When you are doing any kind of indoor painting, it is always important to have superb ventilation within the house.
The superb way to do this is to do all painting while I was in the time of the year when it is either frigid or just proper hot and cold temperatures.
You never want to do it in the warm Summer time weeks of the year. Because you will need to have windows opened and have fans blowing. You would not want to be running your central air conditioner 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 purification idea while you have the windows open. By having a portable air purification idea 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 home a few years back. They genuinely helped clear the air and make it so that I did not have to leave the home for a afternoon. I use these 4 portable media air cleaners now to help keep the air quality superb in my loft 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.
