Is thinset OK at Dywall/Cement Board Transition

Hi folks

I have the durock and drywall up on a new bathroom. The 12 x12 tile will come up about 2 inches about the cement board at its highest point.

As far as the transition, what is my play on the tapered horizontal cement board joint and the tapered drywall joint.

My thinking is to just use fiberglass and thinset for the whole joint, but I'm wondering about thinset's adhesion to the drywall. It seems silly mud half of it (the drywall prortion) only to see if covered with thinset again when the tile goes up.


Any help would appreciated.

A tile setter might have a different idea but I like yours.

If a tile setter told me differently I would listen to him. But I think what he would tell me is to treat that Drywall/Durock joint just like the joints in the Durock. Don't carry the thinset too high on the drywall. You don't want to have it end above the finished tile line.
