My home has exterior stucco. I have an enclosed patio room next to my dining room with a sliding glass door in between. I removed the door to open up living space. One side of the opening is finished with stucco and covered with paneling. The other side is regular drywall. I want to trim around the opening but not sure of best way to cut stucco without breaking chunks out. Also, to finish the opening, should I glue corner bead to stucco rather than nail? I want to install drywall to cover framing but not sure of best way to blend in.
