I have a legacy window that I am boarding up, for reasons of interior layout.
As the surrounding wall is stucco finish, I want to do the same over the boarded up window. I was thinking to just screw some lathe over the OSB and then stucco over.
However, I am concerned about waterproofing.
Should I apply some material over the OSB to waterproof it, like maybe roofing felt paper or vapor barrier (the latter may impede adhesion of stucco)?
