Glass Abrasive Blasting Media (Crushed Glass)

Glass Abrasive Blasting Media (Crushed Glass)

Our crushed glass abrasive blast is made from 100% recycled glass. This is an inert abrasive that is recommended by NIOSH as a substitute for slag and mineral abrasives.  Contains no heavy metals, no free silica, and is therefore great for blasting projects where it is impractical to recover lost or spilled spent abrasive. 

Crushed glass offers significant cost savings over using plastic beads, soda blast, and glass beads.  Because it is more aggressive, it is able to remove corrosion and tougher coatings that other medias cannot, such as thick and rubbery elastomeric coatings.

Glass blasting sand is very economical, available in a variety of grit sizes, and through a wide variety of grades, can achieve all MIL Profiles.  We sell glass blasting media from a variety of different manufacturers, with locations all around the country.  This is a recycled glass product and should be shipped from a location closest to you.   Please use our Quote Request Form.

Benefits of Glass Blast:

  • Efficiently Cleans steel, aluminum, wood, concrete, stone, fiberglass
  • Excellent replacement to silica sand
  • Glass Blast will leave a clean, bright finish to metal surfaces
  • Excellent for achieving an aggressive profile for coatings, including cathodic protection and overlay performance
  • Glass delivers very low particle embedment (less than 2%) which produces a whiter (SP-10) finish to the substrate.
  • Lighter weight than most abrasives.  Contractors report back that they use at least 25% less abrasive (some say up to 50% less) when using glass as compared to mineral slags.
  • SAFE - no free silica, is chemically inert and non toxic.
  • Inert - can use it around water
  • Mohs Hardness of 6.0 - similar to slags.
  • Superior rust-back performance when compared with mineral/slag abrasives. 
  • Contains No Beryllium like mineral slags do.
  • Uniform Density
  • Great for thick, softer coatings because it is a lighter weight abrasive.  It does not "bounce" back off the surface. It cuts it like a knife.
  • Great for concrete and leaves no residue, discoloration, no ferrous impingement, etc.
  • Excellent additive for seal coating operations!
  • Excellent replacement for soda blasting due to its lower cost and it will not leave a PH imbalance on the substrate (which often requires a PH wash solution so that the paint will adhere).  Glass will also cut through rust, and soda blast will not.
  • Excellent replacement for corn cob blasting log homes as it will not embed into the wood, and thus you do not have to hand sand after blasting.  (This can equate to an 80% time savings over corn cob.)
  • 100% recycled post-consumer bottle glass  It is a GREEN abrasive!  100% recycled glass.

Sizes and corresponding achievable MIL Profiles - available from multiple locations, packaged in 2000 lb pallets (40, 50 lb bags) or 3000 lb tote bags.  All product sold in pallet quantities only.

  • #1040: Coarse. This grade will remove heavy rust, thick coatings, and barnacles. Great for concrete, structural steel, heavy tanks.  MIL Profile:  3.0+ on steel surfaces
  • #2040 Medium Coarse.  This blend of grades is great for light paint and rust removal in shipyards, on bridges and tanks.  Great for all general blasting needs.   MIL Profile:  2.5+ on steel surfaces.
  • #40/70 Medium.  Used on stainless steel for wet/dry blasting of light mil scale, maintenance work, graffiti and restoration.  Excellent for log home blasting and auto paint stripping (we recommend a PSI at about 45-50 when blasting thinner metal such as for auto restoration), as well as other light duty work.  MIL Profile: 1.0 to 2.0 on steel surfaces.
  • #70/100:  Fine. Great on softer metals and substrates.  Excellent for etching and degreasing on aluminum, car parts and wood.  Works as a good substitute for soda blasting.   MIL Profile: 0.5 to 1.0 on steel surfaces.

Sizes and corresponding achievable MIL Profiles - available mainly only out of the NORTHWEST USA, packaged in 3000 lb pallets (60, 50 lb bags) or 3,300 lb tote bags.  All product sold in pallet quantities only.  BLASTOX IS AN OPTION.

