[F20,F61,F80-OS1.1]Applies where stucco is applied to masonry chimneys.

Intent

Intent 1:

To limit the probability of:

  • inadequate density to resist water absorption,
  • inadequate strength to resist gravity, lateral, impact or abrasion loads, or
  • inadequate resistance to freeze-thaw stresses.

This is to limit the probability of the cracking of stucco.

Where stucco is applied to masonry chimneys, this is to limit the probability of precipitation or meltwater ingress, which could lead to the premature failure of chimney liners, which could lead to the escape of heat or flames, which could lead to the ignition of combustible building components, which could lead to harm to persons.
