When you are doing any kind of indoor painting, it is constantly important to have nice ventilation within the house.
The nice way to do this is to do all painting while I was in the time of the year when it is either chilly or just standard temperatures. You never want to do it in the warm Summer time weeks of the year. Because you will need to have windows opened plus have fans blowing. You would not want to be running your central a/c while having windows open because this will make your energy bills high. Even if doing it only for a week while you paint the house. The best thing to do is to also have some kind of portable air cleaner while you have the windows open. By having a portable air cleaner running it helps get rid of the toxins in the air from the paint while the cross breeze flows from the windows being open from all ends. I have 4 portable air cleaners I had purchased when I did a major paint task inside our beach house a few years back. They easily helped clear the air plus make it so that I did not have to leave the beach house for a afternoon. I use these 4 portable air cleaners now to help keep the indoor air quality nice in our beach beach house when there is bad air quality outside. So it was not wasted money at all. The portable air cleaners came of use after I was done our painting of our home.
