Intent

Intent 1:

To limit the probability of:

  • drying before hydration is complete (or inadequate curing), or
  • the cracking of stucco due to shrinkage, or gravity or lateral loads.

This is to limit the probability of:

  • excessive moisture transfer by capillary action, or
  • inadequate strength to resist gravity, lateral, impact or abrasion 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.
