<p>This article discusses the issue of renovation of buildings having damp and salted walls. The results of conservation research on the walls of two historical buildings from the beginning of the 20th century are presented. It was determined that the walls of the buildings are burdened with moisture and salts. The use of traditional cement and limestone plaster for renovation of such walls, due to their low diffusivity, is a temporary and short-term solution. A suitable material is a renovation plaster, which should be selected depending on the properties of the wall. Various approaches to the renovation of these two buildings were presented. Where moisture was caused by capillary rise, the moisture barrier was first restored and a system of renovation plasters consisting of rough coat, undercoat plaster, hydrophobic plaster and paint coating was used. In the second case, due to only a partial replacement of the plasters, after protection of the facade against rainwater, the plasters will be supplemented with renovation rough coat and hydrophobic renovation plaster. Before applying the paint coating, the entire surface will be covered with a renovating lime putty.</p>
