3/4 rib lath must weigh how many pounds per square foot in the listed options?

• A. 0.60
• B. 0.65
• C. 0.70
• D. 0.75

Answer: (A)

Weight per square foot is a fixed spec for each lath type and is used in plastering calculations. For 3/4-inch rib lath, the standard weight is about 0.60 pounds per square foot. This figure comes from common metal lath data sheets and practice tables, where the rib height and spacing define how much metal covers a square foot. Because this type of lath is lighter than thicker or denser options, its psf value sits at 0.60. The other numbers correspond to heavier lath or different configurations and don’t apply to the standard 3/4-inch rib lath.
