Need help in fixing the grout in the kitchen floor
I need some advice in how to go about fixing my ongoing "dissapearing grout" issue in the kitchen floor.
To make the story short, when the leg column was initially being installed, but porcelain floor (3/8") tile cracked (fault of the installer, not of the tile) and it had to be replaced. Due to the fact that the new one only had 48 hours to dry (it was glued in with thinset), it seems that this time was not enough because when the column was put in, I guess the screws that hold it in place "tilted" the new tile by a fraction. This has in effect makes the tile move (sway) maybe by a couple of milimeters when someone steps on it. We have tried to re-grout the spot 3 times now, but due to this slightest of all movements, the grout eventually cracks and within 5-6 weeks almost dissapears. See the photo attached.
It has been suggested to me that to fix this (without redoing the whole job from scratch, as it is impossible since the countertop breakfast table sits on that leg) that I should try one of the two following solutions:
1) I should mix the grout and right before applying it, I should add a little bit of CEMEX glue and apply that combo directly into the gaps. This way, it will keep the grout color and the cemex will prevent the grout from carcking again.
2) I should just buy a beige-colored CAULK (no idea if acrylic or silicone ?!?), and just fill-in the gaps.
What should I do to make this a more "permanent" solution? I want to whatever I do to be able to withstand cleaning of this "very much used" floor with a WET Swiffer Sweeper cloth, and not having these gaps re-open up.
All suggestions are very much appreciated!
The tile is loose, it needs to be removed and reinstalled. I can't tell from the pic, (too close), but those legs are usually adjustable. You might be able to raise the leg and replace the tile without too much trouble.
Otherwise, you might be able to inject some epoxy glue under there and then use caulk that matches your grout. Might work. :yes::no:
Unfortunately, the leg is not adjustable, and was custom made to my exact specs. So what you are saying is then clean out the existing grout, inject expoxy and then insert caulk? What kind would you use?
I just noticed your post of this over at "do it yourself", with some updated pics. Those tiles are loose, the ones that sound hollow. Even though the grout might still look ok, I guarantee you have hairline cracks. It's not gonna get better.
If you choose to leave these tiles alone and just use caulk as the grout, go ahead and get caulk made by the same people that made the grout. It'll look a little different and is available in both unsanded and sanded. I imagine yours is sanded.
