stucco

Durable plaster finish for exterior walls, composed of sand and lime. In the 18th and 19th centuries stucco was used extensively to add dignity to brick buildings, by giving the illusion that they were built of stone. The stucco would be moulded, coursed, or coloured to imitate ashlar masonry. John Nash used stucco to create the illusory stone palaces that surround Regents Park, London (begun 1811).
