This decorative plaster originated from the Marrakech region of Morocco and was first used in the 11th century to waterproof the royal Berber water tanks.  It has a refined, smooth, and polished surface similar to that of a natural stone and has a satin sheen.

Tadelakt is very durable if cared for correctly.  Avoid using strong chemicals like bleach since this harsh cleaner will destroy the delicate limestone surface.

Traditional Moroccan Tadelakt colors are inspired by the spectacular hues of Morocco, which include glossy browns and yellow ochres, scarlet, cool cobalt, and saffron yellows.
