I am in the middle of a bathroom remodel and have to tape the joints of the
drywall and hardibacker. My question is what to use when the hardibacker
meets the drywall, tape and spackle or mesh and thinset? Also, do you use
the metal 90's to brace the corner edges like you would w/drywall, or do you
just tape and set them at about a 90 degree angle. Thanks in advance.
