House exterior paint failures are common problems. While it’s comforting knowing you are not alone, it doesn’t change the fact that you have a serious problem that must be addressed. The exterior paint of your home is important. And not only for the house’s curb appeal. It also serves as a protective barrier against the elements. However, over time, various factors can lead to paint problems that compromise both the aesthetic appeal and structural integrity of your house. So, let us explore the most common house exterior paint problems and their causes, and discuss effective solutions to address them.
Common problems with house exterior paint
Peeling Paint
Peeling paint is a common issue that occurs when the paint film separates from the underlying surface, resulting in unsightly flakes and patches.
Why does it happen? It may happen if the exterior house painting was not done correctly, to start with. If there was poor preparation, the paint products were not suitable, or the house painters applied the coatings over the old paints, the job won’t last. The paint will peel. Exterior paint also peels due to moisture infiltration.
How to fix peeling paint? The loose paint must be removed with a scraper or wire brush. Then, the damaged areas should be repaired before the surface is primed. Lastly, the surface should be covered with a new coat of high-quality exterior paint.
Blistering
Blistering occurs when bubbles or blisters form beneath the paint film, typically due to moisture vapor trapped beneath the surface. This problem can also result from applying paint to a damp surface or using low-quality paint. No wonder you need to trust such jobs to skilled exterior home painters. To remedy blistering, carefully scrape away the affected areas, sand the surface smooth, prime as needed, and repaint with a moisture-resistant exterior paint.
Fading
Fading is a natural occurrence caused by prolonged exposure to sunlight and UV rays. Such an exposure results in a loss of color intensity and vibrancy. While fading is inevitable over time, choosing high-quality, UV-resistant paint can prevent premature fading. Once again, it’s a matter of finding experienced painting companies that would recommend and use suitable products. To refresh faded paint, thoroughly clean the surface. Then, apply a fresh coat of paint in the desired color. To avoid premature fading in the future, not only should you choose a quality paint product but would be recommended to apply a protective clear coat for added durability.
Cracking
Cracking – aka flaking, refers to the formation of cracks on the paint surface. This is often caused by age, temperature fluctuations, or substrate movement. It may also happen if the paint is low quality, to start with. To address cracking, start by cleaning the surface and filling any cracks with a flexible exterior caulk or patching compound. Once the repairs are complete, apply a new coat of paint to seal and protect the surface.
Mildew and Mold
Mildew and mold growth on exterior painted surfaces creates green or brown stains. These fungal growths thrive in damp, shaded areas and are often exacerbated by poor ventilation and high humidity levels. To combat mildew and mold, thoroughly clean the affected areas with a mixture of bleach and water. It’s vital to let these areas dry completely. Then, you should apply a mold-resistant primer before repainting.
Efflorescence
Efflorescence is the formation of white salty stains. They are salty white deposits coming from the paint on surfaces like masonry and brick. This happens due to high levels of moisture that manage to draw out salts from the concrete or brick, compromising the surface’s appeal. To effectively address the problem, it’s best to first identify the source of moisture – often noticed in nearby downspouts, gutters, and other sources of water. Once this is done, brush off the white deposits, clean the area, wait to dry, and repaint. If we are talking about a brick surface, it’s hard to paint. You’d better hire a brick wall painting team.
As a conclusion
It’s fair to say that regular inspections and timely repairs can keep the exterior house walls in good shape for a long time. Since no exterior paint problem is good for the house’s aesthetics and even integrity, be sure of the quality of paints and the quality of the painting job, to begin with. And if something goes wrong, address the problem promptly using high-quality materials to protect your home from the elements and ensure a lasting and attractive finish that enhances your home’s curb appeal for years to come.
