What is Elastomeric Paint? Benefits Uses & Application Tips

The paint used on the exterior of a home or building is different than the paint used for interior painting. It is important to consider what type of paint you should use on the exterior of your Phoenix or Tucson home because Arizona has a harsher climate with extreme temperature and intense UV radiation. This can cause paint to fade or crack, ultimately deteriorating much quicker than in states with mild climate.

So, when you are ready to paint your home, one option you may want to consider is using an elastomeric paint for your exterior painting project. In this article, we’ll explore what elastomeric paint is, how it works, its key benefits, and how to properly apply it for long-lasting results.

What Is Elastomeric Paint?

Elastomeric paint is a high-build exterior paint coating that is extremely durable and water resistant. It is designed to protect surfaces such as exterior walls or roofs through its ability to expand and contract, which makes it an idea product for exterior surfaces such as stucco, brick and masonry, and concrete.

Unlike typical or standard exterior paints, elastomeric coatings are thicker and more elastic. Elastomeric coating can stretch anywhere from 300% to 800% depending on the formulation. This high level of elasticity allows the coating to bridge gaps and cracks and accommodate structural movements and temperature-induced expansion.

Key Benefits of Elastomeric Paint

There are several benefits to elastomeric paint coatings:

• Superior Waterproofing: Elastomeric paint is excellent at waterproofing and preventing water from seeping into surfaces like stucco or brick, helping to reduce the risk of mold, mildew and damage by moisture.
• Crack Bridging and Flexibility: Elastomeric coatings can expand and contract to ensure that cracks and other imperfections are covered, preventing any further deterioration of the surface.
• Durability: Elastomeric paint lasts longer than most standard exterior paint types. Because it is thick and elastic to be able to withstand more severe weather conditions, it is durable and won’t be affected by sunlight, rain, strong winds and other climate impact.
• Energy-Efficient: Elastomeric paint coatings have reflective properties that contribute to deflecting heat from buildings, helping to reduce excessive AC use during the summer.
• Ideal for Harsh Climates: Arizona has harsher temperatures, so elastomeric paint is a good investment to be able to withstand the heat and help to prevent cracks and peels, ensuring a long-lasting exterior finish.

When Should You Use Elastomeric Paint on Stucco?

Due to Arizona’s hot and dry climate, stucco home builds are extremely common. Stucco is made from mixing cement, sand, lime, and water. It is an incredibly durable finish that is highly beneficial for the scorching summer heat. But how do you properly apply it to get optimal results? Let’s review the best application tips and techniques.

Tips on Applying Elastomeric Paint

Elastomeric paint is ideal for a variety of exterior surfaces, including:

• Stucco – Helps prevent cracking and moisture penetration.
• Concrete – Seals pores and enhances durability.
• Brick and Masonry – Provides added protection against weathering.
• Wood and Metal (with Proper Priming) – Can be applied with the right surface preparation.

Preparation Steps

In order to get the best results from elastomeric paint coatings, preparation is key and following the steps in the right order will provide the best outcome.

1. Clean the Surface – Remove dirt, mold, and any loose paint to ensure proper adhesion.
2. Repair Cracks and Holes – Fill in any significant cracks with an appropriate filler or sealant.
3. Apply a Primer (If Needed) – Some surfaces may require a primer to improve adhesion.

Proper Application & Maintenance Techniques

Elastomeric paint is thick and although you can use a brush, roller or sprayer, special equipment like a high-build roller may be needed for the best application.

• Use a high-build roller or sprayer for even coverage.
• Apply at least two coats for maximum protection and durability.
• Allow for proper drying time between coats, as recommended by the manufacturer.

In order to keep your home’s exterior paint coating in the best condition for the longest lasting results, there are certain maintenance steps to follow:

• Regularly inspect the surface for any cracks or damage.
• Clean the surface with mild soap and water to prevent dirt buildup.
• Reapply a fresh coat every 10-15 years, depending on exposure to harsh conditions.

Frequently Asked Questions

What are the cons of elastomeric paint?

Elastomeric paint may not be the best choice for every surface, and it may not adhere well to materials like wood or metal. In addition, elastomeric paint is a more expensive type of paint than a traditional acrylic paint choice.

Why is elastomeric paint more costly?

While elastomeric paint is more expensive upfront than standard acrylic exterior paint, its longer lifespan and reduced maintenance needs make it a cost-effective choice in the long run. Standard exterior paints may need repainting every 5-7 years, while elastomeric coatings can last 10-15 years before requiring a touch-up.

What is the difference between acrylic and elastomeric paint?

Both elastomeric and acrylic paints are popular exterior options, but they serve different purposes. Elastomeric paint is best for surfaces that require durability and water resistance, which is what makes it ideal for stucco and concrete. Acrylic paint is more breathable, which makes it suitable for a wider range of surfaces.

Can you use elastomeric paint on interior walls?

You can use elastomeric paint for interior painting if you are concerned with the area’s humidity, because of its ability to expand and contract on the applied surface. This may be best for rooms such as bathrooms, laundry rooms or basements.

Is elastomeric paint better than epoxy paint?

One is not better than the other, they are superior products that are beneficial for different surfaces. Elastomeric paint handles surface expansion and is a better choice for stucco or brick, whereas epoxy is super durable and a better choice for garage doors and floors.
