ABSTRACT:
A process for removing coatings from hard surfaces includes blasting the surfaces with a free-flowing particulate blast media entrained in a pressurized fluid, the blast media containing a major amount of relatively soft granular abrasive particles which have a Mohs hardness of less than 4.0 and a minor amount of free-flowing, separate relatively hard granular abrasive particles which have a hardness of greater than 5.0 on the Mohs scale, the granular abrasives having a particle size of from about 10 to about 2000 microns and being devoid of crystalline silica material.
