The drying time of aerodurit building materials always depends on the degree of moisture penetration, type of masonry and environmental conditions. Of course, the type of building material also plays a role (base and finishing plaster, screed, paint etc.). Detailed information can be found in the respective technical data sheets (Downloads). As a rule of thumb for plastering, a 36 cm thick brick wall must dry out for about 4 weeks under normal weather conditions. After that, the paint can usually be applied. In the case of frost, this period is extended by the number of days of frost.
