I used to think taping a corner was just about getting mud in there
For years, I'd slap on a thick coat, fold my tape, and hope for the best. The results were okay, but I'd always have to do a ton of sanding to fix little bubbles or ridges. Then, about six months ago, I was helping a friend redo his garage in Springfield and saw him use this old metal corner trowel I'd never bothered with. He pressed the tape in with it, really working it from the center out, and used almost no mud. I tried it on the next corner, and it was like night and day. The tape laid flat with no air, and the finish coat went on so smooth. I mean, it added maybe two minutes per corner, but it saved me at least fifteen minutes of sanding later. Now that little trowel is the first thing I grab. Anyone have a different corner trick that saves them time?
