Answer

Thank you for using Just Answer!

You should use both a layer of Tyvek and the paper back lath. If you do not use the paper then the Tyvek can actually bond to the stucco, causing water to pass through the Tyvek and wet the building materials. The paper (Grade D) provides a "break" between the Tyvek and the stucco.

Accepted Answer

The Florida Building Code requires 2 layers of weather resistance barrier behind stucco. The Tyvek and the paper back will comply as 2 layers.
