One of the biggest factors that affects the quality and lifespan of exterior paint is the weather. So how does weather affect a structure’s exterior paint?
Temperature: always make sure to read the instructions when it comes to architectural paint because paint and stains are always affected by temperature and they can only withstand much. Always remember that the life span of the paint is partially dependent on what kind of temperature it is exposed to on a daily basis.
Sun: This is one of the biggest factor which affects a paint’s quality and finish. As much as possible, refrain from working where the sun is shining down directly on the wall or structure you are painting and this can result in the paint not drying properly . Take note that if the temperature is too hot then the curing process may result into wrinkles and or bubbles forming. Furthermore, extreme heat from the sun can virtually expand and then a sudden shift into a colder temperature can cause calking applied on those spaces to eventually crack down.
Wind: Optimal bond formation requires ample time and wind can speed up the process to much that the paint may not end up as to what it should be. Wind also tends to carry dirt and dusts on the paint which can potentially distort the finish. It can also potentially cause mildew and mold to grow on it thanks to the wind.
Moisture: Another effect of weather is that it can cause moisture and dampness on the paint which can be a problem because it can keep the paint from drying on time and cause mildew to grow on it. If the humidity is above 90% and or there are thick fog surfacing then might as well reschedule.
