I am in the middle of laying this floor the past two days, by a local carpet dealer.The grout was applied yesterday, they said wait two days /48 hpurs,before heavy traffic, PROBLEM IS; the grout is shrinking! and cracking everywhere !! What is the thing to do now,Do i demand removing all the grout /is this the thing to do? /apply more grout ?/wet over dry???????The more it shrinks the more cracks i'm getting. This is very reputable dealer. I don't want to act unjustly on this.
But what am i in for down the road, with mixing grout [wet] with already dry. grout? help please!! they will be packing up to leave today.
ps i can see the floor beneath the cracks! bob s

Assuming this is probably Duraceramic or something like it here's what's likely happening.

They are using too much water to clean the grout and they are allowing cleaning water to get into the grout joints where they have not installed the grout yet. They are installing grout over water puddling on the substrate between the tiles. This excess water will also erode the adhesive and cause the tile edges to curl over time.:yes:

I'm sure the dealer is reputable but his installers are just being sloppy and probably trying to expedite the job. If you haven't paid them in full, DON'T, until you are sure you are satisfied with their work.

Applying fresh grout over those cracks is probably do-able, but if water has wicked under the tile edges the problem won't show up right away. It may dissipate harmlessly but it also may not.:)

Armstrong's Response to Grout Issue

Hi!
When installing Armstrong vinyl tile that is able to be grouted, cracking in the grout can occur for multiple reasons. First, confirm that the type of grout you are using is a premixed sanded acrylic grout. No other type of grout will work on these tiles. The next likely culprit is using too much water during the initial grout clean-up. In some instances when attempting to install or clean the grout off the surface of the tile, an excessive amount of water makes its way into the grout. When this happens, the grout takes on too much water and once it dries, shrinks down and loses volume. This is similar to how mud cracks after it dries.

Other potential causes to this issue include having joint widths that are too wide or too narrow, failure to pack the joint fully during installation or subfloor movement. The solution is to replace the grout in the impacted areas. One advantage of using the correct type of grout is that it can easily be reapplied on top of itself anytime after the initial installation has been completed.


Hope this helps!
