In contrast to aerodurit special restoration plasters such as aerodurit EP2010 or aerodurit ZEP2040, other brands are mostly non-hydrophobic (“pore hydrophobic”). The function is similar to a barrier plaster; the restoration plaster can only store a limited amount of salts and moisture. If the absorption capacity is exhausted, the crystallisation pressure in the masonry often “blows up” the plaster again. You therefore have the same problem as before the renovation: the old plaster has to be removed again, which can damage the masonry and weaken its stability, as well as incur further costs. Non-hydrophobic aerodurit special restoration plasters do not “seal”, but transport moisture by capillary action generated by the microprene structure. Thanks to our pore system, embedded salts crystallise once within the masonry and do not cause any further damage. The result: No salt efflorescence on the surface. Diffusivity is the aerodurit solution – sealed and permeable at the same time. Let your walls breathe!
