What Is Efflorescence?
- It’s a chalky white powder sometimes found on porous materials like concrete and brick. It consists of salt deposits that remain on the surface of these materials when water – mostly groundwater but sometimes also rain water – evaporates.
- Unlike mold, it’s not harmful to the materials on which it’s found and it won’t make you sick. It is mostly a cosmetic issue, but it can also sometimes indicate excessive moisture, which can be problematic. Excessive moisture can lead to mold growth and can also damage building materials.