  • Coarse #16.   3.0 – 4.0 Mil Profile.  Heavy rust, barnacles and thick coatings. Excellent for concrete, structural steel, tanks, barges, etc. Used as a blending stock for recycling blast operations.
  • Coarse/Medium #16/30, 3.0 – 4.0 Mil Profile.  Great for rust and paint removal on ships, bridges, tanks.
  • Medium/Fine # 30/50, 2.5 – 3.5 Mil Profile.  Great overall general abrasive for paint and rust removal.  It is also great for blasting concrete for aggregate exposure, shipyard work, structural steel, and elastomeric coatings.
  • Fine #50, 1.5 -2.5 Mil Profile.  Fast and aggressive size for all finer blasting requiring a smooth, clean finish, excellent for powder coating, auto paint stripping.
  • Super Fine #70, 1.5+ Mil Profile.  Also great for powder coating and auto restoration.  For use on substrates where minimal etching and profiling is preferred, such as aluminum or fiberglass.  This size is commonly used for log home blasting as well.
  • Powder Fine #105F, very low profile.  Substitute for soda blasting media.  For very fine cleaning, brightening, deburring, and fine honing with no damage to the substrate.  Great for graffiti and soft metals as well as tile and brick .

Sizes and corresponding achievable MIL Profiles - available out of the GREAT LAKES AREA, packaged in 2,400 lb pallets (48, 50 lb bags) or 3,000 lb tote bags.  All product sold in pallet quantities only:

  • 1030 Extra Coarse, 4 mil profile
  • 2040 Coarse, 3 mil profile
  • 4080 Medium, 2 mil profile
  • 80/100 Fine, 1 mil profile
  • 100/140 Extra Fine, 0.7 mil profile
  • 325 Mesh, powder only

Sizes available out of Tennessee -  These sizes are 100% "TRUE" grit sizes and are perfect for Dustless Blasters and Soda Based Blasting operations.  This material is considered the "cleanest" media you can purchase because it is manufactured in a facility that produces fine glass powders for filler and extender applications (such as in paints, adhesives).  If you are having contamination problems with your current supplier you should consider switching over to this material.  Shipping in 2800 lb pallets.  56, 50 lb bags.

Safety:   We have sizes that are CARB Approved for outdoor blasting as well as listed on the QPL, but you must tell us if this is a requirement.  We also have some material  that can be blended with lead abatement Blastox, as well as pre-coating compounds like Pretox.  Please email us your requirements so we can make sure we ship you approved material out of approved plants, as necessary.

**  Recommend to use at 90 PSI for best results and increased energy savings (unless you are blasting aluminum or other soft surfaces.) 

** The thinner the abrasive to air mixture, the higher your rate of production will be.  Be stingy - meter the abrasive back until you can no longer see it in the air stream.  This may sound counter-intuitive, but glass blasting is different from heavier abrasives. 

Tips On Blasting With Glass Abrasive:

  • You do NOT want a lot of abrasive in the air stream.  The grains collide with themselves, lose energy, and hit your surface with less impact.
  • Your goal is to not be able to see the abrasive in the air stream.  If you can see it, meter back, as you have too much abrasive going through your hose. 
  • Start by purging your line so it is abrasive free.  Then slowly open the feed until you can see the abrasive in the air stream.  Then slowly close the feed until you can no longer see the abrasive in the air stream.  This is what you want.
  • If you have too little abrasive in the air stream, you will likely hear a high pitched whistling sound.  Start over and this time repeat the process slower so you can see when the abrasive is no longer visible in the air stream.  Be Stingy!  You will achieve better results with a lean supply.
  • Move your nozzle faster than you normally would.  Glass abrasive blasts very fast, very clean.  You will be surprised how light and sharp it is, and how much feathering you get with it. 
  • Blasting hard mil scale will require using a finer grit size, as it cuts more like a knife than a hammer.  This is why it is great for softer, elastomeric coatings that often bounce back heavier abrasives. 
  • Blast at a 90 or 100 psi, or less.  Higher pressure will be counterproductive due to how light glass abrasive is.  You will simply shatter the glass rather than allow it to work for you.
  • You can use a finer size than you would normally use. 
  • Estimate 5 to 6 lbs per sq ft usage.  So a 1,000 sq ft area would require 5,000 to 6,000 lbs of media.
