I recently bought out three walls with plasterboard and plastered them. This was yesterday 12.9.18 and I wasn’t told to leave any form of ventilation in the room so this morning when I entered the room there was condensation on the windows. I’ve opened the door and windows and it cleared. I just shut my door an hour ago and popped in there and it’s building up again (the condensation) I can’t leave my balcony door open all night and we don’t have any nice weather really. What can I do and is this normal? The plaster still looks fresh, only in small areas it looks like it’s changing colour (drying) I’m a little worried so any advise or direction would really help.
Thank you
