Garnet Abrasive for Blast Cleaning (Wholesale)
Our price:

Garnet is a sandblasting mineral, derived from either Almandite or Andradite deposits.  It is appropriate 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.

The simplest way to describe garnet would be "Clean & Fast".


  • High hardness.  Garnet will last a long time, making it a very cost effective 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.
  • Excellent for coating prep use.  Garnet will leave a profile that is almost free from embedment, troughs, and peaks.

  • Color: Depends.  Pink, Red/Brown, Grey/Brown 
  • Density: 135 lbs/ft3 to 150 lbs/ft3

Excellent For:

  • Tanks and other confined spaces where use of a low dusting abrasive is necessary.
  • Dry docks, Bridges, Shipyards - a great abrasive to use where water contamination is a concern.
  • Aluminum and Fiberglass surfaces
  • Hangar decks
  • Powdercoating, denim blasting
  • Industrial Painting

Sizing and Profile Information:  (!)  NOTES:  Anchor patterns will vary tremendously based on other variables such as hardness & type of steel, level of corrosion being removed, blast angle, blast distance from the steel, etc.  There are also many differnet types of garnet available, each having a different result when used in a blasting operation. 

Some garnet will cut fast and be recycleable, but carry a higher price.  Other types are rounder, and slower cutting but carry a lower price.  For example, crushed garnet mined here in Idaho is sharp without rounded edges.  It will cut fast, come in larger sizes, and you can recycle it one or two more times than Alluvial garnet.  Alluvial Indian garnet  is essentially beach sand, which has rounded edges, so it is slower cutting, but less expensive.  Alluvial garnet does not come in sizes larger than a 3060 typically, because it is not a crushed product.  

Make sure you indicate to us what your required mil profile is, the type of steel you are blasting, and what you are removing, so we can best match a garnet to suit your operation.

16 - Very Coarse.  ideal for blast rooms due to the number of times you can recycle.  Provides a 3-4 mil profile on blasting steel, bridges, ships and tanks.

36 – Coarse.   Produces a 2 - 3 mil profile on steel surfaces.  Generally used for thick coatings, marine fouling, and rust.

30×40 – Intermediate.  Produces a  2 –2.5, maybe 3 mil profile on steel surfaces.  Used on heavier coatings up to 40 mils, and rust.  
30×60 Medium.  Produces a 2.0 – 3 mil profile on steel surfaces.  Considered to be an overall workhorse grade for new steel and maintenance for coatings up to 20 mils.
80 Mesh – Medium Fine.  Produces a 1.5 - 2.0 profile on steel surfaces.  Great for aluminum and other sensitive substrates.  Also perfect for marine aluminum applications, and hydro blast cleaning operations.
100 Mesh – Fine.  Produces a 1.0 – 2.5 mil profile on steel surfaces.  Also can be used on aluminum and fiberglass, as well as for rust removal and mill scale on new steel.  This grit size will polish new aluminum.  It is also a perfect waterjet cutting abrasive.
