Our holiday home in Greece is of reinforced concrete construction.
To eliminate mould growth on the cold bathroom ceiling, we had polystyrene insulation fitted to it with plasterboard covering. The job was neatly done and very effective at eliminating mould.
However, about a year later, a large portion of the (about 1mm thick) plaster skim near the centre of the ceiling has come crashing down.
What advice can plastering experts offer to rectify this and hopefully prevent its recurrence, please? I'm not bothered about aesthetics.
