Hi to all,
Just to expand on the above, poor stucco application is a huge problem. What many inspectors/installers are failing to realise is that all of the components of stucco other than the finish are porous to a certain extent, even the CMU's are themselves porous any defficiencies in the application of stucco will lead to moisture entering through the finish.
This is abviously an even bigger issue with timber clad structures where any moisture migrating through the stucco finish will lead to rotting of both the substraight and the framing.
Also as someone else suggested go watch stucco being applied, many of the shrinkage issues associated with stucco are caused by too many coats being applied too quickly, each caot should be allowed to dry out properly before the next is applied, this seldom happens (it is not unusual to see finish coat being painted whilst the stucco crew is still working on other areas of the home).
