Elastomeric Paint: What is It and How Does it Work?
Elastomeric paint is a high-build, flexible coating specifically designed to withstand extreme weather conditions. Unlike traditional paints, it forms a thick, waterproof barrier on surfaces, making it ideal for stucco, masonry, and other porous materials. Its unique composition allows it to stretch and contract with the substrate, preventing cracks from spreading and protecting against water intrusion.
Key Features of Elastomeric Paint
- Waterproofing Properties: Elastomeric paint creates a seamless, watertight layer, safeguarding surfaces from moisture damage and reducing the risk of mold or mildew.
- Flexibility: The paint’s elasticity accommodates structural shifts, making it particularly useful for areas prone to temperature fluctuations or minor settling. This is especially relevant for homes in London, Ontario, where seasonal weather changes can cause structural shifts.
- High-Build Coating: Its dense, thick application provides enhanced durability, protecting against weathering and surface degradation over time.
While elastomeric paint offers impressive benefits, it also comes with challenges. Over time, improper application or substrate movement can lead to cracking in the coating. Additionally, its higher material and labor costs make it a significant investment compared to standard paints.
Understanding these aspects can help homeowners make an informed decision about whether elastomeric paint is the right solution for their exterior painting needs.

Pros of Elastomeric Paint
1. Waterproofing
Elastomeric paint provides superior waterproofing, making it an excellent choice for stucco surfaces in moist or humid climates. For homeowners in London, Ontario, where rainfall is common, this makes elastomeric paint an excellent choice. It forms a watertight seal that protects against water intrusion, preventing damage like mold, mildew, and structural weakening.
2. Density and Thickness
As a high-build coating, elastomeric paint creates a dense and durable layer. This added thickness offers better protection against environmental elements, extending the lifespan of stucco and other masonry surfaces.
3. Durability
With proper maintenance, elastomeric paint can last up to 10 years or more. Its robust formulation resists peeling, cracking, and fading, ensuring that your exterior stays vibrant and protected for a long time.
4. Flexibility
One of the key benefits of elastomeric paint is its flexibility. The paint expands and contracts with temperature changes, reducing the likelihood of cracking or damage. This feature makes it particularly suitable for areas experiencing significant seasonal weather shifts.
By choosing elastomeric paint for your stucco surfaces, you’ll enjoy a combination of durability, waterproofing, and flexibility—all critical for maintaining the integrity and appearance of your home’s exterior.
Cons of Elastomeric Paint
1. Requires Experience
Elastomeric paint demands professional application to achieve optimal results. Without the proper tools and techniques, issues like uneven finishes or insufficient adhesion can arise, compromising its performance.
2. Unclear Product Descriptions
Inconsistent quality across brands can make it difficult for homeowners to choose the right elastomeric paint. Unclear product descriptions and varying formulations add to the challenge.
3. Costly
Elastomeric paint is more expensive than standard exterior paints, both in terms of material and labor costs. Its high price can be a deterrent for budget-conscious homeowners, despite its long-term benefits.
4. Can Produce Ugly Lumps
Improper application techniques can result in unsightly lumps or uneven textures. This is particularly common if the paint is applied too thickly or without adequate surface preparation.
5. Heavy Preparation
Extensive surface preparation is required before applying elastomeric paint. This includes cleaning, sealing cracks, and sometimes priming. The additional labor can significantly increase project timelines and costs.
6. Peeling Issues
If applied incorrectly or on a poorly prepared surface, elastomeric paint may peel over time. Ensuring proper adhesion and following manufacturer guidelines is critical to prevent this problem.
7. Color Fading
Darker shades of elastomeric paint are prone to fading under intense sunlight. This can lead to uneven or dull appearances, requiring more frequent maintenance or touch-ups.
While elastomeric paint offers unique benefits, understanding these potential drawbacks can help you make a more informed decision and plan appropriately for your exterior painting project.
When and Where to Use Elastomeric Paint
Elastomeric paint is best suited for exterior surfaces that are prone to cracking, water damage, or other environmental stressors. It excels in areas with extreme weather conditions, such as heavy rainfall, intense sunlight, or frequent temperature fluctuations. In London, Ontario, where weather conditions can vary dramatically, elastomeric paint provides the necessary flexibility.
Ideal Surfaces
- Stucco: Elastomeric paint is considered the best paint for stucco due to its flexibility and waterproofing properties, which prevent cracks and water intrusion.
- Concrete Blocks: Its high-build formulation creates a durable, protective layer for concrete surfaces, safeguarding them from weathering and moisture.
- Masonry: For exterior masonry, elastomeric paint’s elasticity and adhesion ensure long-lasting protection against the elements.
When to Use Elastomeric Paint
- Extreme Weather Areas: In regions with heavy rainfall or dramatic temperature changes, elastomeric paint offers the necessary flexibility and waterproofing.
- Damaged or Cracked Surfaces: If your stucco or masonry shows signs of cracking, elastomeric paint can seal and prevent further damage.

Preparation is Key
To maximize the longevity and performance of elastomeric paint, proper surface preparation is crucial. In cities like London, Ontario, where harsh winters and wet springs can affect exterior surfaces, preparation becomes even more vital. Cleaning, sealing cracks, and priming (if necessary) help ensure optimal adhesion and durability.
By applying elastomeric paint to the right surfaces under the right conditions, homeowners can achieve a protective, long-lasting finish that stands up to environmental challenges.

Periodically clean the surface using mild soap and water to remove grime and prevent buildup. Additionally, inspect your exterior for signs of wear, such as cracks or peeling, and address these issues promptly.
Repainting After 7+ Years
While elastomeric paint is known for its durability, exposure to sunlight and weather can cause fading, especially in darker colors. Repainting stucco or masonry coated with elastomeric paint may be necessary after seven or more years to restore its vibrant appearance and protective qualities.
