What Is Stucco?

Stucco is a versatile and durable exterior material that has been used in residential homes for centuries. Originally derived from ancient building techniques, stucco was favored by civilizations such as the Romans and Greeks, who used lime-based plaster to coat their walls. Over time, this material evolved, incorporating cement and other additives to improve its strength and longevity. 

Today, it is known for its ability to withstand harsh climates, making it particularly popular in regions like Southern Arizona, where extreme heat and occasional rain storms are common.

Traditional stucco is made from a mixture of sand, cement, lime, and water, which is applied to walls in layers to create a hard, durable surface. It has been a staple in home construction due to its affordability, adaptability, and resistance to fire and moisture.

On the other hand, synthetic stucco, known as EIFS (Exterior Insulation and Finish System), is a more modern version. Developed in Europe after World War II and introduced in the U.S. in the 1960s, EIFS quickly gained popularity for its energy efficiency. Unlike traditional stucco, EIFS incorporates an insulating layer of foam, which helps homes retain heat in the winter and stay cool during the summer​.

In modern construction, both traditional and synthetic stucco are widely used. Traditional stucco is prized for its thick, protective qualities and ability to resist damage, while EIFS provides superior insulation and flexibility.

Understanding the differences between these two types of stucco can help homeowners make informed decisions about which material is best for their home.

Types of Stucco for Residential Homes

Traditional Stucco

Traditional stucco, also referred to as “hard-coat stucco,” has been used for centuries in various architectural styles. From Spanish missions to Mediterranean homes, traditional stucco is especially common in arid climates like Southern Arizona due to its natural resistance to heat and its ability to maintain a home’s cool interior​.

One of the primary advantages of traditional stucco is its durability. Applied in layers (often three), it forms a thick, protective barrier over a home’s exterior that can last for 50 years or more with minimal maintenance​. It also offers homeowners flexibility in design, with the option to choose from various textures, from smooth finishes to more rustic, textured appearances.

However, traditional stucco does have limitations. While it is generally resistant to fire, it is prone to cracking, especially in areas with shifting soil or seismic activity. For example, homes built on foundations that settle or shift over time may see cracks appear in their stucco, requiring regular maintenance​.

Synthetic Stucco (EIFS)

EIFS, which stands for Exterior Insulation and Finish System, is a more recent development in stucco technology. Unlike traditional stucco, EIFS includes a foam insulation board as part of the system, which provides improved energy efficiency. This insulating layer makes EIFS particularly appealing for homeowners looking to reduce their energy costs, as it helps to maintain interior temperatures more effectively​.

Another key advantage of EIFS is its flexibility. The material is more resistant to cracking than traditional stucco because it is lighter and has some elasticity, allowing it to “move” with the structure of the home without cracking as easily​.

However, EIFS has faced some criticism for its vulnerability to water damage if not installed properly. Early versions of EIFS lacked proper drainage systems, which led to moisture becoming trapped behind the stucco, causing mold and structural damage. Modern EIFS systems have addressed these issues with the addition of water-resistant barriers and drainage channels to prevent moisture from getting trapped behind the wall​.

While traditional stucco may be a better option for homeowners focused on durability and classic aesthetics, EIFS is ideal for those prioritizing energy efficiency and insulation. For more information on which type of stucco might be best for your home, visit our Stucco Texture Guide.

The Stucco Installation Process

Installing stucco is a labor-intensive process that requires expertise and attention to detail to ensure the material performs well over time. The process varies slightly between traditional stucco and EIFS, but both require a multi-layered approach to create a durable finish.

Traditional Stucco Installation

1. Surface Preparation:

Before applying stucco, the exterior surface must be prepared. For wood-frame homes, this usually involves attaching a metal lath, which acts as a framework for the stucco to adhere to. Homes made of masonry (such as brick or concrete) can often receive stucco directly without the need for lath​​.

2. Scratch Coat:

The first layer, called the scratch coat, is applied directly to the lath or masonry. This base coat is about 3/8 of an inch thick and is grooved to provide a textured surface for the next layer to adhere to. After the scratch coat is applied, it needs time to cure, which can take anywhere from 48 hours to a few days depending on weather conditions​.

3. Brown Coat:

The brown coat is the second layer of stucco, applied after the scratch coat has dried. This coat is thicker and provides additional strength. It is smoothed to create a flat, even surface for the finish coat. Like the scratch coat, the brown coat must cure before the finish coat is applied​.

4. Finish Coat:

The final layer is the finish coat, which determines the texture and appearance of the stucco. This layer can be customized to achieve a smooth, rough, or patterned texture depending on the homeowner’s preference. The finish coat also includes color pigments if the homeowner desires a specific hue​​.

