Had front room plastered today, and left the windows open for a good 5 hours after it was finished to let the fumes escape. Been sitting watching a film for the past 2 and a half hours, I closed the windows before I sat down and drew the curtains but noticed by the end of the film all the windows in that room have heavy condensation on them (can barely see out of them), so I've opened the windows again. Is it because there's still fumes from the plaster? Is it safe to be sitting in the room without any ventilation?
