SPALLING:

Spalling is recognized when pieces of masonry or brick, split and flake off. Minute cracks in concrete, brick, or mortar joints if not filled properly with paint will allow moisture to enter. In winter this moisture freezes and swells, splitting off small pieces of masonry. Paint improperly applied over a porous surface may not close these cracks and crevices. The surface, due to spalling, gradually erodes, eventually breaking down the surface of the masonry. The use of an acrylic surface conditioner and proper priming will help overcome this condition.
