Sentence 9.28.6.5.(1)

Intent 1:

To limit the probability that the base coat will extract and absorb water from a relatively thin finish coat of stucco, which could lead to negative effects on curing of the finish coat, which could lead to an inadequate resistance to abrasion or freeze-thaw stresses, which could lead to delamination.

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.
