Renovation of buildings having damp and salted walls – case analyses

Keywords: renovation plasters, salts in walls, moisture in walls
Abstract:

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.
