Hi All,

I am at the stage of laying up my drywall and am having some issues with the cement board not laying flat.


Background
  • The wall in question was framed on 24" centers.
  • non load bearing, interior wall
The issue
The board is sitting proud by 1/16" between studs as shown below


In hindsight i should have added some additional studs to bring the wall to conformance.

Should I

  1. Remove the top and bottom boards and re-stud vertically
  2. Remove the top board only and add a horizontal nailing suface
  3. try and blend it together with thinset and tape.
Lastly i am tiling with 12x24" tiles and believe the choice of tile will add complexity.

Hi Bud,

I think I knew the answer prior to posting.

To re-frame the wall will be interesting as i have 2x10 between the studs limiting my access to the sill board. Not to mention the completed pan.

Removing the cement board is not an issue.

Does You/anyone think i will be somewhat succesful studding horizontally to create a nailing edge? and avoid the above mentioned problems.

Lastly how much imperfection can i mask with thinset and tape when i seal the seams?

Hi Bud,

Not sure if i understand "fir it out". Can you explain further.

Secondly, I am guessing i am going to have additional problems.

The cement board is meeting existing drywall that was 1/2". The cement board was .3/8" (much to my dismay as the retailer had it listed as 1/2".)

Anyways i shimmed it out with 1/8" shims to bring it to level with the existing drywall.

I was planning on extending the tiles, past the new cement board and onto the existing board, and figured that i would be able to feather out the difference when mudding.

Hence my earlier question on how much imperfection can i mask with thinset/mortar and tape when i seal the joints?

Seeing your earlier answer i may be removing my cement board and starting over.
