The Pros & Cons of Elastomeric House Paint

Elastomeric house paint is the primary go-to exterior paint product for home builders, commercial businesses, and homeowners due to its numerous benefits. With its ability to expand and contract, this type of paint can withstand extreme weather conditions and protect your home’s exterior for years to come. However, like any other product, it also has its drawbacks. In this blog post, we will delve into the pros and cons of elastomeric paint, giving you a better understanding of its capabilities and limitations. So let’s flex our knowledge and explore the ins and outs of elastomeric house paint.

Elastomeric paint isn’t as old as other house paints. However, it is the go-to solution when you seek versatile paints that offer protection against moisture and other elements. From waterproofing to longevity, there are various benefits of using elastomeric paint, explaining its widespread use in residential and commercial exterior stucco painting projects. Elastomeric paint also has drawbacks you should be aware of before purchasing. Whether you want to paint a concrete block home or want a flexible solution for complex exterior stucco commercial painting projects, exploring the pros and cons of elastomeric paints is crucial.

Understanding Elastomeric Paint: What is It and How Does it Work?

Elastomeric paint is a flexible, high-build coating that is commonly used for residential and commercial stucco or concrete block painting projects. It is specifically designed to withstand the stresses of expansion and contraction caused by temperature fluctuations and weather conditions.

Unlike traditional paint, elastomeric paint contains a higher percentage of solids, which gives it the ability to bridge small cracks and create a waterproof barrier on surfaces like stucco and masonry. This is why it is often used for exterior applications, where waterproofing, durability and protection are crucial.

Elastomeric paint works by forming a thick, rubber-like membrane that can stretch and flex with the substrate. This helps to prevent water penetration and can help to extend the lifespan of the underlying surface. Additionally, elastomeric paint is highly resistant to cracking and peeling, making it a great choice for areas with extreme weather conditions.

While elastomeric paint offers many advantages, it also has its limitations. Despite its flexibility, elastomeric paint can still crack and fade over time, especially if exposed to harsh Jacksonville, Florida sunlight. Additionally, the cost of elastomeric paint is generally higher than traditional acrylic paint. Why does elastomeric paint cost more you might ask? Well, it’s very thick, and therefore the coverage rate compared to acrylic paint is much less. The average spread rate for an elastomeric paint is 100 feet per gal, while an acrylic spread rate is roughly 250-300 per gal on most stucco surfaces. Therefore, you will use twice the amount of paint when using elastomeric paint compared to acrylic paint.

In contrast, acrylic paint is a durable and long-lasting option that resists fading and allows the substrate to breathe. It may not have the same high-build capabilities as elastomeric paint, but it can still provide excellent protection and longevity for your home.

The Advantages of Using Elastomeric Paint on Stucco

Here are 4 Reasons For Using Elastomeric Paint

1. Waterproofing

This is perhaps the most significant advantage of elastomeric house paints. The paint offers a secure layer that moisture and water won’t penetrate. It is the ideal stucco paint and solution for anyone looking to secure concrete blocks, roofs, walls, floors, and poured concrete. However, you need a proper painting process to guarantee a watertight surface. The waterproofing properties of elastomeric paint make it ideal for surfaces exposed to rainwater damage.

2. Density/Thickness

Elastomeric paints offer ten to twenty mills per coating, which is significantly thicker than the two to three mills you get from ordinary house paint. The extra thickness translates into better protection for your walls. You can see and feel the difference in texture and toughness. The higher dry film thickness (DFT) suits surfaces exposed to harsh conditions, such as weather elements. Exterior paint density also keeps all moisture away.

3. Durability/Dependability

Elastomeric paint has a stronger composition and offers a thicker layer that outlives most paints. Most come with a lengthy warranty up to 10 years or more, especially when combined with an elastomeric coating. Ordinary paints usually feature 2-3 year warranties and rarely live that long without proper maintenance. Elastomeric paint offers the best durability making it a perfect option for stucco paint, exterior walls, and concrete block surfaces exposed to weather elements.

