Advantages of Garnet for Blast Cleaning
- Wide range of grades and composition available for different jobs and profiles
- Superior surface profile – garnet grains create a uniform profile virtually free of embedment, providing an excellent surface for coating adhesion
- Cost–effective - highly effective, low consumption
- Non-toxic – inert and natural, crystalline silica levels are less than 1%
- Recyclable up to 5 times
- Low dust levels – improved operator visibility
- Easy cleanup
- Non-reactant – will not interfere with your coatings
- Non-porous – will not draw moisture
