Drywall & Hardiebacker meet on a stud...love at first sight? (to tape or not to tape)
Questions regarding hardiebacker meets the drywall.
I am a tall fella so the tile is about a foot higher than usual.
Thus putting the intersection even farther from the spray of the water.
The tiles sit atop 90-95% of the HB.
They overlap the drywall about 5-10% of the drywall. (maybe 1 cm)
----If the tile overlaps slightly...and its well caulked.....is it totally necessary to use that fiberglass mesh tape?
Structurally I can see little to no benefit as a settling wall isnt going to be deterred by fiberglass mesh tape.
Moisture wise the tile and caulk will repel the water.
Ergo, I get the rationale for mesh tape adjoining the actual sheets of HB under the tile ....but a this HB and DW intersection (higher than normal) I see no real structural or moisture rationale. Am I missing some great equation of life, love and shower installation?
