There are a few factors to consider when making this decision, including the condition of the surface you’ll be painting, the type of paint you’re using, and the type of primer you would use. If the surface you’re painting is in good condition and has been previously painted, you may not need to prime before applying elastomeric paint. However, if the surface is in poor condition or needs to be repaired, priming may be necessary to ensure the proper adhesion of your paint.

What is Elastomeric Paint?

Elastomeric paint is a type of polymer paint that contains high levels of elasticity. It has the ability to stretch and recover without breaking or cracking, making it a popular choice for painting surfaces that are prone to movement or expansion. Elastomeric paint is commonly used on exterior walls, roofs, and concrete surfaces, but it can also be used on interior walls.

Elastomeric paint is made up of a variety of ingredients including acrylic, water, and fillers such as clay or titanium dioxide. It also contains special additives that provide the elasticity and durability that sets it apart from other types of paint. Its thickness and flexibility allow it to fill cracks, gaps, and other imperfections in the surface it is applied to, creating a smooth, even finish.

Elastomeric paint comes in a variety of colors and can be customized to suit specific needs. It is resistant to weather, UV rays, and water damage, making it an excellent choice for areas that are exposed to harsh elements. Additionally, its ability to stretch and recover can reduce cracking and prevent water infiltration, which can lead to mold and mildew growth.

How does Elastomeric Paint work?

Elastomeric paint is specially formulated with a unique combination of polymers and resins that allow it to expand and contract with the surface it is applied to. This paint has exceptional flexibility, allowing it to stretch as much as six times its original size. This elasticity is crucial because it enables the paint to bridge hairline cracks and gaps—something that regular paint cannot do which can lead to the paint chipping or flaking off over time.

Elastomeric paint creates a seamless and waterproof membrane-like coating over the surface it is applied to. This membrane prevents moisture and water from penetrating into the surface, but at the same time, allows any existing moisture or water vapor to escape through the film. This feature is important in preventing any future damages due to waterlogging or moisture accumulation in the surface being painted.

Advantages of using Elastomeric Paint

  • Exceptional Elasticity
  • Waterproof and Flexible Membrane-like Coating
  • Prevent future damage due to waterlogging or moisture accumulation

Application of Elastomeric Paint

Before applying Elastomeric paint, make sure that the surface you are going to paint is clean, dry, and free from grease, dirt, and other contaminants. It is essential to do this because elastomeric paint will not adhere well to a dirty or contaminated surface.

Once you have prepared the surface, you can now apply the Elastomeric paint using a brush or a roller. Be sure to spread the paint evenly over the surface and work it into all the nooks and crannies of the surface you are painting.

After applying the first coat of Elastomeric paint, let it dry completely before applying a second coat if necessary.

Elastomeric Paint Coverage

Elastomeric paint covers a surface more thickly than regular paint, so you will need less coverage of it to achieve a good result. This coverage depends on the surface’s roughness and porosity and generally ranges from 50 to 150 square feet per gallon.

Rough SurfaceSmooth Surface
50-100 square feet per gallon100-150 square feet per gallon

Elastomeric paint is a great solution for surfaces that are exposed to harsh weather conditions, erosion, and other factors that can cause damage over time. The elasticity of this paint provides flexibility and waterproofing to the surfaces that it is applied to, making it a popular choice among homeowners and contractors alike. Before applying Elastomeric paint, make sure to prime the surface to get the optimal protection and performance, and ensure that the surface is clean and free from contaminants.

Can you Paint without Priming with Elastomeric Paint?

One of the biggest advantages of using elastomeric paint is its ability to resist cracking, chipping, and peeling. However, some people may wonder if they need to prime their surfaces before applying elastomeric paint. Here are some important factors to consider:

  • The condition of the surface: If the surface is in good condition with no peeling or loose paint, priming may not be necessary. However, if there are areas where the paint has peeled or there is evidence of water damage, priming is recommended to ensure proper adhesion.
  • The type of surface: Elastomeric paint can be applied to a variety of surfaces, including stucco, concrete, and brick. However, different surfaces may require different types of primer to ensure proper adhesion. Be sure to follow the manufacturer’s recommendations when selecting a primer.
  • The quality of the elastomeric paint: While some lower-quality elastomeric paints may claim to not require priming, it is still recommended to ensure proper adhesion and longevity of the paint job. Higher-quality elastomeric paints will typically include instructions for priming.

Ultimately, while it may be possible to apply elastomeric paint without priming in certain situations, it is generally recommended to prime beforehand to ensure the best possible results. Taking the extra time to properly prepare the surface and prime as needed will result in a longer-lasting, more durable paint job.

Importance of Priming before using Elastomeric Paint.

If you want to ensure that your elastomeric paint will adhere well and provide long-lasting protection, it is essential to prime the surface first. Primer is the foundation for any paint job, particularly for elastomeric paint which is known for its flexibility and ability to stretch without cracking.

  • 1. Enhances Adhesion – The primary reason for priming before painting is to improve adhesion. When the surface is properly primed and prepared, the paint can bond better, ensuring maximum adhesion.
  • 2. Seals the Surface – Primers can come in different formulas, and one of the most important functions is to seal the surface to be painted. This is especially crucial when working on porous or irregular surfaces. By using primer, you seal the surface to prevent the paint from seeping in and causing adhesion problems.
  • 3. Fills – Primers can help fill in small cracks, pits, and holes in the surface, ensuring that these imperfections don’t show through the final paint job.

Moreover, elastomeric paint tends to have a higher viscosity than regular paint since it contains more solids. That is why applying it directly on a surface without priming may lead to unevenness and poor coverage. With proper priming, the surface becomes smoother, which makes it easier and quicker for the elastomeric paint to be applied.

Finally, when painting a surface that has been previously painted, priming will ensure that the surface has been sufficiently prepared. This is important because the previous paint may contain contaminants or be of unknown origin. Priming helps to ensure that the new paint will adhere well to the surface.
