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

• A. .25 inch
• B. .26 inch
• C. .10 inch
• D. .019 inch

Answer: (D)

Weep screed is the bottom element of a stucco system that must stay durable in a wet, corrosive exterior environment. The minimum thickness specified for corrosion-resistant weep screed or plastic weep screed is 0.019 inch (about 0.48 mm). This thin gauge provides enough strength to resist corrosion over the life of the cladding while keeping the screed light, easy to install, and compatible with typical mortar and drainage clearances. Thicker options would add unnecessary weight and cost and could interfere with proper drainage and installation. The chosen thickness balances durability with practicality, which is why 0.019 inch is the correct minimum.
