For the seemingly fewer and fewer of you that are still using cement boards for shower walls, does your seam taping process look like:

1. Thinset between joints

2. Lay alkali cement board tape over wet thinset

3. Thinset over tape

Or

1. Tape dry seams

2. Thinset over tape

The only place I’ve ever seen recommending the first method is durock instructions which obviously carry some weight, but I have watched many videos and nobody is prefilling joints.

Thanks in advance.
