Framing & StructuralQuestion 385 of 700
When applying three-coat Portland cement plaster (stucco) over wood framing on an exterior wall, a weep screed must be installed at the foundation plate line at least how far above the earth?
a.1 inch above earth
b.2 inches above earth
c.3 inches above earth
d.4 inches above earth (or 2 inches above paved surfaces)
Explanation
A corrosion-resistant weep screed must be placed a minimum of 4 inches above earth or 2 inches above paved areas to let moisture drain out of the wall assembly. 1, 2, and 3 inches above earth are insufficient clearance and could wick soil moisture into the plaster and framing.
