Hi - I wonder if someone can give me a steer as I'm not sure what to do.
I have a new build, in my garden, which is timber with a flat fibreglass roof. The floor was finished (ie the top level concrete) about 4 weeks ago and that is now virtually dry, and the plaster was finished about 3 weeks ago. The room has a ledge where the timber sits on cement blocks, so there is a fair bit going on behind the walls which may impact on drying - for instance, the metal brackets where the timber frame posts sits slightly stuck out so the plasterboard used had insulation attached and this was scraped away by the brackets to fit flush to the wood, if you see what I mean. Maybe this impacts on where moisture ends up, I don't know (eg does it tend o be worse by the metal posts?). I also note that the timber won't have been completely dry when installed, as it's been crappy weather!
Anyway, the plaster dried reasonably well but if anything it's got worse recently in certain areas (edges and around one light fitting) and certainly hasn't got better for the last 10 days or so. I wonder if this is coming from condensation on the outside of the plaster, as I'm sure that the roof etc is all sealed. If so, then I wonder how the plaster edges will ever dry in the winter?
Some pics are attached. I just don't know what I can do to speed this up, if anything.
I have a domestic dehumidifier running, but I'm not sure what to do about ventilation - perhaps I just keep everything closed as much as possible and try to retain a sensible temperature?
