What is Efflorescence?
Efflorescence is a natural phenomenon. Water in the form of rain, condensation and dew penetrates the pores of the concrete and partially dissolves the lime. The solution diffuses to the surface of the concrete and the water evaporates, leaving a white lime haze which is not readily soluble.
*Efflorescence is a crystaline deposit on surfaces of masonry, stucco or concrete. It is whitish in appearance, and is sometimes referred to as “whiskers”.
