The high bulk density and Mohs hardness of Hard Rock Garnet is ideal for quickly cutting through thick coatings and producing deeper surface profiles. Being a mined mineral, Hard Rock Garnet naturally has low chloride levels, reducing the risk of surface contamination. Hard Rock Garnet is non-metalic and will not leave a residue to interfere with coatings, and is virtually free of embedment.
