Brick Cleaning Systems - Sandblast Cleaning - Removing Paint
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.
Sandblast operators can be compared with other construction tradesmen: some are artisans and others are incompetent. However, with a qualified operator, proper specifications and good job inspection, sandblast cleaning is as good as any other system and is sometimes superior in many ways.
