Stucco
There are several types of stucco commonly used in construction:
Traditional or Portland cement stucco:
This is the most common type, consisting of cement, sand, and water. It's applied in multiple coats over a metal or wood lath base.
Synthetic stucco (EIFS):
This type uses synthetic materials such as polymers and foam insulation board. It's applied in layers, typically with a base coat, mesh reinforcement, and a finish coat.
Exterior Insulation and Finish System (EIFS):
This is a type of synthetic stucco that includes insulation board and a base coat applied over it, followed by a textured finish coat.
Acrylic stucco:
Made with acrylic polymers, this type offers increased flexibility and resistance to cracking. It's typically applied in two or three coats over a substrate.
Installation Methods for Different Types of Stucco
Installation methods vary depending on the type of stucco:
- Traditional Cement Stucco:
The process involves preparing the surface, applying metal lath, then applying multiple coats of stucco mixture, allowing each coat to dry before applying the next. - Synthetic Stucco:
Installed similarly to traditional stucco but may require different types of base coats and mesh reinforcement. - EIFS (Exterior Insulation and Finish System):
Involves attaching insulation board to the substrate, applying a base coat with mesh reinforcement, and finishing with a textured topcoat. - Acrylic Stucco:
Typically applied similarly to traditional stucco but with acrylic-based materials, offering increased flexibility and durability.
