What Causes Premature Exterior Paint Failure?

Remember that smooth, clean, painted exterior you had not too long ago? Well, if you’re like many homeowners, you may be wondering where it went…

Unfortunately this is an all-too-common story, and it can leave you wondering: “Did I use the wrong paint? Was it a bad batch? Did I skip a step?”

Maybe, but maybe not.

In this article, we’re here to help solve the mystery and provide you with some explanation. Plus, knowing WHY paint failed can also help you avoid it in the future.

1. Poor Surface Preparation

One of the most significant contributors to premature paint failure is inadequate surface preparation. Remember, good prep is the key to paint adhesion and should include:

• Thorough Cleaning

• Sanding

• Priming

Skipping these steps is usually a sure recipe for peeling, cracking, and bubbling of the paint soon after application.

2. Low-Quality Paint

Sometimes it’s the paint itself that's the issue, and specifically the quality.

Low-quality paints may not be formulated to withstand the local climate and lack essential additives that contribute to durability. These paints often fade more quickly, are less resistant to weathering, and can begin to deteriorate shortly after application. Investing in high-quality paint with UV protection and moisture resistance can dramatically increase the lifespan of your paint job and make it a good, long-lasting investment.

3. Adverse Weather Conditions

Painting under, or immediately before, certain weather conditions can also severely affect the paint’s durability. Rain, high humidity, and extreme temperatures can interfere with the product’s ability to dry and cure correctly. For instance, painting in direct sunlight can cause the paint to dry too quickly, leading to cracks and wrinkles. Rain also will wash your work away if the paint hasn't had enough time to dry. So, the point is: it’s essential to plan your painting project around the weather, ensuring conditions are ideal for painting and drying.

4. Inadequate Application Techniques

“Painting is as simple as getting paint on the surface, right?” Well, it's a little bit more involved than that. Inadequate application techniques, such as improper brush strokes, using the wrong type of brushes or rollers, applying uneven layers, or even just rushing through the process can all lead to premature paint failure, too. Hiring professional painters or carefully following best practice application methods can help avoid these issues.

5. Moisture Damage

When moisture penetrates through the paint, it can lead to blistering, peeling, and the growth of mold and mildew. The solution? Ensuring that your home’s exterior is properly sealed and that any cracks or gaps are filled.

You can also use paints that are specifically designed to be moisture resistant to get that extra layer of protection.

6. UV Radiation

And lastly, ultraviolet (UV) radiation from the sun. Just like us, paint can only stand up to so much sun exposure. Over time the sun can degrade the chemicals in paint, leading to fading and that familiar chalk texture. But why would this lead to premature paint failure? Well, vibrant colors or rich tones tend to fade quicker in any case, but if you are in a particularly hot climate it will just expedite the process.

What's the Takeaway?

We understand that premature paint failure can be a frustrating and costly issue, but the good news is that it's often preventable! By understanding and addressing these common causes—ranging from poor preparation to environmental factors—you can ensure that your paint job remains vibrant and durable for years to come!
