If anyone has any tips for making the joint between the new wall drywall sheets and the existing ceiling drywall look good, please share them with me. I'm somewhat familiar with drywall taping since I put it in a large workshop I built a few years ago, but it was all NEW drywall.
Would it be beneficial to make an incision about 1/16" deep about 2" from the joint all along the ceiling sheets, and scrape out the old paper tape and joint compound from those sheets? This would provide a shallow channel to bed the new tape and it seems it would be easier to smooth out the compound.
I've always used the conventional paper tape; would the fiberglass mesh joint tape be better for this project?
