What are your drywall/cement board/framing flatness tolerances for tile supporting walls?
I am rebuilding half of a frame and it is a challenge to bring all the studs in the same plane. I do know about the tricks used to straighten studs but I am thinking there must be some tolerances in this respect
Update:
this is related to this thread.
Can I use corner brackets to rebuild a wall frame that has the horizontal 2x4s extended in an adjacent room?
I build my second half of the frame and now I am trying to align it with the existing and it seems to be complex since the top and the bottom plate could be aligned using a long level as straight edge but then studs might not be in the same plan with the other half that is already there.
I am using a vertical laser and double checking with the 8' straight edge-level
Update2:
this guy is doing it using thinset. Is this normal? (you can call this floating the cement board I guess)

Update3: this guy is floating the tiles instead

Just use drywall cardboard shims or sistered studs to bring the studs into plane. TCNA says 1/4" deviation over 10'. If using large format tile, trying to level with thinset after will take way longer and be more frustrating than the time it would take to make sure the walls are straight and plumb
