In a bedroom, I need to build a new interior partition 90 degrees off an existing wall. The existing wall is painted (Benj. Moore eggshell latex) and the new construction will need to be taped at the corner where they join together. Can I just tape this corner like it was all unfinished drywall, or will I need to prep the existing painted surface to affect a good bond and sound tape joint?
