Dry time for thinset under hardi and thinset on seams...

Can I install the hardi, tape and mortar the seams, and lay the tile all in one go? Does the thinset under the hardi need to dry before tile goes down? Does the thinset on the seams need to dry before the tile goes down?
thank you

You need to let the stuff under the Hardi cure per instructions...but most people here say they tape and tile all at once. AFAIK at least

By the time you finish taping, the thinset will probably be dry anyway, as it is only a skim type coat anyway. Let the thinset dry as Vic stated before you put weight or tile on it.

Sorry guys...but no. You can install any CBU, tape and tile right away. The only exception is if there's an important game on tv.

I think the OP was wondering about the thinset "under" the cbu. Yeah, as stated the tape can be tiled over almost immediately.

Yes I know, all cbu's require thin set under them.

Spread thin set - fasten boards - mix more thin set for tiles - (a bit thicker) install tiles taping seams as you go. Or if it's a larger job you can tape then set tiles next day, or if you're worried about creating speed-bumps tape the next day too.
