Efflorescence
Efflorescence is a common issue in masonry work that appears as white, powdery deposits on brick, concrete, or stone surfaces. It happens when water moving through masonry materials brings natural salts to the surface. While it's mostly a cosmetic issue, its presence on a resume shows that a masonry professional understands quality control and problem-solving in construction. It's like detecting and fixing water stains in a building - it demonstrates attention to detail and knowledge of building maintenance. When you see this term, think of it as showing experience with quality inspection and problem diagnosis in masonry work.
