What makes GMA Garnet unique?
GMA Garnet™ is an inert natural mineral that outperforms other abrasives due to its inherent hardness, toughness, density, and angularity. These qualities, when combined with the recommended equipment and air pressure, provide teams with unmatched performance, such as reduced blasting hours, lower abrasive consumption, and excellent control over how much material is removed.
How your abrasive choice impacts your business.
When estimating your abrasive blasting project costs, the abrasive price won’t tell the whole story. Forecast your profitability with an abrasive cost comparison based on independent third-party analysis of abrasive cost, abrasive consumption, blasting hours, disposal costs.
Trevi Fountain regains sparkle after precision cleaning with GMA Garnet
The 18th century Baroque monument was in a critical condition due to microbiological and biological attacks, corrosion from the fountain, rainfalls and wind as well as black encrustations from layers of dust, topsoil and dirt.
“We prefer GMA Fine garnet for its effective performance especially when we had to work with very low operating pressure valves.”
