Stucco is one of the most versatile and durable building materials you can find. As a plaster-like material, it’s been used for centuries to enhance both the aesthetic and structural integrity of buildings. Whether you’re building a new home or renovating an existing one, stucco offers numerous benefits.
Nearly 25 percent of single-family homes built today feature stucco siding, according to a 2024 report from the Stucco Manufacturers Association. It ranks as the second-most popular siding in the U.S. behind vinyl. Here’s why it’s a top choice for so many homeowners.
Stucco is a cement-like product that is applied to exterior buildings in layers about 1 inch thick. It can range in roughness from smooth to textured, depending on how it is applied. Stucco is typically mixed with cement, sand, lime, and water to create a thick, durable coating that is often used on the exterior of buildings.
There are newer stucco systems that address cracking and other issues that can occur with stucco. (See Why Use Stucco below.) These offer more options for texture.
Newer stucco systems include:
Stucco provides a protective and decorative finish, but it is especially known for its strength and versatility in outdoor environments. Whether you are building a new home or restoring an old structure, stucco is a beautiful and practical choice, it is a long-lasting stucco building material that helps the building withstand the elements while maintaining its visual appeal.
In summary, while stucco offers impressive durability, aesthetic flexibility, and fire resistance, it does require proper installation and maintenance to avoid cracks and staining. With modern advancements, however, many of the traditional drawbacks have been mitigated, making it a strong choice for many homeowners.
Applying stucco requires a systematic approach to ensure both durability and aesthetic appeal. Typically, stucco is applied over a base of house wrap or felt paper and lath, which provides a stable surface for the stucco to adhere to. To further enhance the performance of your stucco system, incorporating fiberglass mesh can offer additional crack resistance and long-term durability. These materials improve the overall stability of the stucco, making it more resilient against external forces. The process generally involves three main coats, each serving a specific purpose.
For newer stucco systems, the application process can vary depending on the product used. For example, crack suppression systems require four coats, while insulating stucco systems involve several additional steps. According to Russ Grassa of S.G. Plastering in El Cajon, California, these systems typically include a polystyrene foam board, followed by fiberglass mesh, and finally, an acrylic finish coat.
In all cases, stucco is carefully applied by hand using a trowel, ensuring the layers are smooth, even, and well-adhered. The inclusion of fiberglass mesh or fiberglass fabric at various stages of the application process ensures that the stucco system not only provides a beautiful finish but also long-lasting protection for your home or building.
Maintaining stucco is essential for preserving its durability and appearance. While stucco is a resilient building material, proper care is still required to keep it in top shape. Here are a few tips for taking care of stucco and ensuring it lasts for years:
By following these steps, you can maintain the integrity of your stucco and ensure that it continues to perform well and look great for many years. Regular attention to the details will keep your stucco exterior looking fresh and functional, protecting both the aesthetics and the structure of your home.
FAQ Section: Everything You Need to Know About Stucco
Synthetic stucco, often referred to as EIFS (Exterior Insulation and Finish System), incorporates foam insulation boards beneath the stucco layers. This makes it lighter and more energy-efficient, as it offers better insulation. However, synthetic stucco is more prone to moisture issues if not properly maintained, as water can get trapped between the layers.
The main differences lie in insulation and moisture resistance. Traditional stucco tends to be more durable over time, while synthetic stucco offers improved energy efficiency but requires more attention to moisture management.
