Creating a tape groove for a drywall patch
Due to water damage, I had to remove the bottom four feet of a wall. Now I want to put up new drywall in the bottom section. The new drywall will have the indentation for the tap and mud where the new and old drywall meet. What is the best way to do the taping. Do people pound the old drywall near the edge to create an indentation for the tape? Or do they just add the tape to the existing drywall and feather out the edge. Also, is putting the tape groove at the top the right way to go or is it better to put the cut edge at the top so there is no indentation and two pieces of drywall match?
