The Western One-Pass® System is a code-recognized exterior stucco wall assembly utilizing Western One-Pass cement plaster in conjunction with approved weather-resistive barriers, metal lath, and compatible finish systems.​ Recognized under IAPMO UES ER-382, the system is uniquely formulated to function across multiple stucco assembly types, including one-coat, conventional scratch-and-brown, and monolithic cement plaster applications up to 7/8-inch thickness where permitted.​ Unlike traditional plaster systems limited to a single application method, the Western One-Pass System provides a universal exterior plaster solution adaptable to commercial, custom residential, and residential construction. The system may incorporate the optional Crack Resistant System (CRS) and may be configured with fire-resistance-rated and NFPA 285-compliant wall assemblies in accordance with ER-382.
