9.28.2.2.(2)

Intent 1:

To limit the probability of inadequate compressive strength or an inadequate resistance to shrinkage or 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.
