9.28.3.1.(1)

Intent 1:

To limit the probability of the premature failure of fasteners, which could lead to an inadequate bond between stucco and its substrate, which could lead to delamination 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.
