Which of the following describes a benefit of using a two-coat stucco application?

A two-coat stucco application is beneficial due to the enhanced adhesion and finish it provides. This method involves applying a scratch coat and then a brown coat before the final finish coat is added. The scratch coat creates a textured surface that grips the subsequent layers, leading to a stronger bond overall. Additionally, the two layers help to create a more uniform and polished finish compared to a single coat.

The improvement in adhesion reduces the risk of cracking or peeling over time, making the stucco more durable and long-lasting. Such an application is crucial, especially in areas with varying temperatures and humidity, as it better accommodates expansion and contraction. This technique is widely recognized in the construction industry for producing superior results when compared to single-layer applications.

In contrast, while improved insulation, faster drying time, and lower material costs are considerations in stucco application, they do not directly stem from the two-coat method as fundamentally as adhesion and finish quality do.
