Solid as a rock

Perhaps the best footing plaster

As a mineral cement plaster aerodurit® ZEP2040 offers versatile application possibilities and fulfils the highest demands. The use of high-quality cement, tempered with the proven aerodurit® additives gives aerodurit® ZEP2040 high water vapour diffusion resistance, increased adhesion, very high impact resistance and excellent salt resistance. These properties make it the perfect plaster in damp areas, e.g. for footing areas, city walls or basement renovation without expensive drying measures.

Special building materials open to diffusion

With the diffusivity (sealed and permeable at the same time) of our microporous technology, we solve problems with moisture, dampness and mould in the long term. Due to this natural and highly efficient mode of action, aerodurit® EP2010/ZEP2040 is used at the latest when conventional systems fail and the demand for healthy, ecologically safe living becomes clear.


During mixing, a special pore system is created in the plaster mortar of our dehumidifying plasters, which helps to dry out damp walls in a very short time. Due to the physical principle of capillarity, the damp wall is literally »sucked dry«. The removal of moisture and rapid evaporation result in extremely fast drying of the wall. Salts stored in the wall thus crystallise once inside the masonry and do not cause any damage.

If there is a further rise in moisture, fine particles carried along in the water contribute to the natural narrowing of these ascending paths through sintering. This creates a permanent, natural barrier and prevents renewed moisture penetration. The diffusivity and functionality of the pore system are permanently preserved. Additional measures such as sawing walls, placing metal sheets and the use of chemical substances, etc. become unnecessary.
