Shower Waterproofing

sheet membrane & wall seems (what order)?

I'm finally getting back to sealing shower after the permabase cement board is up.

I'm ready to put down my sheet membrane with multimax light and tape the wall joints and corners.

I have premade inside and outside sheet membrane corners and mesh tape for wall seems.

1) What is the correct order of install on all of this?

Floor membrane 1st?


2) can I use Mapei Keraflex Plus for the taped wall vertical joints?
