Force of Nature: How the Weather Impacts Your Exterior Paint

Oklahoma sees some of the most extreme weather in the country. We are resilient and proud of our state's many quirks, from tornadoes to heavy rains and snow to sizzling heat. But we are also aware of the damages that seasonal changes can do to our homes' exterior paint.

What causes exterior paint weathering? Let's take a look.

1. Fading

Exterior paint can fade from the heat and direct sunlight. The sun's rays contain UV radiation, which can break down the paint's color, and in some cases, change the color completely.

2. Peeling

A common reason for exterior paint peeling is moisture. Moisture in the air can penetrate the paint due to leaks, missing or damaged gutters, or being close to the ground.

Paint can also begin peeling due to an amateur job. When the painting surface is not prepared correctly or is too low-quality, it can hurt the paint's durability.

3. Mildew

Caused by a fungus, mildew is a common problem in humid weather. (And we get a lot of that in Oklahoma!) Mildew can grow on any exterior surface, including paint. It's easy to spot mildew because it looks like a fuzzy green or black growth.

Probable causes of mildew include high humidity with a lack of direct sunlight. Paints that don't contain mildew-fighting ingredients can also be to blame. If you see mildew on bare wood, the wood is not sealed correctly.

4. Sagging

Saggy paint film is pretty easy to spot. The paint hangs down, and it's usually a sign that the paint was applied too thickly. However, environmental factors can also cause sagging. The paint will sag soon after application if temperatures are too cold or too humid.

5. Efflorescence

A problem that affects painted masonry efflorescence is the appearance of white or light-colored salt crystals on the paint's surface. It's usually caused by high humidity and a lack of a proper sealant. If the home has a basement, improper waterproofing can also lead to efflorescence.

6. Blistering

Paint blisters are tiny, round bubbles that appear trapped within the paint film. Heat can cause blisters to form due to solvent evaporation. When applied to wood, some paint blisters due to the wood absorbing moisture.

Humidity, dew, or rain can also cause blisters. This is particularly true if it's low-quality latex paint. If you see paint blisters, do not attempt to remove them yourself. You may cause more damage.

So, how do you resolve these common exterior paint weathering problems?

Well, the best option you have is to hire a professional to do the job. A professional will be able to apply the right amount of paint and sealant and will be able to use the right equipment to apply the paint properly. In addition, a professional will be able to identify the cause of the problem correctly and will be able to help you avoid it in the future.
