(Arabic: قضاض, qadâd, kʉðað) or qudad also known as Tadelakt in the modern era: is a waterproof plaster surface, made of a lime plaster treated with slaked lime and oils and fats. The technique is over a thousand years old, with the remains of this early plaster still seen on the standing sluices of the ancient era.
Volcanic ash, pumice, scoria (Arabic: شاش), in the Yemeni dialect, or other crushed volcanic aggregate are often used as pozzolanicagents, reminiscent of ancient Roman lime plaster which incorporated volcanic aggregate.
In Sana'a of the early 20th-century, Tadelakt-plaster was used to line pools, reservoirs, and cesspits, and to make them impermeable. Often its use extended unto the main kitchen room and to gutters and sinks, wherever water was likely to be used extensively. The walls of store-rooms where grain was kept and which required being impervious to water were also frequently painted-over with Tadelakt, and which gave to the rooms an appearance of being painted with oil-paint. Carl Rathjens who visited Yemen in the first-half of the 20th-century mentions seeing in Sana'a "the houses of well-to-do people" where the entrance halls were often painted with Tadelakt up to a certain height. The interior walls of public baths were sometimes brick, sometimes stone. they were protected with a thick layer of hard gypsum plaster which were then oil-painted.
In Islamic architecture, different consistencies of Tadelakt were made for different usages: domes, flat ceilings, vertical walls and decorations in the geometric interlaces.
