![]() Long-term maintenance of tadelakt requires regularly re-sealing the surface with a soap solution in the case of qadad roofs, this was traditionally done every few years. lastly, an olive-oil soap solution is used to seal the plaster.it is mechanically polished using stones or abrasives harder than the plaster, providing a smooth, sometimes shiny, finish.before the plaster sets, a flat, smooth, hard stone is used to compress the plaster, then a plastic trowel used for the final polish.the plaster is applied in one thick coat with a wooden float, and smoothed with the same.plaster powder is mixed with water for 12 to 15 hours prior to the addition of pigment.In Morocco, the traditional application technique: Traditional application includes polishing with a river stone and treatment with oleic acid, in the form of olive oil soap, to lend it its final appearance and water resistance. Mixing plaster powder with water and yellow pigment to make tadelakt in Riad Dar Rita, Ouarzazate, Morocco They are familiar, in areas with calcium-rich ("hard") water, as deposits in bathtubs, sinks, and showers when soap is mixed with the water's dissolved calcium carbonate/lime, calcium soaps form.Ģ C 17H 35COO −Na + + Ca 2+ → (C 17H 35COO) 2Ca + 2 Na + Techniques Calcium soaps are insoluble in water, and fairly hard. The soap chemically reacts with the lime plaster, forming lime (calcium) soaps. natural soap (often "black" or olive oil soap) to speed carbonation of the surface and impart water-resistance.in some cases, marble or limestone sand (but not other aggregates).The basic constituents of tadelakt plaster are: ![]() Tadelakt is thought to have evolved from qadad, a similar plaster used in Yemen for millennia that is treated with calcium hydroxide and oils and fats instead of soaps. The term tadelakt, meaning "to rub in", is an Amazighified expression from the Arabic word تدليك tadlīk, meaning "to rub or massage." Pigment can be added to give it any colour, but deep red is traditional. Since it is applied as a paste, tadelakt has a soft, undulating character, it can form curves, and it is seamless. Tadelakt is labour-intensive to install, but durable. It is made from lime plaster, which is rammed, polished, and treated with soap to make it waterproof and water-repellent. Also, various lighting conditions affect the tone of the surface differently each time, representing a unique tactile "handwriting" masterpiece.Tadelakt ( Moroccan Arabic: تدلاكت, romanized: tadla:kt) is a waterproof plaster surface used in Moroccan architecture to make baths, sinks, water vessels, interior and exterior walls, ceilings, roofs, and floors. The look depends on the surface treatment - the place of stronger compression results in a darker, deeper hue. The surface colour doesn' t stay as constant as with other rendering materials. The way in which it is created with a small stone leaves the surface slightly wavy, alive and naturally glossy. ![]() Tadelakt is indeed something very original and imperceptible. Particularly impressive is the feel of the surface to the touch. The glow of tadelakt surface is charming and attractive. It is used also in sinks, baths and even as a coating of the tables, creating special and unique surfaces. Nowadays, tadelakt is often used to replace bathroom tiles on walls and floors. This type of polishing has a very high surface density, corresponding to modern high-quality concrete surfaces.1 It was burned, extinguished and then used directly as plaster. The nature offered there in essence an already prepared finishing material. Historically, the Moroccan tadelakt was used only the city of Marrakesh. A traditional Moroccan tadelakt (pronounced tadla:kt) plaster is used for water resistant surfaces as finishing and is gaining popularity in both Europe and Australia.
