What Are Elastomeric Coatings and How Are They Used?


Elastomeric coating is an above-grade exterior wall or roof coating that is approximately 10 times thicker than paint. It forms an incredibly thick yet flexible coating that helps waterproof the exterior of a structure. Unlike other types of coatings or paints, it can bridge hairline cracks to complete an airtight waterproof seal. It is a suitable material for use on surfaces such as stucco, concrete, masonry and more. Elastomeric coatings can be used on walls as well as roofs. When the elastomeric coating is applied it is in liquid form, it completely dries, hardens and bonds to the structure and yet remains flexible, moving, bending and flexing as the structure underneath moves, bends and flexes. In addition to providing a waterproof protective coating to a structure, it also helps protect the structure from damage. Elastomeric coating is chemical and mildew. It can be tinted to a number of colors and retains its color very well long-term. For these reasons, it helps maintain the appealing look of the exterior of the building and wards off the less appealing look of damage, wear and tear.

As more and more people and businesses try to become more energy efficient in order to save money and be more eco-friendly, they are looking for every possible way to “go green.” One way to do so is with elastomeric coating. Elastomeric coating is heat resistant and helps drastically improve the energy efficiency of whatever building it is applied to. Because they are UV resistant, they essentially act like round the clock “sunblock” for your structure. It offers long term durability for a building which is important for many homeowners and business owners. While it is commonly used in industrial applications, it can be used in residential applications as well and Bob Vila points out that it is a great option for homes built in extreme weather climates, “These days just about every paint company offers their version of a weatherproof coating. Elastomeric coatings that retain their flexibility over a wide range of temperatures are becoming popular solutions for homes in storm or extreme-weather regions. The applicability to a host of surfaces adds to these products’ appeal.” It is also a cost-effective solution when compared to many alternatives. While elastomeric paint is applied in a similar fashion to paint, it is not a job for a novice or DIYer. Elastomeric paint requires expertise, knowledge and safety precautions and should only be applied by an experienced professional. Find an experienced painting contractor that is knowledgeable about elastomeric coatings and they will offer their guidance based on on-the-job experience and will help you achieve the look and results that you desire.
