How to fill a gap between Hardibacker and drywall seam
I'm in the process of a complete bathroom gut and remodel. And in a little over my head..lol! I'm tiling the shower walls above my bathtub. Outside of the hardibacker shower wall, the hardibacker meets up to drywall on a flat surface. Between the Hardibacker sheet and the drywall sheet there is about a 1/4" gap. The tile ends right where the sheet of hardibacker ends. So how do I fill this gap? Do I use spackling to fill it up and then finish each surface as they require (thinset for hardibacker and joint compound for drywall)?
Also, I'm tiling the floor also using hardibacker under the tile. Can the CBU butt up against the tub or do I leave a 1/8" gap and silicone it?
Thanks for all of your help

Reason: another question
when setting your tiles place them over the gap and about 1/4 inch past the sheetrock edge. be careful with the mud and grout so it doesnt go past the edge of the tile. then just caulk the edge neatly.
