The Pros & Cons of Elastomeric House Paint

The Pros & Cons 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 painting projects. The exterior 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 commercial painting projects, exploring the pros and cons of elastomeric house paints is crucial.

What is Elastomeric Paint?

Elastomeric paint is a high-build coating and it's designed waterproof stucco and masonry. This coating is flexible, expands, and contracts, bridging hairline cracks in vertical masonry surfaces. Elastomeric paint is extremely durable against mildew and dirt and is a very resistant waterproofing finish that has superior elasticity and elongation properties to resist cracking. Elastomeric paint is designed for the use of masonry and concrete construction to prevent water from penetrating into building interiors. The flexible film covers and hides hairline cracks, making uniform pinhole-free jobs easier and faster to achieve.

The Advantages of Using Elastomeric Paint on Stucco

The primary purpose of elastomeric paint is to form a waterproof protection barrier against any form of moisture. Elastomeric paint is a high build coating that is designed to protect and waterproof stucco and masonry surfaces. These coatings help protect your stucco from wind-driven rain and can create a waterproofing system that protects your stucco if applied correctly.

Here are 4 Reason 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 damages.

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 the original form without damage. The flexibility also makes the paint perfect for exterior walls and other surfaces exposed to heat and cold.

Main Disadvantages

Here are the top cons of using elastomeric house paints:

1. Requires Experience

Applying elastomeric paint requires an experienced painter that 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 surface to be painted. Preparation, primer choice, and application method all require professional insight. The thickness and properties also make elastomeric paint application 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, 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 of other substrates that can cause bonding problems. The thinning ratio and application process also calls 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 our 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.

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.
