Question

Meaning of efflorescence

Answer 1

Efflorescence is the process where salts and minerals in building materials such as concrete, brick, or plaster dissolve in water and then migrate to the surface as the water evaporates, leaving a white or powdery residue behind. This often occurs in older buildings or structures that are exposed to water or moisture over time. Efflorescence can be unsightly and may indicate underlying issues with the structure's water management.
