What is Efflorescence and How to Cure it | DIY Doctor
Efflorescence is a type of white chalky deposit found on brick, masonry, concrete and plastered surfaces. It is formed when natural salts and minerals in these materials dissolve in water present in the material, the water travels to the surface, evaporates and the mineral deposits are left as white chalky stains.
