Seams not taped under travertine floor
DougLanglois

I'm a DIYer dealing with a stone floor where the backer board seams were not taped. I'm also pretty sure the floor doesn't meet the required deflection standards. Predictably, the tile has cracked along every seam in the backer board.

Is there anything that can be done to save this floor? I've read that you can fix cracked tiles with epoxy or color matched caulk (!?), but since this is a symptom of an underlying problem, won't these fixes just fail too?

If I install blocking on the floor to reduce the movement, can I pull up the tile along the seams, sc**** the thinset back, tape the seams and re-lay?

Preemptive defense: I wasn't the one who did the job!

1. Repairing a broken tile will never look like a new tile. The proper way is to replace the tile.

2. Replacing a broken tile without taping the seam under the tile, will set you back to square one, and a new crack will subsequently appear.

3. That brings me to the deflection issue: your floor must be able to carry the load, that's rule #1.

Go on to johnbridgetileforum - look for their deflection formula to see where you're standing.

Thanks.

Assuming the floor meets the L/720 deflection requirement (which remains to be seen), is it going to be possible to remove the thinset well enough to do a good taping job?

Yes you can "patch it" with caulks or grout but it won't last and if the substrate wasn't taped then it wasn't installed correctly so the seams may not be the only problem with it. Best to do it right by redoing it, and if you can't afford that patch it for now and start saving for the re-do you need. And head over to the John Bridge site to learn what you'll need so that you can ensure that the next tile contractor does the job right!

The easiest way I have found to fix a bad tile job is to tear it out and redo it properly. I have seen just as many half ass tile jobs from contractors as I have from ameratures.
