My husband painted our bedroom with water-based paint the other day. He kept the door closed at all time but I don’t think he had the windows open. I was in the room a few times to collect things but only for very short periods of time. We have since had the windows open and kept the door closed, and have slept in another room, but I am still worried about exposure to the fumes. Any advice/reassurance would be great as I’m feeling quite stressed about this.
