Exterior painting does more than boost your home’s curb appeal; it safeguards the siding material underneath. However, because it is exposed to the elements, paint can fade over time, reducing the visual appeal of your property. Below is a guide for preventing this issue.

How Does the Sun Affect Exterior Paint?

The biggest issue when it comes to the sun and your exterior painting is ultraviolet radiation. UV rays affect the chemical bonds found in paint on a molecular level, leading to damage and a shorter lifespan.

Fading, also known as photodegradation, is a slow process where the sun’s intense rays change and weaken the paint color. Dark or bright colors are the most noticeably affected, turning vibrant tones into dull hues. 

You may also notice a white dusty film over the surface of the paint known as chalking. UV rays change the molecules of the paint so much that a new coat will not adhere correctly, requiring a painting contractor to prepare the surface properly to revitalize the color.

Visible damage, such as blistering and peeling, may also occur. Blistering is the result of an area losing its sticking quality, so the paint can no longer adhere to the surface. This bubbling can also lead to peeling, which then lets in moisture and debris, causing even more separation.

How to Prevent Harsh Effects

The sun will shine and UV rays will beat down, but there are steps to take that can lower the risk of damage. First, choose high-quality paint that includes UV inhibitors to reduce the sun’s impact. Ensure that the type of paint you select is the right one for the material on which it will be placed. The paint you would use on siding, for example, is not necessarily the right choice for masonry because of alkalinity levels and its effect on stone.

As for colors, certain hues do not show damage as much as others. Tans, browns, beiges, and similar subtle neutrals fade more slowly and less noticeably than bright blues or yellow.
