What is Permeability?

In exterior painting and coatings, permeability is a term that often gets overlooked but holds significant importance. Permeability refers to a material’s capacity to allow fluids or gases to pass through it. In the context of exterior paint, permeability determines how well the paint can let moisture vapor escape from the surface to which it is applied.

At first glance, this might not seem like a substantial factor, but when you dive deeper into the science behind painting exteriors, it becomes clear that permeability ratings are critical. In this article, we’ll look at what permeability means regarding exterior paint, why it’s important, and how choosing a high-permeability product like Rhino Shield Ceramic Coatings can make all the difference for your home or building’s exterior. 

How Permeability Applies To Exterior Paint

Permeability ratings for your exterior paint matter because it directly impacts the durability of the paint and the integrity of the structure it covers.

An impermeable coating can cause a host of problems. When moisture vapors can’t escape, it often leads to blistering and peeling of the paint. This trapped moisture can also promote the growth of mold and mildew, or even worse, it can cause the substrate to fail altogether. Using paint with low permeability may seem like a good idea initially for moisture protection, but the issues pile up over time, proving otherwise. We encourage you to consider Rhino Shield ceramic coatings with their best-in-class permeability rating.

The Permeability Benefits of Rhino Shield

Rhino Shield is a unique product that isn’t just an exterior paint – it’s a ceramic coating with a best-in-class permeability rating. Rhino Shield is designed to allow moisture vapors to escape, preventing the typical issues associated with impermeable coatings we mentioned above.

In relation to permeability, Rhino Shield offers numerous benefits:

  • Longer Lifespan: Rhino Shield doesn’t trap moisture thanks to its high permeability, which means the coating remains intact for longer. You don’t have to worry about frequent repaints, and with a 25-year transferable warranty, you know Rhino Shield is built to last.

  • Better Protection from the Elements: Rhino Shield forms a protective barrier that stands up to various weather conditions, but unlike traditional paints, it doesn’t seal in moisture. This unique characteristic makes Rhino Shield the ideal coating for protecting your home against the elements.

  • Less Maintenance: The superior permeability of Rhino Shield means fewer problems like peeling, blistering, or substrate damage. Less damage equals less maintenance, saving you time and money.

FAQ About Rhino Shield and Permeability

Is Rhino Shield breathable?

Yes, Rhino Shield is breathable. One of the unique features of Rhino Shield is its high permeability, which allows moisture vapor to escape from the exterior surface, preventing the build-up of condensation and associated problems like mold and mildew.

Is Rhino Shield waterproof?

Rhino Shield is water-resistant, which means it provides excellent protection against water damage. While it allows moisture vapor to escape, it also effectively repels liquid water from rain, dew, and snow, ensuring your building’s exterior remains dry and protected.

Does Rhino Shield stop mold growth?

The permeability of Rhino Shield can significantly reduce mold and mildew growth. By allowing moisture vapor to escape, it helps prevent the damp conditions that mold and mildew thrive on. However, it’s important to note that no paint or coating can entirely ‘stop’ mold growth if other conditions for mold are present.

How long does Rhino Shield last?

Rhino Shield is designed to last much longer than traditional paint. Its ceramic technology and high permeability contribute to its durability, often lasting up to 25 years. However, lifespan can vary depending on factors such as local weather conditions and the condition of the substrate.

Does Rhino Shield increase home value?

While it’s difficult to quantify exactly how much Rhino Shield increases a home’s value, its long-lasting, low-maintenance attributes are certainly appealing to potential buyers. In addition, Rhino Shield can enhance your home’s curb appeal, which can positively impact its overall value.
