Choosing Enamels or Acrylics for exterior use

We would generally recommend the use of acrylics in exterior situations. As enamels age they become very brittle and chalky and therefore have a tendency to crack and flake off the surface. Acrylics, however, retain their colour better, do not chalk to any great extent and do not become brittle, giving a longer lasting, more durable paint finish.

When embarking on an exterior painting project, the choice of paint plays a pivotal role in determining not only the aesthetics but also the longevity and durability of the finish. Many homeowners find themselves torn between using acrylics and enamels. Yet, after in-depth research and hands-on experience, we find ourselves leaning towards a strong recommendation: Acrylics.

The reason behind this is multifaceted. Enamels, although historically popular for their glossy finish and smooth application, have a significant downside. As they age, enamels undergo a process where they become notably brittle. This brittleness results in a surface prone to chalking. The term ‘chalking’ in painting refers to the formation of a powdery substance on the paint’s surface. Over time, this leads to the paint losing its original luster and vibrancy. Moreover, this brittleness and chalking combined pave the way for the paint to crack, subsequently leading to unsightly flaking. This means that after investing time, money, and effort, the outcome might not stand the test of time, requiring frequent touch-ups or even complete reapplications.

In contrast, acrylic paints offer a host of advantages for exterior situations. Foremost, they are renowned for their ability to retain colour brilliance over extended periods. This means your painted surface will stay looking fresh and vibrant for years to come. Furthermore, acrylics resist the chalking phenomenon to a significant degree. But perhaps the most vital advantage is their flexibility. Unlike enamels, acrylics do not turn brittle with age. This flexibility ensures that the painted surface can withstand environmental changes, minor expansions, and contractions without manifesting cracks or flakes. The result? A longer lasting, more resilient, and durable paint finish that offers homeowners true value for their investment.

For those considering the addition of solar panels or already having them installed, it’s worth noting the importance of the paint choice for the surrounding roof area. Solar panels often mean that a portion of the roof is shaded, leading to differential weathering. Acrylics, with their superior resistance to chalking and brittleness, are the preferred choice for such situations. Their enduring finish ensures that the roof around the solar panels remains consistent in appearance and durability, enhancing the overall aesthetic appeal and lifespan of the rooftop.

In conclusion, while both enamels and acrylics have their merits, when it comes to exterior applications, the balance tilts overwhelmingly in favor of acrylics. For longevity, vibrancy, and durability, they are the undisputed champions.
