What Is Stucco?

​Before we get to the ins and outs of the stucco system, it’s important to first answer the question, “What is stucco?” As part of this stucco definition, we will also explain the role it plays in masonry construction. 

Stucco is a kind of plaster that’s applied in thin layers to weatherproof and protect the underlying structure. It is often the material of choice for exterior surfaces. Another question we often hear is, “What is stucco made of?” This durable finishing material is created using a mixture of lime, Portland cement, sand, and water.  

What Are the Steps for Stucco? 

What Are the Steps for Stucco? 

At this point, you might be asking, “What are the steps for stucco?” Without further ado, let’s get into it!

Stucco Foundation

1. Lath

The first step involved in applying stucco to a wall is installing the lath. A lath, by definition, is a kind of foundation for the stucco to adhere to. During this part of the process, special weather-resistant paper, wire mesh, and more are added to the surface. 

It’s important to remember that you may be required to have your stucco foundation inspected, depending on the local building codes in your area, so it’s important to check those before you start to lath the area. 

2. Scratch Coat

When building stucco homes, installing an initial layer of cement stucco is essential. This stucco scratch coat covers the lath to hide any imperfections and improve the adherence of the material to the walls. Once the scratch coat has been installed, it must cure completely. 

3. Curing

Next, you will need to give the structure enough time to cure. The amount of time needed for this step will ultimately depend on the size of your stucco home.

4. Brown Coat

The application of a brown coat for stucco walls signifies the end of the foundation phase. This brown coat has earned its name from its appearance. Because it comprises primarily cement and sand, the brown stucco appears brown in color. 

The Finishing Touches

Once the brown coat has been applied, it’s time to add the finishing touches. You have a number of options to finish your walls. After all, no one wants to end up with a brown stucco house. You can choose to apply a color coat stucco as one of your options. To create a black stucco house, you can use a special black stucco to smooth over the walls. 

Another option if you don’t like the idea of smooth walls is to apply a texture. A contractor will use spray guns, trowels, and more to create various types of stucco textures. You can choose one that best meets your preferences for style and visual appeal.

You can also add a stucco color coat of paint for additional protection. 

Whether you choose black stucco or a textured look, you can turn to a local masonry expert for guidance and assistance!

Stuccoing Over Wood: Is It Recommended?

​Although you might be tempted to apply stucco on wood, we definitely do not recommend it. Stuccoing over wood can lead to the degradation of the material over time, as wood tends to expand and contact over time. 

How Long Does Stucco Last?

​Stucco is a durable and long-lasting material, but ultimately, the longevity of your walls will depend on the level of care you provide them, in addition to various other factors, such as the weather conditions they are exposed to. In general, stucco lasts between 50 and 80 years. 

How Long Does Stucco Take to Dry?

​The drying time will vary from one project to another, so it’s generally best to consult your contractor for a more realistic timeframe. 

How Many Coats of Stucco Go on a House?

In addition to the foundation for stucco, two to three coats are applied, but again, this will depend on the details of the project.
