I replaced the walls in my bathroom and used concrete board around the shower. I plan on finishing the concrete board joints with the proper mesh tape and (premixed) thin-set as recommended but ...

I don't know how long I should let the joints dry before gluing up the tub surround.

    Isn't it written on the side of the bucket of thin-set? – user25447 Dec 3 '14 at 21:51

    And if you add joints there with mesh tape and thin-set, won't it protrude too much that your wall will no longer be flat enough? – user25447 Dec 3 '14 at 21:59
  • @AlexandreVaillancourt Feathering, right? – iambriansreed Dec 4 '14 at 15:39
  • I'm sorry, English is not my main language, and I'm not familiar with the term "Feathering". – user25447 Dec 5 '14 at 18:28

in my experience, let it dry first - just as you would let joint comound dry...dry to the touch and firm. I've pushed the envelope on a couple of occassions and what enbds up happening is the thinset shrinks as it dries, sucking the tile in, and causing a hairline crack.
