Question DetailsAsked on 8/6/2017

The grout between our brand new honeycomb mosaic marble tile on our shower floor is already cracking. Best repair?

We hired professionals to install a tile shower. They used the Schluter system. We have been using the shower for two weeks. The grout between the honeycomb mosaic marble tile on the shower floor is already cracking. Professional wants to regrout over the existing with a polymer additive and not remove existing grout. Also found out the professionals sold us wall tile and not floor tile for the shower floor (specifically not approved for shower floors). Not sure where to go from here and how best to repair the floor. HELP!

Assuming here the installers provided the tile too - not that you bought it somewhere else, in which case your share of the responsibility would be much higher.

Argghhh - Schluter system. If they used their grid flexible pad system under the shower floor, my sympathies and no solution other than tearout, in my opinion. There should NOT be any flexiblilty in the flooring - an invitation to cracking.

Regrout over cracked grout with polymer sealant - what a joke. That does nothing about the cause of the cracking - which might possibly be (if cracked in first day or two) incorrect curing, but most likely is due to movement due to inadequate rigid support under it - due to installation system, or possibly due to inadequate subflooring (which should be 3/4" and preferably marine or treated plywood under a shower - not particle board or OSB, in my opinion, even though the code usually allows that.

Wall tile rather than floor - that alone gives you cause, if it was specifically labelled as not approved for shower floors, to demand they remove and replace with proper floor-rated tile. Not knowing what the ratings are, could be the backing was not rated for floor use, the traction of the tile is not up to standard for the friction level needed in a shower floor, or who knows what - but if it says not for use on shower floors then you have ample cause to demand they remove and replace (and also fixing the cause of the cracking at same time) at no extra cost to you.

Also, for a mosaic floor, I can't see economiclaly removing the grout and replacing it even if that were a viable technical solution (which I do not see it being as such) - just too many short joints with angled intersections - tearout is the only solution I see, which to avoid problems with the underlying layers should usually go all the way to the subflooring for a total redo of at least the shower base and floor.

If they refuse, assuming this is a recent installation, then I would call their Bond - contact the bonding company to have them pay to have it redone right, at no extra cost to you (they ultimately recover the cost from the contractor).

And of course, once all is said and done, sounds like an appropriate and honest Review on Angies List and maybe Yelp and such would be in order.
