Combine WrapShield SA Self-Adhered WRB/Air Barrier and VaproMat, a lightweight polypropylene drainage matrix to reduce the incidence of moisture related damage behind cementitious materials.

  • Create a first-class air barrier with WrapShield SA Self-Adhered, then overlay VaproMat creating the much needed drainage plane behind stucco.
  • Ideal for use with stucco or cultured stone, VaproMat is designed to keep the drainage cavity unobstructed during the lath and plaster installation.
  • Constructing a rain screen cavity behind cementitious cladding permits moisture to drain freely down the cavity, away from the structure, allowing the stucco to dry from both sides.
  • Easily works with traditional cladding systems, no change to design or installation practices are required.
