Hello all, I am new here (and new to hanging and finishing drywall) and can't seem to find an answer to my question anywhere on the internet. I have a basement bathroom that I am finishing that is approximately 7.5' wide by 11' long. I purchased two 4' x 12' sheets of drywall for the ceiling and had to strip one down. I left the tapered edges in the middle of the ceiling which leaves one side with a butt edge. I then hung the drywall horizontally with top row first (so tapered edge meets ceiling). So my question is, when I have a tapered edge of my wall meet the butt edge of the ceiling, do I finish it as normal or do I prefill the taper? Or something all together different? Any help would be appreciated, thanks!
