9.28.4.1.(2)

Intent 1:

To limit the probability of excessive corrosion, which could lead to inadequate support for stucco or swelling of woven or welded wire mesh, which could lead to delamination, disintegration or cracking under gravity, wind or impact loads, or freeze-thaw stresses.

This is to limit the probability of:

• precipitation or meltwater ingress, which could lead to deterioration, which could lead to the structural failure of exterior walls or elements protected by exterior walls, or
• stucco detaching and falling from the building.

This is to limit the probability of harm to persons.
