Greengrit Crushed Glass

Manufactured by Opta Waterdown Inc.
Brand: Greengrit

Greengrit is a crushed glass grit made from 100% post-consumer recycled glass. It is crushed, cleaned, sized, and packaged to provide the ideal blast media for many applications. Its angular shape allows Greengrit to cut through rust, paint, and oil, and yet it is lightweight enough to create a low profile on the surface.
