When Should You Use Elastomeric Paint?

When painting a home, there are many options regarding materials and finishes. In recent years, elastomeric paint has become increasingly popular among homeowners, contractors, and painters as a durable and reliable coating. But when should you use it?

It is recommended for painting surfaces exposed to extreme weather, wear and tear, or water damage. It provides an effective waterproof seal and is particularly suitable for surfaces prone to cracking, chalking, and fading.

In this article, I’ll be discussing what elastomeric paint is, the benefits of using it, when it should be used, and more. I invite you to explore the following sections to learn more about elastomeric paint and when it should be used.

Elastomeric Paint: The Basics of Application and Use

So let’s talk about elastomeric paint, a specialized type of paint designed for masonry and concrete surfaces. It’s made up of a combination of acrylic resins and elastomers, giving it unique properties. It’s a thick, stretchy paint that can fill in small cracks and crevices, creating a smooth and uniform surface.

How does it differ from Standard Paint?

Elastomeric paint is much thicker. Like, we’re talking up to ten times thicker. This added thickness allows it to stretch and move with the surface it’s applied to, making it much more durable and long-lasting. It’s also more resistant to environmental factors like wind-driven rain, so it’s great for protecting your home from the elements.

What Surfaces Is Elastomeric Paint Good For?

It’s perfect for masonry and concrete surfaces, like stucco, poured concrete, roofs, bricks, and metal surfaces.

It’s also great for hiding hairline cracks and creating a uniform, pinhole-free finish. It’s even been used in commercial and industrial settings, like bridges, parking garages, and airports. The point is that elastomeric paint is a versatile option that can protect many surfaces.

The Benefits of Using Elastomeric Paint

Now, you may ask yourself why I should use elastomeric paint. It is a powerful paint used to protect and beautify a surface. Here are some of the benefits of using elastomeric paint:

Seals Hairline Cracks

One of the biggest benefits of using elastomeric paint is its ability to seal hairline cracks. The thick, stretchy nature of the paint allows it to fill in small gaps and crevices, creating a smooth and uniform surface. This can be especially useful for older homes with masonry or concrete surfaces with cracks or imperfections.

Prevents Mold and Mildew

It creates a barrier that prevents water from penetrating the walls, which can help prevent mold and mildew growth. This is especially important in areas with high humidity or heavy rainfall.

Withstands Environmental Factors

Elastomeric paint is also highly resistant to environmental factors such as wind-driven rain, making it an excellent choice for protecting your home from the elements.

It’s been known to hold up for up to 10 years or more, depending on the paint’s surface and quality. This means you won’t have to worry about repainting your home as often, saving you time and money in the long run.

When to Use Elastomeric Paint?

It’s time to come to the main point of this guide. When should you consider using elastomeric paint? So I’m going to break this down for you.

Ideal Conditions

One of the most important things to consider when using elastomeric paint is the conditions under which you’ll apply it. Ideally, the temperature should be above 40 degrees Fahrenheit, and the surface should be dry.

If it’s raining or humid, it’s best to wait until the weather clears up before applying the paint. If you can’t avoid working in wet conditions, protect the area with an awning or tarp to keep the surface dry.

Preparing the Surface

Proper surface preparation is critical when using elastomeric paint. This means cleaning the surface thoroughly and removing any dirt, grease, or other debris. Any cracks or holes should also be filled and sanded smoothly before applying the paint. The surface should also be dry and free of loose or flaking paint.

Applying the Paint

Once the surface is prepared correctly, it’s time to apply the paint. Elastomeric paint is thicker than standard paint, typically applied in two or more coats.

It’s also essential to use the right tools, such as a high-quality paint roller or brush, to apply the paint evenly and smoothly. Be mindful of the weather conditions; if it’s too hot, the paint can dry too quickly, leading to cracking. If it’s too cold, it will not dry properly.

Can Elastomeric Paint Be Used to Speed Up the Drying Process of Epoxy Paint?

Yes, elastomeric paint can speed up the epoxy paint drying time. The high elasticity and flexibility of elastomeric paint allows it to bond well with epoxy paint and accelerate the overall drying process. This can be particularly useful for quick turnaround projects or in environments where fast drying times are essential.

Do you need to prime before using elastomeric paint?

Yes! Priming is essential before applying elastomeric paint because elastomeric coatings do not penetrate far below the surface of what you are painting. They create a smooth and uniform surface, providing a better base for the paint to adhere to.

They also fill in small gaps, cracks, and pores that could cause the paint to peel over time. Applying a good and compatible primer will ensure that the elastomeric paint adheres to the surface properly and lasts for a long time.

It is always recommended to consult the manufacturer’s instructions for specific instructions on primer requirements.

What should you consider before applying elastomeric coatings? 


Elastomeric paint is a specialized type of paint that is designed to protect masonry and concrete surfaces. It’s thicker and more flexible than traditional paint, making it an excellent option for protecting your home from the elements.

It’s also versatile and can be used on a range of surfaces. The benefits of using elastomeric paint include sealing hairline cracks, preventing mold and mildew, and withstanding environmental factors.

Its cost is generally higher than traditional paint, but it’s worth considering for its durability and long-term savings. Remember to wait for the right conditions, prepare the surface properly and consider hiring a professional painter to ensure proper application.