Synthetic Stucco Installation (EIFS)

The installation of EIFS is similar in some ways to traditional stucco but with key differences due to the inclusion of insulation.

1. Insulation Board Installation:

The first step in installing EIFS is attaching a foam insulation board to the home’s exterior. This board is adhered to the wall and serves as a base layer that provides energy efficiency​.

2. Base Coat Application:

A base coat is applied over the insulation board, embedding a fiberglass mesh into the base coat to reinforce the system. This layer provides strength and acts as a weather barrier​.

3. Finish Coat:

The final layer is an acrylic-based finish coat, which is applied over the base coat. Like traditional stucco, the finish coat can be customized with different textures and colors​.

Pros and Cons of Residential Stucco

When considering stucco for your home, it’s important to weigh the advantages and disadvantages. While stucco has long been favored for its durability and classic aesthetic, there are some potential downsides that homeowners should be aware of.

Pros of Stucco:

• Durability and Longevity: Traditional stucco can last up to 50 years or more when properly installed and maintained. It is highly resistant to fire, insects, and the wear and tear of everyday weather, which makes it ideal for homes in the hot, dry climates of Southern Arizona​. When cracks do appear, they are often superficial and can be easily repaired.

• Energy Efficiency: With the development of EIFS, stucco now offers enhanced energy efficiency. The foam insulation used in EIFS helps to reduce heat transfer, keeping homes cooler in summer and reducing energy costs. In a desert climate like Tucson’s, this can make a significant difference in your monthly utility bills​.

• Low Maintenance: One of the biggest advantages of stucco is its low maintenance requirements. Unlike wood siding, stucco does not need to be painted regularly, and it’s resistant to pests like termites. Occasional cleaning and small repairs will keep your stucco looking great for decades​​.

• Aesthetic Flexibility: Stucco comes in a wide range of textures and colors, making it easy to customize the look of your home’s exterior. From smooth, modern finishes to rough, rustic textures, stucco can be tailored to fit any architectural style​.

Cons of Stucco:

• Vulnerability to Water Damage: Stucco, particularly EIFS, can be vulnerable to water damage if not installed correctly. If moisture gets trapped behind the stucco, it can lead to mold, mildew, and structural damage. Proper installation, including the use of drainage systems and moisture barriers, is essential to preventing these issues​.

• Cracking in Extreme Conditions: While stucco is durable, it can crack in areas with significant temperature fluctuations or shifting foundations. Regular stucco inspections and prompt repairs are important to maintaining the integrity of the stucco​.

• Higher Upfront Costs: Compared to other siding materials, such as vinyl or wood, stucco can have a higher upfront cost. However, its longevity and low maintenance requirements often make it more cost-effective in the long run​.

While stucco has some challenges, working with an experienced contractor can ensure a smooth installation that minimizes these risks. For professional stucco installation or repair, contact Sunset Coatings Stucco & Paint to get started.

Maintaining Your Stucco Home Exterior

Maintaining a stucco exterior is relatively simple, but there are a few steps homeowners should take to ensure their stucco remains in top condition. By performing regular inspections and addressing any issues early, you can prevent small problems from turning into costly repairs.

1. Regular Inspections

It’s important to inspect your stucco regularly for signs of cracking, chipping, or water damage. Minor cracks are common in stucco, especially in hot climates like Arizona, but they should be repaired promptly to prevent moisture from seeping in. Hairline cracks can often be sealed with a high-quality caulk, while larger cracks may require professional repair.

2. Sealants and Coatings

Applying a protective sealant to your stucco can help it resist moisture, especially in areas that experience heavy rain or high humidity. However, it’s important to avoid sealants that prevent the stucco from “breathing.” Stucco is designed to allow moisture to evaporate from the surface, so choosing the right sealant is critical.

Some homeowners also opt to apply a paint or coating over the stucco. If you choose to paint, make sure the surface is clean and dry before application, and use a high-quality acrylic paint that will adhere properly to the stucco surface.

3. Routine Cleaning

Over time, dirt and dust can accumulate on stucco, especially in dry, desert climates like Tucson’s. Routine cleaning can help maintain the stucco’s appearance. A low-pressure wash is usually sufficient to remove surface dirt, but avoid using high-pressure washers, which can damage the finish.

4. Repainting or Retexturing

If your stucco begins to look worn or faded, you may consider repainting or retexturing it. Newer stucco finishes, particularly acrylic-based ones, hold color well and do not require frequent repainting. If you want to change the look of your home, retexturing can give your stucco a fresh new appearance without the need for a full replacement.
