Two years ago I covered the walls of the room with drywall. Started noticing signs of dampness, lagging wallpaper, black traces of mold. When I opened the sheet, the plasterboard found abundant moisture on the wall. The old plaster is completely wet, on the profiles below hanging water droplets. What is it – it is possible to sweat and how to deal with it now? The house is old, one-storey, 60 cm thick stone wall. Behind the wall is another apartment.
