I am remodeling a bathtub shower surround.
I tore out the old tile and drywall and installed hardie backer.
It goes all the way the ceiling.
The drywall on the ceiling is in good shape and I don't want to have to refinish it. How should I fill the gap between the hardie backer and the drywall? I could use modified thin set, caulking etc. I don't want to put mesh tape over the joint as it will show on the ceiling.
