Lime plaster is a type of plaster composed of sand, water, and lime, usually non-hydraulic hydrated lime (also known as slaked lime, high calcium lime or air lime). Ancient lime plaster often contained horse hair for reinforcement and pozzolan additives to reduce the working time.
Lime plastering is composed of lime, sand, hair and water in proportions varying according to the nature of the work to be done.

Pure lime is pure white and can be used for whitewash, plaster, and mortar. Pure lime is soluble in water containing carbonic acid, a natural, weak acid which is a solution of carbon dioxide in water and acid rain so it will slowly wash away, but this characteristic also produces autogenous or self-healing process where the dissolved lime can ...
Very early in the history of Greek architecture we find the use of plaster of a fine white lime stucco, such has been found at Mycenae. The art had reached perfection in Greece more than five centuries before Christ, and plaster was frequently used to cover temples externally and internally, in some cases even where the building was of marble.
Black lentil paste, molasses, brick dust, mustard meal, and limestone powder were used in the cementing and plastering mixture. Lime-plaster (Bajra), a mixture of molasses, black pulse, jute, brick dust and lime, was the main ingredient for plaster as it had been for centuries in Nepal, primarily as it had good resistance against humidity.
Lime comes from Old English lim ('sticky substance, birdlime, mortar, cement, gluten'), and is related to Latin limus ('slime, mud, mire'), and linere ('to smear').
