ABSTRACT:
A wet blasting media involving fine particles having a mean diameter less than 0.5 mm, and a specific gravity of at least 1.5. The particles are formed by glass beads having an irregular plastics resin mass therearound, such as a polyacetyl or polycarbonate resin. The resin has a specific gravity of 1.3 or greater. The particles readily uniformly mix with water to permit uniform blasting of articles, and at the same time the glass beads provide the particles with the desired density but do not damage the surface of the articles being blasted.
