Which method is NOT acceptable for fastening metal lath strips?

• A. Welding
• B. Screwing
• C. Powder-actuated fasteners
• D. Glue

Answer: (D)

Fastening methods for metal lath strips must ensure a secure and durable attachment to support the weight of the stucco or plaster that will be applied on top. Options such as welding, screwing, and powder-actuated fasteners are all widely recognized techniques in the construction industry for affixing metal lath strips because they provide the necessary structural integrity and longevity. Welding is a robust method that melts and fuses metal parts, ensuring a lasting bond. Screwing offers ease of installation and allows for adjustments, while powder-actuated fasteners provide speed and efficiency for attaching metal lath to concrete or masonry surfaces. On the other hand, glue is not an acceptable fastening method for metal lath strips. While adhesives can bond materials together, they typically do not provide the strength required to hold lath in place effectively under the weight of plaster or stucco. Additionally, the adherence may degrade over time due to environmental factors such as moisture, leading to a potential failure in the installation. Thus, using glue would compromise the stability and integrity of the lath application, making it an unsuitable choice.
