Making straight drywall lines next to firebox
I installed a directvent fireplace that will be surrouned with drywall. I have cut the drywall to be straight and les than a 1/8" gap from the firebox sides. However there is still a bit rough lines do to the drywall paper. I would like the lines to look as best as possible.
I want to have a smooth finish when its done so is it possible to run a peice of tape along the edge of this drywall to create this straight edge and just mud and feather out the sides? If so what type of tape shoud I use fiberglass and paper?
