Extreme winter or hot summers, humid days or dry days, high humidity or low humidity – every weather impacts a paint job. Painting the interior of a building does not have to wait for specific weather. You can paint interiors in any weather because you can adjust the temperature and humidity of your home accordingly.
But when it comes to exterior paint, things are entirely different. You have to face many issues that you cannot control. In such circumstances, rather than controlling the temperature and humidity around your project, you have to adjust your project according to the weather.
You need to consider all these weather factors to get the best results from your exterior paint project. These factors are broken down in this article.
Weather Conditions and their impact on Exterior Paint
- Ambient Temperature
At low ambient temperatures, the paint thickens and does not dry as well if the temperature is too cold. So you can see long cracks in the paint, and your paint can sag. And also, it’s almost impossible to apply paint in extreme cold weather. Most manufacturers recommend painting at 50 to 90 degrees Fahrenheit, while some companies have manufactured products that are effective at 35 degrees.
In hot weather, the paint dries very quickly, due to which the binding and adhesion properties of the paint do not work correctly, and wrinkles and bumps appear. But heat and direct sunlight have different effects on water-based and oil-based paints, so reading the manufacturer’s instructions before applying the paint is inevitable.
- Relative Humidity
Relative humidity plays a significant role in the success of paint applications. Humidity has a great deal of impact on the paint’s adhering properties. For example, when humidity is high, there is moisture on the surface because it is exposed to water vapors. So when the paint is applied, you will get bubbles and peeling.
The recommended humidity range is between 40 and 70 percent because the paint’s adhesion will work properly within this range.
- The Wind
You may see cracked blasting paint and take it as the result of heat and humidity when it is not. Apart from temperature and humidity, the wind is also a factor that affects paint’s adhesion properties. If the paint is applied during a windy day, it does not get a proper period to dry, and the wind dries it prematurely. Therefore, apart from temperature and humidity, it is crucial to consider wind speed too.
