When we do our exterior stucco we meet or exceed all requirements from the townships code department. Although there are many good stucco companies out there please be aware that there are many who cut corners by not putting the appropriate amount of cement, by using cheaper metal lath or by stapling the metal instead of nailing to save time. They are the reason so many people with newer houses that have stucco are having problems as early as the first 3 years. We install 2 layers of “D” paper (vapor barrier). Next we install 2.5 gauge galvanized sulferring metal lath, then apply 2 to 3 coats of cement base coat to approximately 7/8” thick.
