The best amount of time to paint after pressure washing a house in Arizona is 4 hours to a day. During the hotter, dryer times it takes 2 to 4 hours to dry. The colder months can take up to a full day.
In more humid climates, it takes much longer for the paint to dry. You almost never reach 0% moisture content. This is because the moisture is being pulled into the wood or masonry.
In Arizona’s drier climate the moisture is being pulled away from the surface. This helps it dry faster. It’s always best to paint in the best weather for painting.
