'SWEATING' of Newly Applied Plaster - Problem?

[seafuryfan]

A reputable plaster who has done good work for us in the past has recently finished plastering a bedroom. The interior walls have dried out fine, and I was warned that the exterior (2 1/2" cavity, recently bead insulated) walls would take longer to dry.

2 weeks after plastering, the two exterior walls are 'sweating' in the vicinity of the windows, mainly above them. The plaster still looks obviously not dried out.

I have to admit the room has not had ventilation (open windows) due to the recent cold weather, and condensation has been prevelant on the windows. I have today installed a portable radiator, hoping this will do the trick.

Am I doing the right thing, ladies and gents? Should I be concerend about anything or just let it continue to dry out? And should I avoid painting it in the meantime? Any advice appreciated.

open a window and shut the doors.

Deff avoid painting for a while..its ok what you are doing by introducing heat.....but be careful......dont assume it all dry just because the plaster has appeared to turn pale.

Take the heater away for a couple of days and see if more moisture comes to the surface.

It could be that you have only dired the top 1/2 mm......Consider a de-humidifier.

Thank you both for your replies. I'll crack on as advised and for anyone interested will further post later on, with how it turns out.
