Weep screeds shall be a minimum of ______ corrosion resistant weep screed or plastic weep screed.

• A. 0.10 inch
• B. 0.25 inch
• C. 0.019 inch
• D. 0.26 inch

Answer: (C)

Weep screeds need to be corrosion-resistant and thin enough to function properly as a return for moisture while staying compatible with stucco install details. The minimum thickness specified for corrosion-resistant weep screed or plastic weep screed is 0.019 inch. This gauge provides sufficient durability against the wet, exposed environment without adding unnecessary bulk that could interfere with flashing, alignment, or drainage. The thicker options would be heavier, less practical for this flashing component, and not required by the standard.
