I've removed the old cement boards and I've put new ones up on the shower walls. My tile will not go to the ceiling. I'm at the step where I need to apply thin-set and tape to all of the cement board seems. What do I do at the seem that transitions from cement board to sheet rock?
yes, and make sure that walls are Straight and LEVEL, or you will not be happy with results.
Use Hardibacker and seal the seams with tape and thinset. Use thinset to set the tile using 1/4 spacers. I have used and recommend that you use a tile sealer to seal the slate prior to grouting and to use epoxy grout. The grout is more difficult to install but requires no sealers which need to be redone at least once a year in a shower and is well worth the initial time and effort. Be sure to read and follow the directions on the grout bags to ensure a uniform color and good grout set. MT C
Yes tape those seams too. Make sure you nail the dry wall there too w/ a galvanized roofing nail. You may have to do so floating w/ thin set to get it flush but it ll work fine. The thin set , when gluing to dry wall needs to be a fresh batch or just a BIT looser and wetter since dry wall will absorb the thin set fast. Not wet wet just a bit looser. Any questions you can e mail me thru my avatar and check my qualifications there GL
