Garnet Sand for Sandblasting is from the naturally Almandine mined deposit consisting of extraordinarily aggressive, hard, and sharp grains. The harder species of abrasive garnet are used for abrasive. Garnet has a hardness on the Mohs scale of about 7.5 to 8.0. Once extracted, garnet sand is washed, processed, and screened to the necessary abrasive grade for abrasive media. Garnet sand for sandblasting can be recycled and used as an economical alternative to Aluminium Oxide Girt, Chilled Iron, or Steel Grit shot. Garnet sand for sandblasting generally creates less dust than other abrasive sand.
Garnet Sand for Sandblasting is the Optimum Abrasive for Most Applications.
Clean – Garnet abrasive sand produces less dust than other expendable abrasives, making it ideal for use in tanks and other confined spaces.
Cost-Effective – Garnet sand abrasive lasts a long time. Garnet Abrasive is reusable and can be re-used several times under the right conditions.
Optimum Surface Profile – Garnet abrasive creates a superior surface for adhesion coating.
Environmentally Friendly – Abrasive Garnet Sand is inert and non-toxic, making it safe for use around water bodies. It is also very easy to clean, while its durability reduces the generation of dust.