4. Flexible/Bendable

Elastomeric paints are above-grade, a high-build coating designed to protect masonry surfaces, mainly exterior walls, and roofs. Like other paints, Elastomeric paint is applied in liquid form. However, it hardens into a flexible, watertight hide that suits roofs. Most roof paint is elastomeric, meaning the paint can stretch and return to its original form without damage. The flexibility also makes the paint perfect for exterior walls and other surfaces exposed to heat and cold.

Disadvantages: The Possible Downside of Choosing Elastomeric Paint

While elastomeric paint offers numerous advantages, there are a few potential downsides to consider before choosing this type of paint for your home. One of the main disadvantages is that elastomeric paint can fade over time, especially when exposed to harsh sunlight. This can result in a loss of color vibrancy and may require touch-ups or repainting in the future. Additionally, elastomeric paint tends to be more expensive than traditional acrylic paint, which can be a deterrent for some homeowners on a tight budget. It’s important to weigh the cost versus the benefits before making a decision.

Another consideration is that elastomeric paint may not be suitable for every surface. While it excels at waterproofing and protecting materials like stucco and masonry, it may not adhere as well to other surfaces. This means that proper preparation and priming may be necessary to ensure proper adhesion and longevity.

In contrast, acrylic paint offers its own set of advantages. It tends to last longer and resist fading better than elastomeric paint. Additionally, acrylic paint allows the substrate to breathe, preventing moisture buildup and potential damage. So if fade resistance and breathability are major concerns for you, acrylic paint may be a more suitable choice.

Overall, it’s important to carefully consider the pros and cons before deciding on elastomeric paint for your home. While it offers excellent durability and protection, it may not be the best choice for every situation or budget. It’s always a good idea to consult with a professional to determine the best paint option for your specific needs and circumstances.

1. Requires Experience

Applying elastomeric paint requires an experienced painter who understands what is needed to achieve great results. Improper application can result in thin, weak paints that peel off. There are various considerations to make when selecting elastomeric paint, depending on the project and the surface to be painted. Preparation, primer choice, and application method all require professional insight. The thickness and properties also make elastomeric paint applications different and overwhelming for newbies.

2. Unclear Product Descriptions

Not all elastomeric house paints you encounter are desirable for your project. Quality varies across the many brands, so you should focus on reviewing the descriptions and quality before purchasing. Reliable brands include the dry film thickness, the number of application layers required, and maintenance. However, finding a comprehensive description of elastomeric paints can be daunting. You should read the warranty to determine what is covered or request further details before making an order.

3. Costly

Using elastomeric paint can increase various expenses. The paint costs up to 50% more than ordinary options, although it covers the same space, albeit thicker. You also need thorough surface preparation, which combines pressure washing with chemicals such as chlorine and borax. You will likely need a professional to take care of the surface preparation, which increases the total cost. What’s more, elastomeric paints are applied five to ten times thicker, which is laborious and costly.

4. Can Product Ugly Lumps

Elastomeric paint application calls for precautions above ordinary measures. The surface must be clean and exfoliated from other substrates that can cause bonding problems. The thinning ratio and application process also call for maximum concentration. Projects handled by amateurs often feature lumps. You need a couple of layers to achieve the required thickness, resulting in a rough finish. The ugly lumps can also form due to natural reactions or when moisture and air permeate fresh paint.

5. Heavy Preparation

Elastomeric paints have shown better results in old buildings. Most painters recommend it for older structures or a slightly worn-out concrete block. However, before applying the paint, you must remove all previous paint, grease, and substrates. Applying elastomeric paints onto other substrates can cause bonding issues, moisture penetration, and peeling. Preparation often involves using solvents, bleachers, and chemicals like borax and chlorine. You also need pressure washing tools and expertise. What’s more, you might require a primer before applying paint.

