Elastomeric Paint – What is it, and why should you choose it?

There are many different types of paint used in commercial and industrial painting. One of the most popular is elastomerics. This water-based paint is formulated from an acrylic resin, which gives it incredible durability and longevity.

Commercial painting contractors often use this thick paint for building exteriors because of its excellent properties. Elastomeric coatings are very flexible, with high color retention and superior waterproofing capabilities.

The qualities of elastomerics

Elastomeric paint is waterproof and weatherproof, able to withstand the harsh environmental conditions that building exteriors face. This tough coating creates a barrier that protects substrate from moisture damage. In addition, the paint itself resists fading in sunlight, heat, and wind.

The elongation capabilities of elastomerics are impressive as well. This type of paint is completely elastic and flexible, which allows it to expand and contract along with the material beneath under extreme heat or cold. This elasticity also allows elastomerics to bridge small surface cracks and prevent them from worsening.

What does elastomeric paint look like?

Despite the fact that elastomerics are thicker and more durable than ordinary exterior paint, you can’t tell by its appearance. Elastomeric coating can appear just the same as regular paint, and is available with just as many options.

There are both smooth and textured varieties of elastomeric paint. Similar to standard paint types, the smooth variety can be “flat” (with no gloss), or have a satin sheen. Textured elastomerics can be applied with different patterns, and is often used to disguise imperfections in a substrate’s surface.

Regarding color, elastomeric coatings can be tinted to nearly any hue. In most cases, earth tones or pastels are used, because this type of paint is most suitable for exterior surfaces.

How elastomerics can help your facility

Elastomeric paint is used primarily for commercial and industrial building exteriors, though there are other potential applications. Some of the best uses for elastomerics include:

  • Exterior waterproofing and weatherproofing, including roof coatings
  • Repairing seasonal wear and tear to a building’s exterior
  • Improving the aesthetic appeal of a facility
  • Coating industrial machinery, steel structural components, and exterior features like walkways and handrails


The best surfaces for applying elastomeric coatings include brick, stucco, concrete, and fiber cement. However, many types of surfaces can benefit from the application of elastomeric paint.

The application process

Precision and timing are important when applying elastomeric coatings. When this paint is not applied with the proper thickness, the coating will wear out much faster and require more frequent repainting.

To ensure that your facility will stay looking great for years to come, it’s important to work with an industrial painting contractor who has experience using elastomerics in commercial or industrial settings.
