Lathing is the first step of a new stucco project. Lathing not only protects against moisture intrusion to the framing of the house, it also ensures a sturdy support system for new stucco or hardscape work. The lathing process itself includes several steps. These steps include: installing weep screeds, asphalt coated waterproofing paper, lath (pronounced like “bath”) wire, expansion joints, milcore, plaster stops, corner aids and arch aids as needed. Below you will find a quick overview of each step and product used.
Weep screed is a lath accessory that aids in expelling moisture at the bottom of a wall as well as prevent water from wicking up the wall. The weep screed is installed at the foundation line along the house, a minimum of 2” above paved or 4” above graded surface. Weep screed comes in a variety of metals, including copper, galvanized steel, stainless steel, aluminum and zinc.
Asphalt-Coated Waterproofing Paper
Also known as 60-minute paper, this is a needed barrier between the framing of the house and any outside moisture. The 60-minute paper is highly resistant to water. It is installed against the exterior framing of the house in a layered fashion, from the bottom of a wall to the top, creating a trickle down for water or moisture.
