Type F3/8R metal plaster base must weigh how many pounds per square yard in the listed options?

• A. 3.4
• B. 2.0
• C. 5.0
• D. 6.0

Answer: (A)

In plastering, the weight per square yard of the metal plaster base is a defined spec that affects how well the plaster will be supported and performed. For the Type F3/8R metal plaster base, the standard area density is 3.4 pounds per square yard. This weight provides enough rigidity and support for the plaster coat without adding unnecessary dead load to the wall. Lath that is too light won’t adequately support the plaster, while heavier options aren’t required for this base type and would just add extra weight. The other values don’t match the established specification for this lath, which is why 3.4 pounds per square yard is the correct choice.
