Expanded definition

Tadelakt generally refers to any lime plaster applied according to the principles and techniques of Moroccan tadelakt, but using the lime bodies available in places other than Marrakech.

Defining Materials

The basic characteristics of a tadelakt plaster are these:
  1. It is a lime plaster. It does not include Portland cement.
  2. It may include fine marble or limestone sand, but not other aggregates.
  3. It has been compressed when plastic, eliminating all voids.
  4. It has been mechanically polished, using stones or abrasives that are harder than the plaster finish, to provide a smooth, sometimes shiny, finish.
  5. It has been treated with a natural soap (often "black" or olive oil soap) to speed carbonation of the surface and render the surface more water-resistant.

Defining techniques

Basically the plaster powder has to be blended with water for 12 to 15 hours prior of the pigment mix. The walls where the plaster paste will be applied are prepared with cement. A simple machine then spits the plaster to the wall. After the first paste coat on the wall, there are two smoothing techniques, one made with a normal wooden shovel, and afterward one made with a small, smooth stone that eliminates surface imperfections.
