This technique - Tadelakt - is a mineral finish, rich in pigments, very much like the whitewash coating used for exterior decoration in Europe. Tadelakt is still a very fashionable Parisian interior wall finish. Created with multiple layers then it can then be polished with a pebble and black soap (as in the Maghreb), or with wax and a spatula. The wax finish can be pearly, silver or gold according to the chosen colour, this brings out the richness of the surface. This decoration was created for an Haussmannian apartment in the fashionable 16ème arrondissement of Paris.
