Schalsteinmauern can also be erected by amateurs without any problems. The concrete filling makes them stable and durable. However, when doing the final plastering, you need to pay attention to a few important points, which we would like to discuss in more detail in this article.
Plastering formwork stones must be done cleanly and logically
What are scarf stones?
Classic hollow blocks, such as those used to build a garden wall, are made of concrete or lightweight concrete. With these, even amateurs can build a very functional wall. They have a hollow core of air chambers that is open at the top and bottom and is filled with concrete.
The processing is very simple: The stones are placed next to each other with the tongue and groove system. If the free-standing garden wall exceeds a certain height, you should insert reinforcing bars for better stability. The cavities in the finished wall are filled with flow concrete from above. Finally, cover the last row of stones with wall cover plates.
Be sure to let the concrete harden for a sufficient amount of time before plastering, as the material dries slowly due to the poor capillary system.
How is plastered?
Since cement plaster does not adhere well to concrete blocks due to its lack of absorbency, you should prepare the garden wall accordingly. Before applying the plaster, this must be completely free of residues such as dust and release agents.

- First apply the primer. This ensures a secure connection between the concrete blocks and the applied plaster.
- Mix the reinforcement plaster exactly according to the manufacturer's instructions.
- Reinforce the surface with reinforcement mortar and the appropriate fabric.
- Smooth the garden wall with the float and let everything dry thoroughly.
- You can then apply a decorative structural plaster.
- If you wish, you can coat the wall with a coat of paint of your choice.
tips
A resistant, mineral silicate plaster is highly recommended. This has the advantage that moss, lichen, algae and fungi can no longer settle on the garden wall. This special plaster is available in an attractive range of colours. In addition, the material can simply be painted over.
