What Is Stucco Made Of?

Stucco is a special combination of cement, sand, and water. The proportions of these ingredients can vary depending on the specific application and desired finish. A typical stucco mixture might consist of:

  • Portland Cement: Portland cement is the primary binder in stucco mixtures and gives the material its strength and durability. Portland cement is made from limestone, clay, and other materials that are heated and ground into a fine powder.
  • Sand: Sand is added to the mixture to give it texture and volume. The type of sand used will depend on the desired finish and other ingredients used in the recipe.
  • Water: Water is added to the mixture to hydrate the cement and create a workable consistency.

In addition to the main ingredients of cement and sand, stucco may also include other materials such as lime and fibers, or additives to improve workability and water resistance.

How Is Stucco Applied?

Stucco is typically applied in several layers over a prepared surface, using a combination of trowels and other tools. The application of stucco typically follows these steps:

  1. Surface preparation: The surface to be covered with stucco must be clean, dry, and free of debris, loose paint, or other contaminants.
  2. Scratch coat: A base layer of stucco, called the scratch coat, is troweled onto the surface. The scratch coat is scratched with a tool to create a rough surface for the next layer to adhere to.
  3. Brown coat: The second layer of stucco, known as the brown coat, is applied over the scratch coat using a trowel. The brown coat is leveled and smoothed to create a flat surface.
  4. Finish coat: The final coat of stucco, known as the finish coat, is applied over the brown coat using a trowel or other tools. The finish coat can be textured, colored or decorated in any number of ways to achieve the desired appearance.
  5. Curing and maintenance: Once the stucco is applied, it must be allowed to cure and dry completely before painting or other finishing work can be done. It is important to follow appropriate curing times and maintenance procedures to ensure the durability and longevity of the stucco finish.

When stucco is properly applied, it creates an excellent exterior finish for buildings.
