Support:
Stucco wire lath provides a solid base for stucco plaster. It supports the heavy plaster and stops it from cracking or falling off. The wire lath helps the stucco stay attached to the building for many years.
Drainage:
The spaces between the wires allow water to move freely. If water gets behind the stucco, the lath lets it run down and escape. This prevents moisture from getting trapped, which could cause mold or rot. The drainage system helps keep the walls dry and healthy.
Ventilation:
The gaps in the wire lath also permit air circulation. Good airflow behind the stucco walls prevents dampness and reduces the risk of bacterial growth. The ventilation feature keeps the wall assembly cool and prevents heat buildup.
Separation:
Wire lath creates a gap between the stucco and the building materials, such as sheathing or plywood. This space is called a pressure relief cavity. It stops moisture from directly touching the other materials, which could cause problems over time. The cavity helps manage water and reduces pressure on the wall.
Flexibility:
The lath can bend and mold to different shapes. This allows stucco to be applied to rounded or curved surfaces, giving designers more options. The flexible wire lath accommodates unique architectural features.
Patchability:
If parts of the stucco ever get damaged, the wire lath allows for easy repairs. The same lath can be used to fix holes or cracks without needing new materials. This saves time and money on maintenance.
Compatibility:
Wire lath works well with different types of stucco mixtures, like traditional and synthetic stucco. It provides an excellent surface for all kinds of plaster applications. The lath is versatile and suitable for many stucco projects.
Rust resistance:
Galvanized steel wire lath is coated to prevent rust. It can withstand moisture and last a long time without deteriorating. The corrosion-resistant feature extends the wire lath's lifespan behind the stucco walls.
The use of wire lath for stucco is widely used in construction industries. It provides a solid base for stucco applications. It is used in residential and commercial construction projects. Below are some of the application scenarios of wire lath.
Exterior Stucco Applications
Wire lath is used as a base for stucco on exterior walls. It is galvanized to prevent rusting. The galvanized wire lath provides a solid base for stucco to grip onto. The stucco forms a durable, weather-resistant skin over wire lath. Wire lath is also used for soffits. Soffits are the underside of eaves or overhangs. Wire lath provides a continuous, smooth surface for stucco application on soffits.
Interior Stucco Applications
Interiors of residential or commercial buildings use wire lath for stucco. It provides a solid base for stucco in interior applications. It is used in interior walls and ceilings. Wire lath enhances the aesthetics of interior ceilings and walls. It is also used in fireplaces. Wire lath creates a heat-resistant, durable, and fire-resistant surface around fireplaces.
Architectural Elements
Wire lath is used in construction of architectural elements. It is used in construction of decorative archways. Wire lath creates a strong and stable base for stucco to adhere to. It is also used in construction of columns. Wire lath allows the creation of continuous stucco surfaces around column forms. Additionally, wire lath is used in construction of cornices. It provides a solid base for intricate decorative cornice shapes.
Reinforcement
Wire lath is used in reinforcement of stucco in high-stress areas. It is used in reinforcement of stucco around windows and doors. The galvanized wire lath helps to prevent cracking and damage. It provides reinforcement in areas where openings create stress points. It is also used in reinforcement of stucco at corners. Wire lath creates a strong and stable base for corners, preventing chipping or flaking.
Backer for Non-Stucco Finishes
Wire lath can be used as a backer for non-stucco finishes. These includes tile, stone veneer, and plaster. Wire lath provides a stable and strong base for attachment of heavy materials. It distributes weight evenly and prevents cracking or breaking. It also allows for easy installation of tile, plaster, and stone veneer by providing a textured surface for adhesion.
When choosing lath for stucco, there are a few factors that wholesalers should consider. Here are some of them:
Environment
The environment where the stucco will be installed plays a big role in determining the type of lath wire. Coastal areas with high saltwater exposure may require galvanized wire lath to prevent rusting and corrosion. On the other hand, areas that experience heavy rainfall or snow will also benefit from galvanized lath due to its moisture-resistant properties.
Building codes
Wholesalers must check local building codes to determine if there are requirements for wire lath for stucco. This will ensure compliance and prevent issues during the installation process. Additionally, some building codes may specify the type of stucco finish required, which can also affect the choice of wire lath.
Stucco type
There are different types of stucco finishes, including traditional cement-based stucco and acrylic stucco. Each type of stucco may have specific requirements when it comes to wire lath. For instance, cement-based stucco works well with galvanized or stainless steel lath, while acrylic stucco can be applied over polymer-coated lath.
Installation method
The installation method can also influence the choice of wire lath. For example, if using a scratch and brown coat method, a heavier gauge lath such as 3.4 oz. galvanized steel lath may be required. On the other hand, a one-coat stucco system can be used with a lighter gauge lath.
