Lime-wash is a popular surface treatment for masonry due to its technical properties, such as its ability to protect the masonry in a perfect way, its strength, and its ease of maintenance. It has been used for over 1000 years and is particularly suitable for weak and deteriorated materials on old buildings.

Lime-wash is made by burning natural limestone (calcium carbonate CaCO3) in a kiln at 900-1000 Celsius. After burning, the “quicklime” (CaO) is slaked with water to produce lime putty (Calcium hydroxide Ca(OH)). The putty is then sieved to remove any unslaked lumps or extraneous materials and matures in a pit. This wet slaked lime putty can be mixed with sand of different roughness/size of corns to produce lime mortar or plaster, which is the same but used differently.

Lime colors are usually white, but certain colours can be added to create colored lime-wash or lime-colours. The hardening of lime occurs through carbonation, a chemical process involving atmospheric carbon dioxide and water as an important solvent. This process forms calcium carbonate, the original limestone, firmly integrated in building construction.

Despite its advantages, lime-wash has limitations and disadvantages, such as its rigid demands on weather, temperature, and moisture conditions, the need for experienced craftsmanship, and the need for a perfect, un-defect, dry, and cement-less ground.
