Plastering & Rendering

Smell of wet plaster

Two years ago we had an old sun room and dining room knocked into one to form a new playroom. The old sun room had internal pebbledash walls which were boarded and plastered over. The ceiling in there was replaced with tiles and velux windows and then also boarded and plastered. We had the ceiling in the old dining room re plastered to provide a consistent finish. Since then we have a strong smell of wet plaster when it rains. It is definitely strongest in humid weather. Today I cannot sit in there it is so strong. The room was decorated by a decorator who used watered down paint initially on the ceilings. The walls were papered to match the dining room and the plaster had dried for a couple of weeks before any decorating began. The are no visible damp patches or signs of water ingress anywhere. The walls feel dry to the touch and there is no paint blistering or flaking. Our builder will not return to look at it - he claims to have no sense of smell. I have read on some forums that modern emulsions to do seal effectively and using a breathable paint is advised? It is a single brick built 1950's house. We have not experienced any problems in any other newly decorated room, but this is the only room that we have had plastering done. Any help/advice would be greatly appreciated.
