Abstract

Efflorescence, also known as lime bloom, may appear as a white deposit covering part or all of the surface of products containing cement. The result of light deposits is the lightening of the surface colour the heavier the deposit the lighter the colour. Except in very severe cases the phenomenon disappears completely when the unit is wet and reappears as it dries out. The phenomenon is temporary and will, with time, disappear as a result of normal weathering. The length of time will depend on many factors such as rainfall, atmospheric pollution etc.
