The craft of Tadelakt is a Moroccan tradition, using lime from the Marrakech Plateau, where the original Tadelakt lime can be found. This is also where the word “tadelakt” comes from, and it means “to rub in” as olive soap is rubbed in to the lime. This results in a hydrophobic lime plaster that can be used on both the interior and exterior of buildings. It is the traditional coating of the palaces, hammams and bathrooms of the riads in Morocco. Traditional application includes polishing with river stone and treatment with oleic acid in the form of olive oil soap to acquire its final appearance and water resistance. Tadelakt has a luxurious, soft, undulating character, and has been employed for baths, showers, and basins.
