garnet sand 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.
