An encrustation of soluble salts, commonly white, deposited on the surface of stone, brick, plaster, or mortar; usually caused by free alkalies leached from mortar or adjacent concrete as moisture moves through it
A deposit or encrustation of soluble salts, generally white and most commonly consisting of calcium sulfate, that may form on the surface of stone, brick, concrete, or mortar when moisture moves through and evaporates on the masonry Often caused by free alkalies leached from mortar, grout, adjacent concrete, or in clays
A powdery stain, usually white, on the surface of or between masonry units It is caused by the leaching of soluble salts to the surface

A white powdery substance that can form on new block, brick, or stucco finishes It is composed of water soluble salts that are present in masonry materials and that rise to the surface via water evaporation
Whitish powder (salt deposits) that sometimes appears on masonry surfaces; it is carried to the surface by moisture
An encrustation of soluble salts, commonly white, deposited on the surface of coatings, stone, brick, plaster, or mortar; usually caused by salts or free alkalies leached from mortar or adjacent concrete as moisture moves through it
