Your Ultimate Guide to Applying Elastomeric Paint

Elastomeric paint is a highly durable and waterproof coating. A great option for outdoor surfaces that are exposed to the elements. Unlike traditional oil or latex paints, elastomeric paint has the ability to return to its original shape and size after being stretched or compressed. If you want a long-lasting and finished look for your outdoor project, elastomeric paint is the perfect choice. In this article, we’ll provide you with tips on how to apply elastomeric paint effectively and achieve a professional-looking result.

The application process for elastomeric paint may seem straightforward, but it can be tricky. It is always advisable to seek the help of a professional. Despite not requiring specialized brushes or rollers, proper application of elastomeric paint requires experience. You need a working knowledge of the basics of painting. This includes proper preparation of the surface. You need an understanding of the right consistency and thickness of the paint. You should also be mindful of the conditions during application. A professional will have the expertise to ensure the surface is properly prepped. The ability to apply the paint evenly, resulting in a smooth and long-lasting finish. With these tips on how to apply elastomeric paint, you can achieve a professional look for your outdoor project.

First, what is Elastomeric paint?

Elastomeric paint is a type of paint that has high elasticity and can stretch and move with the surface without cracking or peeling. It is made from a combination of elastic polymers, pigments, and solvents. The elastic polymers, typically acrylic or silicone, give the paint its elasticity. It has the ability to stretch and move with the surface.

Use it for outdoor surfaces that are exposed to the elements. Elements such as wind, foot traffic, or snow. Areas that are prone to movement or expansion and contraction due to changes in temperature and moisture. Elastomeric paint is also known for its durability and waterproofing qualities, making it an excellent choice for a long-lasting finish. Use it on surfaces such as stucco, concrete, masonry, and metal. It can be applied with a brush, roller, or sprayer.

Pigments provide the color, and solvents act as a medium for the paint and help to ensure even application. The exact composition of elastomeric paint can vary depending on the manufacturer and the specific type of elastomeric paint. Some elastomeric paints may also contain additional ingredients, such as UV inhibitors or mold inhibitors, to enhance their durability and resistance to environmental factors.


Proper surface preparation is essential for the successful application of elastomeric paint. A clean, smooth, and well-prepared surface will help ensure a strong bond between the paint and the surface. This results in a long-lasting and attractive finish. Before applying elastomeric paint, it is important to remove any dirt, grime, or old paint from the surface. For instance, use a quality detergent that won’t leave a residue or cause the surface to peel. If necessary, use a scraper or pressure washer to remove any oxidized or peeling paint. Failure to properly prepare the surface can result in a poorly adhered paint job. It may not last long and will not look as attractive as a properly prepared surface. Proper surface preparation is an essential step in ensuring a successful elastomeric paint job.

Filling cracks in stucco or masonry before applying elastomeric paint is an important step in ensuring a smooth and attractive finish. Small hairline cracks can easily be covered with elastomeric coatings without much hassle. However, larger cracks, greater than 1/16″, should be filled with a compatible substance. Use mortar or patching cement to prevent the paint from settling into the crack and creating an unsightly appearance. Use a fiber-reinforced tape for cracks that are not expected to spread. This can bridge the gap and provide additional stability. It is important to take the time to properly address any cracks in the surface before applying elastomeric paint.


Before applying elastomeric paint, it is important to follow the manufacturer’s recommendations for primer use and surface preparation. Firstly, Different surfaces, such as unpainted block or stucco, require different preparations compared to bare wood or previously painted surfaces. Choosing the right elastomeric coating for the surface is crucial to achieve a professional-looking result. Elastomeric coatings come in different formulations designed for specific surfaces. It is important to select the right product for the job. Keep in mind that elastomeric coatings do not penetrate deeply into the surface. An application of a primer is often important to ensure the paint adheres properly and lasts for an extended period of time. Following the manufacturer’s recommendations is a must. Moreover, taking the time to properly prepare the surface and apply the primer will help ensure a successful and long-lasting elastomeric paint job.


Proper application of a product is crucial to its success. Following the manufacturer’s instructions is the key to achieving a high-quality outcome. One important aspect to consider is the wet film and dry film thickness. Use these as indicators of the quality of the application.

Both WFT and DFT are important factors to consider when applying paint. They affect the final appearance and performance of the paint. If the WFT is too high, it can result in runs or drips. A too-low WFT can lead to an uneven or thin coating. Follow the recommended DFT to ensure proper coverage and durability.


Wet film thickness (WFT) refers to the thickness of a paint in its wet state, immediately after application. It is measured in mils (thousands of an inch) or micrometers.


Dry film thickness (DFT) refers to the thickness of a paint after it has dried completely. It is also measured in mils or micrometers and is the final thickness of the paint layer that remains on the surface after drying.

Staying within the recommended values for each item is important. It directly affects the performance and lifespan of the product. Opting for multiple thin coats instead of a single thick coat is usually the better choice. This ensures an even coverage without the risk of sagging or appearing lumpy. In conclusion, following the manufacturer’s instructions and paying close attention to the film thickness is vital for a successful application.

When painting, it is important to properly cover all surfaces, including difficult-to-reach areas around pipes, windows, and electrical boxes. Use a brush to apply paint to these areas precisely. For larger, flat surfaces, use a thick nap roller in an overlapping “V” pattern to cover the area efficiently. While airless sprayers can be used, they require significant equipment, special-sized spray tips, and professional training. This may not be available to the average do-it-yourself homeowner. For this reason, a brush and roller may be a more practical option for DIY projects.
