are often used as an alternative to silica sand as it produces less dust and is safer than its hazardous counterpart, silica sand. When used properly abrasive blasting with Garnet provides comparable production rates as silica sand.

The natural roundness, hardness, durability and high density characteristics make Garnet suitable for wet or dry abrasive blasting.

Due to its hard and heavy abrasive characteristics, Garnet can increase productivity AND reduce amount of abrasive used.

Garnet can be used in a wide variety of abrasive blasting applications, including blast rooms and shipyards.

Abrasive blasting with Garnet is safe for use on metals, brick, marble, granite, limestone, concrete, travertine and more.

Use large grains for quick projects; use small grains for a finer finish.

Typical hardness is 6.5 – 7.5 on Mohs scale or 982 – 1161 on Vickers.


  • Cuts fast
  • Uses less abrasive
  • Lowers disposal cost
  • Environmentally friendly – no heavy metals
  • Lower dust production
  • Better visibility while blasting
  • Recyclable up to 5 times
  • Easy clean-up
  • Provides superior surface for coating adhesion
  • Non-Toxic
  • Does not draw moisture
  • Does not compromise coatings


  • Size 16 (Extra Coarse): removes very thick coatings (50-60+ mils) and rust. Can obtain a 4+ mil profile on steel.
  • Size 36 (Coarse): removes thick coatings (20-50 mils). Typical mil profile between 3.5
  • Size 30 x 40 (Medium Coarse): removes heavy coatings and rust (20-40+ mils) while maintaining 4.5 on steel
  • Size 30 x 60 (Medium): “Workhorse” grade used for new steel and maintenance work on coatings up to 20 mils while maintaining 3.5 on steel
  • Size 80 (Medium Fine): Used on aluminum and other sensitive substrates, typically produces a 2.0-2.8 mils on steel, used as a waterjet cutting abrasive
  • Size 120 (Fine): Used on aluminum and fiberglass and for the removal of rust and mill scale on new steel, producing 1.5-2.5 mils on steel

Abrasive blasting with Garnet provides an efficient, cost-effective, environmentally-friendly, and operator-safe alternative to silica sand abrasives.
