In normal sunny weather, it only takes two or three days for the paint to dry. When the latex paint is dry, you can open the window for ventilation (other furniture paints dry faster). Don't open the window in rainy days. Paint is not completely dry, ventilation will bring dust, affect the quality, crack and fall off. If it is environmentally friendly paint, and you can't feel the smell when you enter the house, open the window and open the door for ventilation for more than half a month.
