My design drawing has a simple trim around window but my contractor did not ask me and applied stucco around the window. Now I can only add the trim on top of stucco. I want to make sure the trim is weather resistant and its application should not subject the stucco wall to leakage.
I would like to know what is the best material for window trim on stucco? Is HardiTrim (HZ10, 1" x 3.5") too heavy to be placed on stucco?
