Which type of lath must plaster be dried in a more controlled manner?

• A. Metal lath
• B. Wood lath
• C. Plastic lath
• D. Composite lath

Answer: (B)

Plaster applied over wood lath requires a more controlled drying process because wood is more susceptible to moisture changes compared to other materials. Wood lath can absorb moisture, which can lead to problems like warping, mold growth, and degradation if the drying is not managed properly. In contrast, metal lath, plastic lath, and composite lath have different properties that allow for a more rapid or less critical drying process. Metal lath is non-absorbent and provides a stable surface that facilitates quicker drying, while plastic lath and composite materials also tend to have moisture-resistant qualities. Consequently, wood lath’s ability to retain moisture necessitates a more gradual and monitored drying approach to prevent damage and ensure the integrity of the plaster. This understanding is essential for any professional in the field, as the drying method influences structural stability and longevity.
