9.28.2.3.(1)

Intent 1:

To limit the probability of the accelerated deterioration of stucco or corrosion of fasteners, metal lath or reinforcing, which could lead to inadequate strength or resistance to freeze-thaw stresses, which could lead to the delamination or cracking of stucco 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.
