Garnet Abrasive for Blast Cleaning

Garnet is a sandblasting mineral, derived from either Almandite or Andradite deposits.  Almandite garnet is further separated by being either Hard Rock or Alluvial.  It is great for both wet and dry sandblasting applications.  Garnet is a industrial gemstone that creates a profile virtually free of embedment, which makes it excellent for coating adhesion, as well as applications where low or no transfer of grit into the substrate can be tolerated.  We offer Almandite garnet, as well as Andradite type garnets.


  • High hardness.  Garnet will last a long time, making it a very cost effective sandblasting abrasive.  Mohs Hardness is 7 to 8 depending on the type ..
  • Can recycle a number of times, depending on your grit size (generally you can obtain recycle garnet twice, perhaps more when starting with a coarse grade).
  • Environmentally Friendy!  It is thus often used to blast stuctures residing over or next to bodies of water where contamination by the blasting media itself is a concern.
  • Garnet is safe and non toxic with very low free silica levels (generally less than 1%).
  • Low Dusting.  Garnet is a fast and clean blast media.  Often referred to as “Poor Man’s Aluminum Oxide”
  • Excellent for coating prep, surface prep use.  Garnet will leave a profile that is almost free from embedment, troughs, and peaks.
  • Multiple Shipping Points around the country.
