Crushed Glass for Sandblasting
Chemically inert, non-reactive. Made from 100% recycled glass. Less than 1% free silica. Available in 50 lb bags and 3000 lb super sacks.
Crushed glass is used as an abrasive sandblasting media in a variety of industries such as: dustless wet blasting, slurry blasting, blasting ship hulls, concrete restoration, cleaning tanks or pipelines, graffiti removal, and auto restoration.
Why Use Crushed Glass as a Sandblasting Abrasive?
- Made from 100% recycled glass.
- SSPC AB-1 Class A, MIL-A-22262B(SH) approved.
- Contains less than 1% free silica.
- QPL and CARB approved (in selected plants).
- 31% less dust generated and 97% improved cleaning rate versus coal slag.
- Crushed glass can replace OSHA-regulated silica sand for abrasive blasting on construction sites.
- Allows contractors to use a CARB certified, chemically stable, inert media to remove paint and powder coating.
- When properly used, crushed glass is mild enough to use around environmentally sensitive areas and delicate jobs.
- Suitable for restoration of wood, and thin metal surfaces.
- Works well in wet blasting, dustless blasting, and slurry blasting equipment. Using a rust inhibitor is recommended if you are abrasive blasting steel.
Available in 50 bags and 3000 lb super sacks.
What Grades of Crushed Glass Are Available?
You can buy crushed glass abrasives from our warehouse in three sizes:
- Fine: 70/100 mesh grit
- Medium-Fine: 40/70 mesh grit
- Medium-Coarse: 20/40 mesh grit
Applications for Crushed Glass Abrasive
Fine (70/100): Perfect for blasting aluminum, chrome, brick, concrete, and wood. Applications may include graffiti removal, dustless blasting, paint removal, aged wood restoration.
Medium-Fine (40/70): Surfaces you can blast include slate, marble, fiberglass, stone, copper, brass, iron, brick, granite, or concrete. Ideal for mill scale removal, building restoration, automotive, general cleaning or stripping.
Medium-Coarse (20/40): Uses include bridges, tanks, steel construction, metal fabrication, or precast concrete where a deeper profile is preferable.
Practicality of Using Crushed Glass For Sandblasting
Crushed glass is primarily used as an abrasive media for outdoor dry blasting. Many suppliers use recycled beer and wine bottles to create crushed glass abrasive media. Compared to other abrasive blasting media, such as aluminum oxide, crushed glass is less expensive, but has different applications. Crushed glass is not usually recycled, like other sandblasting media might be.
Similar to aluminum oxide and garnet, crushed glass leaves an angular profile on the blasting surface. Peaks and valleys are left on the substrate, creating an anchor pattern for powder coating, painting, or other coatings.
Powder coating sits above the profile at about 10mm, while the angular profile etched by the abrasive sits at about 3mm. This gives the powder coating or paint something to cling onto, making the surface stronger. Crushed glass is somewhere between a 5 and 6 on the Mohs hardness scale.
Crushed glass is also ideal for the removal of surface coatings such as rust, paint and scale from a wide variety of substrates, like aluminum, stainless steel, concrete, brick, and wood.
