ABSTRACT:
A method for blast cleaning a solid surface using an abrasive composition of calcium carbonate, wherein the abrasive-blasting operation uses blasting apparatus including a blasting pot, a blasting hose and spray nozzle connected to the blasting pot, an air compressor and compressor air lines connected to the blasting pot, and blasting hose and spray nozzle, comprising the steps include filling the blasting pot with an abrasive composition of a coarse, medium, or fine grade of calcium carbonate, selecting a blasting spray nozzle having a specific size, adjusting the media flow valve connected to the blasting pot to set a specific blasting flow rate, setting the air pressure on the compressor air line connected to the spray nozzle, setting the air volume flow rate on the compressor air line, holding the spray nozzle a distance of 6" to 24" away from the surface to be cleaned, and moving said spray nozzle across the surface to be cleaned and wherein the above sequence of steps may be varied.
