How long have you used gush paint? Did any mold appear after using gush paint?
What is the meaning of cross ventilation? Bedroom door always closed and only open windows can it be cross ventilation?
I have engaged the painter to come in end Nov... so won’t know until it’s all done.
Cross ventilation meaning having a passage for air to pass through. So having only the windows open does not count. Having an air circulator like vornado also helps move the air around the house.
