Intent

Intent 1:

To limit the probability of an inadequate bond between stucco and its substrate, which could lead to:

  • excessive shrinkage and cracking, or
  • delamination or cracking 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.
