Is efflorescence a cosmetic issue only?

The statement that efflorescence is a cosmetic issue only is false. Efflorescence occurs when soluble salts within water migrate to the surface of concrete, masonry, or stucco as moisture evaporates. While it might present a surface-level appearance issue, it can indicate underlying problems such as excessive moisture, water infiltration, or poor drainage.

In some cases, efflorescence can lead to more significant structural concerns if moisture continues to penetrate materials, which could compromise their integrity over time. Therefore, addressing the cause of efflorescence is crucial, rather than viewing it solely as a cosmetic concern. This understanding emphasizes the importance of moisture management in building materials, particularly in preventing potential long-term damage and ensuring the health of the structure.
