slight misshap

This comes to you a little to late, but for my own sanity I was wondering how bad I screwed up. I just finished laying tile in my folks kitchen, all done according to what I read on this site, except one thing, after I finished laying the tile I realized I hadn't taped any of the seams on my hardi board. Is this going to be a serious problem someday, or do I just have to sit back and wait and see? Your thoughts would be much appreciated.
Thanks, Peter

What choice do you have other than wait and see?

It's a critical step and I'm sure the thinset that you packed in the joint (?) is already cracked. No telling if the movement will eventually show in the tile work with cracked grout or cracked tiles. It may not ever happen.

I can show you right here today in my town a job that was originally installed earlier this year for about $38K that is (as we speak) being torn out and reinstalled to the tune of more than $70K. For those guys, not taping the seams was a huge ommission on their part.

Sit back and see what happens.

Darn, I was afraid of that. I guess that's what I get for rushing it. Out of curiosity, Bud was that job in your town installed the way you guys do it, and they just forgot to tape, or did they try and slide by with other shortcuts, like adding no plywood, or the joist span was to big, something along those lines?

Pete, look at the bright side. It could have been your in-laws house

Pete when things begin to come unravelled you can imagine all you hear are excuses and installers saying: "In all my years I never before had a problem doing it this way". BALONEY!

I don't know of any installer that goes around bragging about his failures.

I can tell you there was a comedy of errors performed under the flag of professionals in this case, now all those guys involved are backpeddling really fast.

The installers claimed in the past they used to tape the seams but now they don't. But I'll bet now they do again after this.

Hey, another question for the pros, at this point I'm stuck with what I got, and I'll just hope for the best, however, I have yet to grout the floor, and I'm wondering if there are any "hail mary's" out there that might help my screw up. Obviously nothing can change what I did, but is there any tricks that might help the situation? I remember reading about additives for grout that can increase elasticity in the grout. I guess what should my next move be? Thanks!

So all the untaped seams are under grout lines?

No, for the most part the seams are all under the tile, I just figured the first place to crack would be the grout. And since that's the only thing left I can influence, I figured I better ask before I do anything!

No, for the most part the seams are all under the tile,

EXACTLY! The type of grout used WILL NOT influence where the tile will break.

Use any grout you like and let this run its course. You have no options at this point.