6. Peeling and Permeation

Unlike other paints, elastomeric paint won’t permeate the surface beyond the base level. If the surface has large cracks, you should repair and seal them before the paintwork. Elastomeric paint will also peel soon after the application if the paintwork isn’t as thick as required. Cutting with water also causes thinning and subsequent peeling. Because of this, elastomeric paint has limited application and doesn’t suit flat roofs and decks. However, working with experienced painters can provide flexible, waterproof layers that outlive their warranty.

7. Darker Elastomeric Paint Colors Fade Badly

Darker paint colors may look stunning initially, but they can be problematic in the long run. When it comes to exterior painting for residential and commercial properties, it’s essential to consider the durability of the chosen colors. Darker shades tend to fade faster than lighter ones, especially when exposed to sunlight. This can lead to a dull and unattractive appearance over time. To ensure long-lasting beauty for your property, consider opting for lighter paint colors that are less prone to fading. Our team at ANEWLEAF Painting can guide you in selecting the right shades that will stand the test of time.

When and Where to Use Elastomeric Paint – The Best Stucco, Block, & Concrete Paint.

When and where to use elastomeric paint is an important consideration when deciding if it is the right choice for your home. One of the primary applications for elastomeric paint is on exterior surfaces that are prone to cracking and damage, such as stucco and masonry. The high-build capabilities of elastomeric paint allow it to bridge small cracks and create a waterproof barrier, protecting your home from water damage and moisture penetration. This makes it an excellent choice for homes in areas with heavy rainfall or extreme weather conditions.

Elastomeric Paint Is Designed For Stucco and Concrete Block

However, elastomeric paint may not be suitable for every surface. It may not adhere as well to other materials, such as wood or metal, and may require proper preparation and priming to ensure proper adhesion and longevity.

In terms of cost, elastomeric paint tends to be more expensive than traditional acrylic paint. If budget is a major concern, you may want to consider acrylic paint, which also offers excellent durability and longevity. Acrylic paint is known for its fade resistance and ability to allow the substrate to breathe, preventing moisture buildup and potential damage.

Ultimately, the decision to use elastomeric paint should be based on your specific needs and circumstances. Consulting with a professional stucco painter can help determine if elastomeric paint is the best choice for your home, or if another option, such as acrylic paint, may be more suitable.

Maintaining Elastomeric Paints

If you choose elastomeric paints as your solution, the 1 to 10 years will feature scheduled maintenance to keep your paints appealing and useful. The warranty is based on the thickness and provided by the manufacturer or painting contractor. Maintenance will involve routine cleaning to remove dirt, clogging, and accumulated debris from your roof and other surfaces.

Cleaning will maintain your paint for the first three years. You should also monitor for visible damages, such as peeling, scratches, cracks, and fading color. Into the 7th year and onwards, your paint will start exposing preexisting substrates and calls for comprehensive inspection and repainting. Applying new paint over preexisting EWC is a specialized technique that requires experts.

Professional Painting Advice and Opinion About Painting Stucco And Elastomeric Paints

After 30 years in the commercial and residential painting industry and painting more than 10,000 homes and business, you learn a thing or two because you have seen a thing or two. One of my most consistent observations working with elastomeric paint is that while it is hands-down the best product for waterproofing stucco, it has real limitations that every homeowner should understand before committing to it.

The most visible drawback in Jacksonville’s climate is fading. Elastomeric coatings are not UV-stable by nature, and darker colors will typically fade badly within 4 to 6 years of application under Florida’s intense sun. This is not a rare edge case — it is something we see consistently on homes across Northeast Florida. Lighter colors hold better, but even those will chalk and dull faster than a premium acrylic latex under sustained UV exposure.

