I’m not a builder but I have noticed in the past that before stucco is applied they use something like a tarpaper backing against a structure, then they tack or brace like chicken wire over it which is attached to edge boarding. Then they apply and adhere the plaster/stucco to the surface of the chicken wire that holds it in place.
