Tadelakt Tutorial - How to make it (Complete step-by-step)
Tadelakt is a Moroccan coating made from lime, an aggregate, and a vegetable soap. Lime is a limestone that is turned into powder through calcination and returns to rock form during the carbonation process, where it reacts with oxygen.

Tadelakt's main characteristics are its polishing and the use of soap.
Polishing can be done with a steel trowel (although if you overdo it, it can darken) or with a hard, polished stone. This closes the surface pores and removes trapped air when stretching the mass.
The soap (traditionally olive oil or black soap), which can be any neutral, vegetable-based soap, reacts with the calcium and produces calcium stearate, resulting in a water-repellent surface.
The tadelakt in the video was applied in two layers, although some artisans create it with more. You just need to make it very smooth before you even start polishing with the stone.

The mix used in this video was:
1 part quicklime (hydrated for 2 weeks);
1 part washed and sifted sand;
1/2 part marble dust.
You can also use crushed stone dust.
It is essential that all components are very well sifted.
The pigment used was powdered iron oxide, which is characterized as natural and non-organic, being a synthetic iron oxide.