The more serious limitation is one most homeowners never consider. Elastomeric coatings are completely non-permeable — and in Jacksonville’s climate, where moisture intrusion is a constant reality, that cuts both ways. When the coating is intact it keeps water out beautifully. But any moisture that gets behind the film through cracks, gaps, or failed areas has nowhere to escape. That trapped moisture works against the substrate from the inside, accelerating the very damage the coating was meant to prevent. Homes that already carry multiple layers of old paint are also poor candidates — the additional film weight of an elastomeric coating can cause the entire paint system to pull away from the surface over time. And because elastomeric requires precise professional application, common mistakes like over-application, lap marks, and uneven texture are easy to make and difficult to fix once the product has cured.

The bottom line is this — elastomeric paint is the right tool for specific situations. For a properly prepared stucco surface with active hairline cracking and no existing paint buildup, it is the best waterproofing system available. For everything else, a premium 100% acrylic latex is usually the smarter long-term choice in Florida’s conditions.

What Can Be Done to Prevent This the Next Time You Paint?

Let’s establish a firm foundation before making any decisions about your next paint job — because getting this right will save you thousands of dollars and years of premature repainting.

1. The first one or two times you paint stucco, elastomeric is the right call. There is no better product for waterproofing raw or lightly painted stucco. All the reasons covered above apply here — elastomeric bridges hairline cracks, forms a continuous waterproof seal, and protects your home from the kind of moisture intrusion that leads to structural damage costing far more than a paint job to repair. For a first or second coat on stucco, it earns its premium price tag.

2. Know where you are in your paint cycle. If your home has been painted one or two times and it has only been 4 to 6 years since the last coat, the high-build waterproofing benefits of the elastomeric system are likely still active and working. You may not need a full elastomeric recoat — you may simply need smart targeted prep and a premium acrylic topcoat to get another strong paint cycle out of your home.

What To Do To Get the Most Value From Your Next Paint Job

1. Seal cracks strategically before you paint. If you are repainting a stucco home and it has only been 4 to 8 years since the last paint job, here is the approach we recommend. Seal and caulk all visible stucco cracks first, then apply a spot prime coat of elastomeric paint directly over those sealed cracks before your finish coat goes on. You are not recoating the entire home in elastomeric — you are using it surgically where it does its best work, adding a targeted layer of waterproofing protection at every crack and penetration point before the premium acrylic topcoat goes on over everything.

2. Make the color switch — lighter is smarter on stucco. If your current home color is medium to dark, this is the single most impactful decision you can make for your next paint cycle. Darker colors on elastomeric-coated stucco fade badly and fast under Jacksonville’s UV. A lighter color will hold its vibrancy significantly longer, look cleaner between paint cycles, and reduce the surface temperature of your stucco walls — which reduces thermal expansion and the cracking that comes with it. This is not just an aesthetic recommendation. In Florida’s climate, lighter colors on stucco are a practical protection decision.

3. Repaint with the best premium acrylic you can afford. Once cracks are sealed, spot-primed, and your color is selected, finish the job with a top-tier 100% acrylic latex exterior paint — Sherwin-Williams Emerald Exterior or Benjamin Moore Aura Exterior are the two products we specify on Jacksonville stucco homes in this situation. Premium acrylic resists UV fading significantly better than elastomeric, applies more smoothly, and gives you a finish that will hold its color and integrity for 8 to 12 years in Florida’s conditions when properly applied. Do not cut corners on product selection at this stage — the difference between a premium acrylic and a mid-grade product is measured in years of paint life, not months.

How to Paint Over Elastomeric Paint

Painting over an existing elastomeric coating requires a specific approach — you cannot simply roll standard acrylic paint over a thick elastomeric film and expect it to bond correctly. The surface needs to be properly cleaned, any failed or peeling areas need to be addressed, and the right primer system needs to be used to ensure adhesion between the old elastomeric film and the new topcoat. Skipping these steps is one of the most common reasons repaint jobs on stucco homes fail within two to three years of application.

Professional Elastomeric Painting for Your Home

There are several merits and demerits to using elastomeric paints. These options are provided for unique applications, mainly those requiring better protection from the elements. It is essential to choose trusted contractors that can provide premium quality paint and services. Quality results call for experienced professionals. It is also the only way to preserve your warranty.
