Synthetic stucco is an alternative to traditional stucco. This type of stucco exterior hit the U.S. market in the late 1960’s primarily as an option for commercial properties. Over time, the synthetic stucco option spread to residential exterior projects.
The reputation of synthetic stucco suffered from improper installation and poorly trained technicians. Early installations often resulted in moisture damage that led to thousands of dollars in repairs. For this reason, many stucco service companies abandoned synthetic stucco.
However, since then, the International Building Code or the “IBC” has updated the installation requirements resulting in a drainage synthetic stucco system.
Updated code requirements include:
- Apply 2-ply waterproofing paper, Tyvek, window tape, or liquid vapor barrier
- Install all correct flashings, water diverters, and end dams
- Mechanically fasten EPS foam to substrate
- Maintain proper specified grade roof, deck, and slab clearances
- Caulk to seal entire system
