I just had a new electrical meter and panel installed that is about twice the size of the old one. During the process, we knocked out a large section of stucco to make room for the new panel.

The instructions on the panel say that the tar paper should over lap the flange of the new panel. We were carful to not remove too much stucco, and now I am wondering if these steps would work.

1. Cut thin strips of tar paper (rated for this purpose) and insert under the old paper and over the flanges.

2. Bend back the bent chickwire remaining until it is flat. Tie new wire to the old where needed.

3. Apply one coat of stucco patch repair into the trough between the semi flush panel and the remaining stucco edge (about 3/4" or so).

4. Once main coat is dry a few days, follow up with stucco patch repair for texture.

 

Sounds like a plan. If the stucco is painted you might wire brush the paint off around the edges for better adhesion to the old.
