When you are doing any kind of indoor painting, it is always important to have great ventilation within the house.
The great way to do this is to do all painting during the time of the year when it is either cold or just typical temperatures.
You never want to do it in the sizzling summer time time weeks of the year. Because you will need to have windows opened as well as have fans blowing. You would not want to be running your central air conditioning while having windows open because this will make your energy bills high. Even if doing it only for a month while you paint the house. The best thing to do is to also have some kind of portable air purification plan while you have the windows open. By having a portable air purification plan 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 bought when I did a major paint task inside our apartment a few years back. They genuinely helped clear the air as well as make it so that I did not have to leave the apartment for a day. I use these 4 portable air cleaners now to help keep the air quality great in our home when there is disappointing 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.
