    Tile debonded
    I have a 12"X12" tile installed in our leaving room total area of 10X5 feet, four of them are deboned and raised about 1/8", what needs to be done to restore it back and what will be the case, there is nothing in that area under the tile I mean no plumbing or any thing else, it is approximately 7 years old, Thanks.

    Best Regards,
    John

    Hi John...

    Remove the tiles that are loose... ALL OF THEM. Then scrape the old thinset out so that you can see the floor under it.

    Then take some screws and re-screw the floor to the joists if you can find them.

    Then, plan on purchasing a thinset mortar (dry mix is fastest and strongest) and mix and trowel out on floor using a 1/4" notch trowel. Install tiles so they are level with other floor tiles, let dry 24 hours and then re-grout all. Let that dry 24 hours before any traffic.

    Hope that is what you were asking. Check the tile DRY FIT first and then see if adding that mortar will raise tile out of floor... if so, let me know so we can discuss that.

    Let me know if need more info. Here.

    John, if your subfloor is concrete, then follow Mark's resolution to the tee. If you are on pier and beam, there could be an alternate fix. If the subfloor is wood, follow Mark's instructions all the way up to the thinset stage. Instead of thinset, I have had great success with top grade construction adhesive. Liq.Nls. Or equivalent. Let cure 24 hours and grout. Good Luck

    Hello Mark and shoproland,

    My subfloor is concrete, I am out of country and returning home next week, my wife has removed one piece of the tile and tells me that it has some kind of paper (Fabric) glued to the slab and then mortar and tile, my question is when I lay the tile do I need to install the fabric or just install it with out it, Thanks.

    Regards,
    John

    Tile on top of tile John..? If so and that membrane failed it will probably continue to fail and then entire floor is at risk.

    If not a membrane but more of a backing for the tile then you should just need to install thinset mortar and you should be all set.

    See if you can post a pic. Of the floor/membrane/tile when you get home and we'll see what we can come up with!

    See you! MARK

    I believe you should be able to scrape the area clean and use thinset with an acrylic admix to rebond. Allow a day to cure and regrout. When you go to regrout, make sure to saw out some of the existing grout to give an extra toe hold for the new tile and grout. Good luck... Roland

    I haven't seen it yet, I think it is not a membrane, it sounds like a backing for the tile, I will let you know when I come back home next week, Thank.

    Does anyone know what that paper or membrane could be? I've never seen tile with a membrane other than a backer board or subfloor. I'm very curious now and want to know what it is. If you could post a picture that would be great.

    Hi Amsteube...

    John has sid he is pretty sure that it is not a membrane in this case.

    There is a fracture membrane they sell that allows for some pretty serious movement from the floor below before tiles will come loose...

    I will try to get a name on this product and post back over the next couple of days...

    Daltile makes dal-cim 500 crack isolation membrane this could be the product
    If this is the case you may still have some movement
    I would just replace the area as needed, and see how it holds up:)
