This course will help building design professionals to:

• Understand the history of Portland Cement-Based Exterior Plaster (Stucco) and why this cladding is the best fit for warm, humid, hurricane-prone climates.
• Review the ASTM standards step by step to understand positives and negatives, and minimize/​eliminate potential problems.
• Realize the specific challenges of Climate Zones 1 and 2 and why Portland Cement-Based Exterior Plaster (Stucco) needs to be considered differently in southern and coastal climates versus other climate zones.
• Compare face barrier systems versus other water management design options.
• Test their ASTM standards knowledge and learn what to look for in correct construction techniques that provide occupant safety and limit liabilities.
• Build a warranted exterior envelope system with proper finishing standards and trained, certified installers.
• Identify potential long-term pitfalls to provide a schedule for proper maintenance and repair.

Upon completion of this course, building design professionals will be able to:

1. Describe the reasons and rationale for specifying Portland Cement-Based Exterior Plaster (Stucco) for warm, humid, and hurricane prone climates.
2. Understand specific ASTM standards, what they do (and do not) include and how to apply them.
3. Build a correct specification that includes proper ASTM tests and correct details for your specific climate zone.
4. Identify the specific installation problems and apply time-tested solutions to maximize occupant safety and minimize potential liabilities.
5. Know what steps are needed to provide the owner with a warranted exterior envelope.
6. Articulate the need for trained and certified installers and document a long-term maintenance schedule.
