When you are doing any kind of indoor painting, it is regularly crucial to have good ventilation within the house.
The good way to do this is to do all painting while in the time of the year when it is either frosty or just standard temperatures.
You never want to do it in the tepid summer time time months of the year. Because you will need to have windows opened plus have fans blowing. You would not want to be running your central while having windows open because this will make your energy costs 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 media air cleaner while you have the windows open. By having a portable media 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 media air cleaners I had bought when I did a major paint task inside my apartment a few years back. They genuinely helped clear the air plus make it so that I did not have to leave the apartment for a day. I use these 4 portable media air cleaners now to help keep the indoor air quality good in my home when there is bad air quality outside. So it was not wasted money at all. The portable media air cleaners came of use after I was done my painting of my home.
