ctafoya Report post Posted September 7, 2021 Got a question on transition from drywall to cement board. My drywall is about a quarter inch higher then my concrete board. I learned a trick on u tube on how to float to get level, but it didn't mention taping. Would I tape this prior to building up my thin set, or tape after I'm even? I have about the same difference with my pan. Share this post Link to post Share on other sites
bdhuntr Report post Posted September 7, 2021 Put shim strips behind the cement board. A lot work then skim coating it. 2 Share this post Link to post Share on other sites
CatfishKev Report post Posted September 7, 2021 Make sure the drywall edge is screwed tight and not free hanging otherwise if you go over that joint with the tile it will likely crack. You can shim it as mentioned or just float it out with some mud, and don't forget you will have a bed of mud to lay the tile on which will also give you some wiggle room.

ctafoya Report post Posted September 11, 2021 Thanks, I'm going to shim then float. It will be faster and cleaner then trying to pile another 1/4" of thinset on the wall. Share this post Link to post Share on other sites
