Glass Bead Blasting vs. Garnet Sand Blasting
Both glass and garnet blasting media are known for their durability and environmental friendliness. Neither of them produces as much dust as coal or silica sand. Glass tends to be somewhat less expensive as it is made from recycled materials, but it is not quite as hard as garnet. Both are good options for concrete, aluminum and fiberglass substrates which need to be prepared for thick outer coatings. Of the two, garnet tends to have a longer lifespan due to its hardness and has extremely high density for faster cutting.
