How Does Self-Furring Lath Installation Work?

Q&A on Self-Furring Lath Installation

1. What is self-furring lath?

Self-furring lath is a construction material used as a base for plaster or stucco applications. It has ridges or furring that create a space between the lath and the wall surface, allowing for better adhesion of the plaster.

2. How does self-furring lath installation work?

The installation of self-furring lath follows several key steps.

Step 1: Prepare the Surface

Before installing self-furring lath, ensure the surface is clean and dry. Remove any loose debris or old material. Examine the wall for moisture and fix any leaks to avoid future problems.

Step 2: Measure and Cut

Measure the area where the lath will be installed. Use a utility knife or tin snips to cut the self-furring lath to size. Always wear safety gear when cutting to protect your eyes and hands.

Step 3: Install the Lath

Starting at the bottom, place the self-furring lath against the wall. Align it properly and use galvanized nails or screws to secure it. Attach the lath every 16 inches along the studs. Ensure the furring ridges face outwards to create space for plaster.

Step 4: Check for Level

As you install, periodically check that the lath is level and even. This is crucial for the final plaster coat to look smooth and professional. Adjust if necessary before securing the entire lath in place.

Step 5: Reinforce Joints and Edges

Where pieces of lath meet, make sure to reinforce the joints to prevent cracks. Overlap adjacent pieces or use additional screws to ensure stability.

Step 6: Plaster Application

Once the lath is fully installed, it's ready for plastering. The ridges help the plaster to grip better, leading to a stronger finish. Apply the plaster in multiple coats, allowing each layer to dry before applying the next.

3. What are the benefits of using self-furring lath?

Self-furring lath offers several advantages. It creates a mechanical bond with plaster, enhancing strength and durability. The space provided by the furring helps to prevent moisture issues, improving the lifespan of the installation. Additionally, it allows for easier leveling and alignment during application.

4. Are there any tips for successful installation?

Some tips include:

• Always use the right tools and materials.
• Work in a well-ventilated area to avoid inhaling dust or fumes.
• Consider wearing gloves and protective eyewear during installation.
• Consult local building codes to ensure compliance.

In conclusion, self-furring lath installation can be a straightforward process when you follow these steps carefully. Proper preparation, careful installation, and attention to detail will lead to a durable and aesthetically pleasing finish.
