Tadelakt

Tadelakt is a waterproof plaster surface used in Moroccan architecture to make baths, sinks, water vessels, interior and exterior walls, ceilings, roofs, and even floors. It is made from lime plaster, which is rammed, polished, and treated with soap to make it waterproof and shiny. Its traditional application is seen in Marrakesh, Morocco, to coat the walls of palaces, hams, and bathrooms.

History

The term tadelakt is Arabic (tadla:kt), meaning to 'rub in' or 'caress'. It has been used in Morocco for over 2000 years, originally in the palaces of Marrakesh. The technique was passed down from generation to generation by master craftsmen, and it is still used in contemporary construction.

Composition and Application

Tadelakt is composed of lime plaster, which is a mixture of quicklime and water. The plaster is applied in several layers, each of which is polished with a river stone and treated with olive soap to make it waterproof. The final effect is a smooth, shiny surface that is both beautiful and durable.

The application of tadelakt requires great skill and is considered an art form. The process begins with the preparation of the lime plaster. This involves slaking the quicklime in water for a period of up to three months. The plaster is then applied to the surface in several layers, using a traditional Moroccan trowel. Each layer is left to dry before the next is applied. Once the final layer is applied, the surface is polished with a river stone and then treated with olive soap to create a waterproof seal.

Uses

Tadelakt has a wide range of uses in both interior and exterior settings. It is commonly used in Moroccan architecture to coat the walls of palaces, hams, and bathrooms. It is also used to create decorative objects such as water vessels and bowls. In contemporary construction, tadelakt is often used in the creation of baths and sinks, as well as for wall and ceiling finishes.

Maintenance

Tadelakt is a durable material, but it does require some maintenance to keep it looking its best. This typically involves the application of a fresh coat of olive soap every few years to maintain its waterproof properties.
