Revolutionary Elastomeric Paint Technology Shields San Diego County Stucco Homes from Earthquake-Induced Cracking
San Diego County homeowners are discovering a game-changing solution to protect their stucco exteriors from the inevitable stress of seismic activity. 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.
The Seismic Reality of San Diego County
While many San Diego residents focus on wildfire preparedness, residents of the San Diego Area are far more susceptible to earthquake damage than most think. A major earthquake along the length of the Rose Canyon Fault could result in devastating consequences. Most residents are less than 15 miles from the fault and ground shaking from a major event is sure to cause damage throughout the county. The entire County is within Seismic Zone 4 and is subject to seismic ground shaking.
The vulnerability of San Diego’s housing stock is particularly concerning. More than 53 percent of the housing units in San Diego County fall into that category of being built before 1980 and could be in need of an earthquake retrofit in San Diego. At least 11 percent of the housing structures in the city of San Diego and 7 percent in San Diego County were built before 1950, making them particularly vulnerable.
How Elastomeric Paint Creates a Protective Barrier
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. 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.
The science behind elastomeric coatings is impressive. Tec-Top Elastomeric is a textured 100% acrylic water-based flexible 215% elongation breathable coating ideal for interior or exterior applications. This extraordinary flexibility means the paint can stretch more than double its original length without breaking, making it perfect for structures that experience movement during seismic events.
Superior Performance in Extreme Conditions
An exterior, flexible high-build coating designed to expand & contract, bridging hairline cracks in vertical masonry surfaces. This extremely durable, mildew & dirt resistant waterproofing finish has superior elasticity & elongation properties to resist cracking. It withstands 98 mph wind-driven rain.
The durability advantages are significant for homeowners. 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.
Critical Protection for Stucco Homes
For San Diego County’s abundant stucco homes, elastomeric paint offers essential protection. Stucco and masonry structures expand and contract in response to the weather and structural stresses. With Flex Right™ Technology, this paint is formulated to flex with changes in temperature to resist cracking and peeling of the film.
The first and possibly the second time you paint stucco, it’s critical to use an elastomeric paint. It waterproofs your stucco and prevents water intrusion. This is critical to protect your home from serious water intrusion damages that can cause significant unwanted structural damage that will cost a small fortune to repair.
Professional Application Considerations
Proper application of elastomeric coatings requires expertise and attention to detail. Apply using a high quality 1 1/4″ nap roller, nylon/polyester brush or airless sprayer (.025″-.029″ spray tip). A second coat must be applied at the same spread rate as the first. Professional contractors experienced in painting San Diego County, CA understand these technical requirements and can ensure optimal performance.
As a textured high build coating, it is ideal to fill in many surface imperfections and bridge small cracks. Designed to be used on concrete, stucco, masonry, plaster, and tilt-up application, Tec-Top Elastomeric exhibits excellent UV resistance, color retention and adhesion to concrete and masonry substrates.
Investment in Long-Term Protection
While elastomeric paint represents a higher initial investment than traditional paint, the long-term benefits are substantial. Elastomeric paint offers the best durability making it a perfect option for stucco paint, exterior walls, and concrete block surfaces exposed to weather elements. The 100% acrylic latex formula provides a breathable film, releasing moisture that builds in walls.
Given San Diego County’s seismic reality and the vulnerability of older housing stock, elastomeric paint represents a proactive approach to home protection. Additionally, elastomeric paint is highly resistant to cracking and peeling, making it a great choice for areas with extreme weather conditions.
The Future of Seismic-Resistant Home Protection
As building science advances and our understanding of seismic risks improves, elastomeric paint technology continues to evolve. For San Diego County homeowners, this flexible coating system offers peace of mind, knowing their stucco exteriors can withstand both daily thermal cycling and the sudden stresses of seismic activity.
The elastomeric paint revolution represents more than just a coating upgrade—it’s a comprehensive approach to protecting one of your most significant investments. With proper application by experienced professionals, these advanced coatings provide a resilient barrier that moves with your home, preventing the crack formation that can lead to costly water damage and structural issues.
