One Coat Stucco Systems
The one-coat stucco system, often misunderstood as a simplistic alternative to the traditional three-coat stucco system, encompasses a multi-layered approach. This system, while sharing similarities with its three-coat counterparts, differs in several key aspects, making it a unique and efficient option in the world of stucco finishes.
Understanding the One Coat Stucco System
A one coat stucco system comprises:
- The Lath Coat:
- Components: Incorporates water-resistant paper, 1″ foam, and wire.
- Function: The lath coat serves as the foundation, providing water resistance and structural integrity.
- The Brown Coat:
- Description: A leveling base coat applied over the lath.
- Role: This layer acts as the substrate for the finish coat, ensuring a smooth and even application.
- The Finish Coat:
- Characteristics: A colored and textured final layer.
- Importance: This coat not only adds aesthetic appeal but also protects the underlying layers.
Misconceptions and Clarifications
Despite its name, the one coat stucco system involves more than a single layer. Commonly misconceived as a two-coat system, it includes a base and finish coat. Industry professionals, however, consistently refer to it as a “one coat stucco system.”
Detailed Analysis of Each Layer
- The Lath Coat:
- Composition: Features asphalt-infused paper (in two plies), EPS insulating foam, and a 20-gauge wire.
- Purpose: Provides waterproofing and acts as a base for subsequent layers.
- The Brown Coat:
- Composition: A special mix including cement, sand, lime, fiberglass strands, and other proprietary components.
- Function: Offers a strong and even base for the finish coat.
- The Finish Coat:
- Variety: Available in numerous textures and colors, providing versatility in design.
- Application: Applied at a thickness of 1/8″, often in a single coat.
Application Process
The one-coat stucco system can be applied manually or sprayed on, depending on the scale of the project.
- Mixing Materials: Utilizes a mix of traditional and modern techniques for preparing stucco.
- Applying by Hand: Involves the use of a hock and trowel for precise application.
- Spraying Technique: Preferred by larger companies for its efficiency in covering extensive areas rapidly.
Curing Times
- Base Coat: Typically requires a 7-day curing period.
- Finish Coat: Varies from a few days for acrylic finishes to up to 28-days for cement-based finishes.
