Glass Bead blasting is the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface. It is used to clean calcium deposits from pool tiles or any other surfaces, and removes embedded fungus and brighten grout color. It is also used in auto body work to remove paint. Glass Beads are solid glass spheres. They are manufactured from high grade soda-lime silica glass containing SiO2 around 70%. They are free from free lead, iron and silica.
