Dry sandblast cleaning is a relatively new method of cleaning block machine newly built masonry, although the system has been used for many years in masonry restoration work.

Many architect/engineers prefer sandblast cleaning over conventional wet (acid) cleaning because of possible adverse acid reactions with certain types of brick. Other designers are reluctant to permit sandblast cleaning from fear the blasting will erode the face of the brick and mortar joints.

Basically, sandblast cleaning involves the following equipment: Portable air compressor, blasting tank, blasting nozzle, operators’ protective clothing and hood.
