The Second Coat in a 3-Coat Stucco System

What is the second coat in a 3-coat stucco system called?

a) Scratch coat

b) Finish coat

c) Brown coat

d) Base coat

Answer:

In a 3-coat stucco system, the second coat is called the Brown coat.

The second coat in a 3-coat stucco system is known as the Brown coat. This coat comes after the Scratch coat and before the Finish coat in the application process. Despite the term "Base coat" being commonly used for the first coat in other paint systems, in a 3-coat stucco system, the Base coat actually refers to the combined Scratch and Brown coats.

The order of application in a 3-coat stucco system is as follows: Scratch coat, Brown coat, and Finish coat. The Scratch coat serves as the initial layer, providing a base for the subsequent coats. Following the Scratch coat, the Brown coat is applied to add thickness and strength to the stucco system. Finally, the Finish coat is the last layer that offers the desired texture and appearance to the surface.

Understanding the terminology and sequence of coats is crucial in achieving a successful 3-coat stucco system application. Each coat plays a specific role in enhancing the durability, aesthetics, and overall performance of the stucco finish.
