Stucco Foundation Weep Screed

Foundation Weep Screed provides a straight and true screed surface at the base of stucco walls, while allowing excess moisture to escape the back of the stucco membrane. It is important for the water-resistant backing paper (Lath Paper) and metal lath to overlap the nailing flange of the weep screed in order to guide the water to the exterior. Check with local building codes for the proper clearance above grade. This bead is required by most building codes in the United States on all framed walls as part of a drainage system for exterior stucco applications (ASTM C1063). Locally, 7/8” thick stucco is the minimum required over wood and lath. Therefore, your Foundation Weep Screed should be 7/8”.
