9.28.6.1.(1)

Intent 1:

To limit the probability of inadequate strength of the base coat to provide support for subsequent coats [as required by Sentence 9.28.6.2.(1)], which could lead to an inability to resist gravity, lateral, impact or abrasion loads, or freeze-thaw stresses, which could lead to the cracking of stucco.

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.
