Intent

Intent 1:

To limit the probability of an inadequate physical bond between the finish coat of stucco and its substrate, which could lead to an inadequate resistance to 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.
