Do I use mapei tape or hardibacker tape.

[provr6]

Ive built my shower enclosure with hardiebacker and am going to tank it with the Mapei kit.

With regards to the boardjoints and the corner and floor junctions should I use the hardiebacker fibatape bedded in adhesive as well as using the mapei tape on top? Im concerned it will finish a bit proud.

The vids I have seen do not show any fibatape but I though this was necessary to minimise cracking.

Any special treatment required to screw holes or just paint with the Mapei?

Thanks in advance

The mapeband strip is textile backed to minimise cracking.
Just really hard to see on the vid.

Regarding the type of tape, a few days ago I had to remove a tile from a shower that had been taped with Wedi tape....it was hard enough getting the adh off the Wedi, but removing the adh off the tanking tape,no chance!...destroyed the tape.

So, I think we are saying that the mapei tape can be used on its own. Do you guys use it on board joints as well or just around the shower tray and internal corners?
