You're not going to sand a 1/16" off of drywall without removing the
paper. It's a stupid idea.

Hence the mastic and the mesh tape to provide the needed strength on
the joint... and covering that with tile... to hell with the paper.

IMHO It's a ****ty idea. He'll see. He deserves the mess it will be
anyway. He had to have seen the potential problem before he started and
chose to ignore it.

Simple way is to do as I said. Which he could have planned for. Cut a
bullnose tile to fit up to the transition and forget about lapping it.

The OP's a moron.
