Why does nobody talk about the right way to handle inside corners on a high ceiling?
I keep seeing guys try to tape a 12 foot inside corner with a single piece of paper tape, and it always sags or wrinkles before it sets. On a big job in Denver last fall, I started cutting my tape into 4 foot sections and overlapping them by an inch. It takes a bit longer, but the finish is flat every time. Is this just a local thing, or do you all have a better method for those tall corners?

Watched a buddy struggle with that exact problem on a church renovation. He switched to your method of shorter pieces and it solved the sagging for good. Sometimes the slower way is the right way.

Yeah, cutting the tape is the only way to go on anything over 8 feet. The glue just can't hold that much weight wet. I'll even go down to 3-foot pieces if the mud is a little thin that day. The key is a solid inch overlap and feathering that joint smooth when you bed it. Trying to fight a single long piece is a waste of time, you'll always be fixing a bubble or a wrinkle later.
