3. Blend with an immersion blender for about a minute. Mix thoroughly so that the mixture becomes smooth.
4. If desired, let it soak for about 12–24 hours. Soaking is an optional step. It can deepen the shade. Keep the mixture in a cold place.
5. Prepare the wallpaper paste according to the package instructions. Check the water and paste quantities for your specific package size.
6. Add the paste to the clay mixture and mix thoroughly with an immersion blender.
7. Perform a test brush stroke. A suitable paint has the consistency of milk-like soured milk. If the paint is too thick, add a little water and mix again.
The paint is then ready for use. Keep the finished paint in a cold place and stir it also during painting.
