What Is Stucco? We Explain The Details

If you’re planning a home improvement or renovation, you’ve probably come across the term “stucco” and may be wondering what it is. This construction material is used to give a structure more rigidity and durability. It is applied as a finishing coat and can be used to create a textured or smooth stucco finish.

In this article, we will discuss exterior stucco in greater detail to help you understand what it’s made of and some of the stucco types available. 

Types of Stucco Finishes

Stucco is often described as a cement-like construction material that is made using varying quantities of lime, sand, Portland cement, and water. It is usually applied in a thin layer over masonry structures and can be painted for extra durability and strength. 

This material is often applied in two or three layers. The first is a stucco scratch coat to ensure that the plaster adheres well, and the second and third are often used to achieve the desired finish. 

Here are some of the most common stucco finishes that you should consider for your home:

1. Smooth Finish 

This finish is undoubtedly the most popular among homeowners. It is preferred because smooth finish stucco is easier to clean and tends to resemble painted walls. Smooth walls are also contemporary, as they promote a sense of minimalism and can be achieved by troweling over the stucco material on the surface until it is smooth and uniform.

2. Cat Face Finish

To create this texture, a layer of stucco finish coat is applied, and a sprayer or roller is used to make “stamps” that somewhat resemble the face of a cat. This leaves you with a combination of textured and smooth areas. 

3. Sand Finish Stucco

Did you know that sand can also be mixed into concrete stucco to produce a textured appearance? Sand finish stucco can vary greatly, depending on the particle size of the sand used. The result is often a more subtle finish coat with stucco and sand. 

It’s important to remember that there are many other types of stucco finishes, so whether you are hoping to apply stucco to a roof, create visual interest with a textured stucco panel, or protect the entire exterior surface of your home, you are sure to find different types of stucco to help you reach your goals. 

We recommend exploring the many available stucco designs before choosing one for your next project. 

Stucco vs. Plaster: Which One Should You Choose? 

Stucco and plaster are two construction materials that are applied over walls and ceilings to add a layer of protection. Although cement may be seen as an alternative to stucco, there are differences you need to know about before making a choice between stucco vs. plaster: 

• Composition. Stucco uses Portland cement, lime, sand, and water, while plaster comprises either gypsum, lime, or cement and water. 
• Durability. You can expect stucco to last longer than cement, providing your home with many decades of faithful protection. 
• Application. In general, cement plaster is applied to the home’s interior surfaces, whereas stucco is used on exterior surfaces where weatherproofing is necessary. 

Can You Stucco Over Brick? 

If you have brick walls, you may be wondering, “Can you stucco over brick?” The good news is that you can. Stucco can breathe new life into an old, boring brick wall and allow you to add various textures or simply achieve a smooth stucco finish. 

You will need to make sure the brick surface is dry, clean, free of loose mortar, and wet before applying stucco over the brick. To increase adhesion, we recommend using a high-quality base coat or bonding agent.

When it comes to stucco vs. brick, there are undoubtedly benefits to choosing stucco. Brick walls are often exposed and do not have a coating to protect them from the elements. Stucco surfaces, on the other hand, are protected thanks to the resilience and durability of the stucco.

Can You Put Siding Over Stucco?

Yes, it’s possible to put siding over stucco. However, it’s important to follow the correct preparation steps, or the plaster could crumble under the weight of the siding. This is why it’s important to contact a reliable contractor for assistance. 

Keep in mind that durability is an important consideration when choosing between stucco vs. siding. Although siding may seem more cost-effective, stucco offers long-term value, so it’s probably better to fix your stucco rather than put siding over it. 

How Long Does Stucco Last?

When deciding whether to apply this finish to their walls and masonry surfaces, many homeowners ask, “How long does stucco last?” The good news is that if you correctly apply stucco on concrete and maintain it well, you can expect it to provide between 50 to 80 years of use.
