If you want to make a concrete wall yourself, you should already have some experience working with concrete. Vertical structures that are to be cast require a solid foundation and strong casing. Since a concrete wall is usually to have a very smooth surface, you must work with formwork oil or release agent.
Real concrete or imitation plaster
Anyone who wants to make a concrete wall himself, which is later to be removed again, because it is for example a rented apartment, can paste a non-woven wallpaper as a sacrificial wallpaper under the plaster or visual screed. Together with her, the structure of the concrete imitation can be completely removed.
