The professionals are Unicoat Industrial Roofing are experts in all types of roof coating solutions – but commercial property managers may not understand their various options. One of these choices is elastomeric coatings, a specialized class of protective coatings designed to provide exceptional flexibility, durability, and water resistance.

Elastomeric roof coatings are commonly used on flat or low-slope roofs, especially in commercial and industrial buildings. These coatings are highly effective in protecting roofs from water damage, UV degradation, and thermal expansion. They can also be applied to metal, asphalt, and concrete roofing systems to extend their lifespan and improve performance.

By utilizing elastomers, or rubber-like materials, elastomeric coatings are able to stretch and return to their original shape without cracking or peeling, making them ideal for surfaces that experience frequent movement, expansion, or contraction due to temperature fluctuations or mechanical stress.

Composition and Properties of Elastomeric Coatings

Elastomeric coatings are made from polymer-based materials, often acrylic, silicone, polyurethane, or elastomeric bitumen, which impart significant stretchability and resilience. The primary characteristic that distinguishes elastomeric coatings from standard paints is their high elongation capacity—these coatings can stretch between 100% and 400% beyond their original size without breaking. This makes them highly effective in accommodating the movement of building substrates, especially in regions where temperature shifts can cause materials to expand and contract.

Additionally, elastomeric coatings form a seamless, monolithic film once applied. This film is typically resistant to water penetration, UV degradation, and environmental pollutants, providing long-lasting protection for the substrate underneath. In some formulations, elastomeric coatings may also offer superior resistance to corrosion, mold, and mildew, depending on the specific needs of the application.

Key Benefits of Elastomeric Coatings

Flexibility and Durability: The primary benefit of elastomeric coatings lies in their ability to stretch and adapt to changes in the substrate without compromising their structural integrity. This flexibility makes them an excellent choice for surfaces that experience continuous movement, like concrete or metal roofs. The durability of elastomeric coatings also ensures long-lasting protection, reducing the frequency of maintenance or reapplication.

Waterproofing: Elastomeric coatings are highly effective in preventing water infiltration. The seamless nature of the film, combined with its elastic properties, ensures that the coating can bridge small cracks and gaps in the underlying surface, preventing leaks. This makes elastomeric coatings especially popular in roofing applications, where they can help protect against water damage.

UV Resistance: Many elastomeric coatings are formulated with UV inhibitors that provide resistance to ultraviolet radiation. This prevents the coating from breaking down or degrading under prolonged sun exposure, making it an ideal choice for exterior applications such as roof coatings and exterior wall finishes. UV resistance helps extend the life of the coating and maintain its protective properties.

Energy Efficiency: Some elastomeric coatings are reflective, meaning they can deflect solar heat away from buildings, thereby reducing cooling costs. These cool roof coatings are particularly beneficial in hot climates, as they can significantly lower the internal temperature of a building, leading to energy savings and improved comfort.

Aesthetic Appeal: Elastomeric coatings are available in a wide range of colors and finishes, allowing for both functional and decorative applications. These coatings can be tinted to match the surrounding environment or building design, providing an aesthetically pleasing finish while maintaining the protective properties of the material.
