When you are painting inside your home, vent the site as you paint, and keep it ventilated after you paint.
Never paint with closed windows.
It could be deadly. Have both a portable air conditioner and air purifier. If run at the same time, with a few windows open, they will help clear the air of all the paint fumes. It can make the difference between having to leave your home for 24 hours or not; you won’t have to leave at all if you spread it out and do one room at a time. With a portable air conditioner and air purifier you can clear the poor air quality created by the paint fumes in one hour. Without these, and just using the windows, it would take many more hours and you would most likely have to leave the home for the day – maybe even two days. This is frustrating. But what isn’t frustrating – with this equipment, you can speed things up and have that poor air quality removed much faster! I tried it out and it worked perfectly the last time I did some indoor painting in our home.
