What is a characteristic of stucco cement?

Stucco cement is characterized by a traditional three-coat installation process, which is essential for creating a durable and weather-resistant exterior finish. The first coat, known as the scratch coat, is applied directly to the substrate to provide a base that supports the subsequent layers. After the scratch coat is properly cured, a second coat, often referred to as the brown coat, is applied to create a smoother surface. Finally, a finish coat, sometimes called the colored coat, is added to enhance the aesthetics and provide additional protection against the elements. This layered approach is fundamental in stucco application, as it allows for better adhesion, improved strength, and enhanced weather resistance. The three-coat method is a widely accepted industry standard for achieving the best performance and longevity in stucco installations.

The other options do not accurately reflect the established practices in stucco application. Single coat applications may be suitable for certain products but are not representative of traditional stucco practices. One layer of plaster oversimplifies the application process and overlooks the necessary layering for proper function. Lastly, while stucco can be applied over various surfaces, it is not limited to wooden surfaces, as it can also be applied over concrete, brick, and other materials.
