AbstractThe two general conditions necessary to produce efflorescence in masonry walls are (a) presence of soluble satls in the wall materials and (b) moisture to carry these salts towards or onto the surface of the wall. No simple method, capable of general application, has been devised to limit the soluble salt content in masonry materials. Hardly any masonry material is exempt from the possibility of containing sufficient soluble salts to contribute to the development of noticeable efflorescence if moisture should penetrate the wall. Moisture penetration of the wall, and with it, efflorescence, may be almost completely prevented by proper design, construction, and maintenance of the building.
