Everything You Need to Know About Residential Stucco

Stucco is a type of plaster that is commonly used as a durable and decorative coating on the exterior and interior walls of residential buildings. It is made by combining Portland cement, sand, and water to create a mixture that can be applied in multiple layers. Stucco can be finished in a variety of ways to achieve different looks and textures. Stucco is a popular choice for both residential and commercial buildings because of its versatility, durability, and aesthetic appeal.

Main types of Stucco

Two main types of stucco are as follows.

Traditional Stucco: 

This type of stucco is made from a mixture of Portland cement, sand, and water. It is applied in multiple layers over a wire mesh or lath to create a hard, durable, attractive surface. Traditional stucco can be used on both interior and exterior surfaces and is usually applied in three layers: the scratch coat, the brown coat, and the finish coat.

Synthetic Stucco: 

Synthetic stucco is also known as Exterior Insulation and Finish System (EIFS). Synthetic stucco is made from foam board insulation covered with a fiberglass mesh and a cement-like coating. It is used primarily on exterior surfaces and provides excellent insulation. Synthetic stucco can be made to mimic the look of traditional stucco, but it is generally lighter and easier to install. However, synthetic stucco is not as breathable as traditional stucco and can lead to moisture problems if not installed properly.

Further types of stucco

In addition to the two main types of stucco (traditional and synthetic), several other types of stucco are used for specific applications. Here are some further types of stucco:

Acrylic Stucco: 

This type of stucco is made from a mixture of acrylic resins, sand, and water. Acrylic stucco is very flexible, which makes it ideal for use in areas with a lot of movement or vibration. It is also resistant to cracking, fading, and chalking.

Venetian Plaster: 

This is a type of stucco that is made from a mixture of marble dust, lime, and water. Venetian plaster has a unique, glossy finish and can be tinted in a variety of colors. It is often used on interior surfaces such as walls and ceilings.

Lime Stucco: 

This is an ancient type of stucco that has been used for centuries. Lime stucco is made from lime, sand, and water and is very breathable, which makes it ideal for use on historic buildings or structures with a lot of moisture.

Elastomeric Stucco: 

This is a type of stucco that is made from a mixture of acrylic resins and synthetic polymers. It is resistant to cracking, fading, and chalking. Elastomeric paint is a high-build coating that is designed to protect masonry surfaces.  These coatings help protect your stucco from wind-driven rain and create a waterproof system if applied correctly.

Cement Stucco: 

This type of stucco is made from a mixture of cement, sand, and water. It is similar to traditional stucco but is often used on industrial or commercial buildings because of its durability.

One-Coat Stucco: 

This is a type of stucco that combines the scratch coat, brown coat, and finish coat into a single layer. It is faster and easier to apply than traditional stucco, but it is not as durable. It is a blend of Portland cement, sand, fibers, special proprietary chemicals, and water.

Finishing techniques for stucco

The finishing technique used for stucco can greatly impact the look and feel of a building, so it's important to consider the desired aesthetic when selecting a finish. Here are some common finishing techniques for stucco:

Smooth Finish: 

This is a classic finish for stucco and is achieved by troweling the final coat of stucco to create a smooth, flat surface. A smooth stucco finish, also known as a fine cement-based finish, is one of the most difficult textures to achieve. It is also the most popular among homeowners because it's easiest to clean and offers a finish closest to looking like a painted home.

Sand Finish: 

This finish is achieved by adding sand to the final coat of stucco, which creates a rougher texture. It gives buildings a sandy, textured look that is beautiful yet simple. This type of stucco is also known as “float finish” because of the floating tool typically used to apply it.

Dash Finish: 

Dash stucco finish applications create a gravely, gritty, bumpy look in a range of textures from light to dense. To achieve a unique texture, you can add shells, fine gravel, or pebbles to the mix. This texture can be applied by hand (for smaller areas) or sprayed on (using a small hopper gun). Two to three coats are usually applied in order to achieve a uniform coat.

Cat Face Finish: 

This finish is achieved by troweling the final coat of stucco to create a smooth surface, then using a stiff-bristled brush to remove some of the stucco in a pattern that creates a textured look.

Conclusion:

Stucco is a popular building material that has been used for centuries due to its versatility, durability, and aesthetic appeal. Stucco can be applied in various ways and finished to achieve different looks and textures.
