Paint is toxic, even latex. Don`t paint, or paint and have her move
out. How long? I dont know contact a doctor and paint companies, but I
would say with open fresh air, not AC and a closed house one or two
weeks. with a closed house maybe a month. I used to paint for a living,
even latex makes you sick. Just read a paint can label, it has warnings
about breathing vapor, sure it dries fast, but as it cures it releases
chemicals and with modern chemistry and ever improving paints you have
no idea what is in paint.
