Efflorescence and Masonry

Efflorescence is a crystalline deposit of water-soluble salts (usually white) on the surface of masonry. All masonry materials are susceptible to efflorescence. In a chemical analysis, water-soluble salts consisting of only a few tenths of one percent is sufficient to cause efflorescence on a masonry surface. The amount and character of salts of the deposits can vary widely, depending the nature of the soluble materials and the atmospheric conditions.
