    Jst another add-on, like to know what adhesive was used. Looks like a normal cement based product, probably modified with an additive of some sort.

    Just to get this straight, there is piped water heating beneath the ply? Are the pipes set into something? 22mm ply? How's the heating going to be effective? it still has to go through the tile.
    He Probably thought he was doing a thorough job putting down 22mm ply.
    Priming is the least of his concern, looks like he's used a 6mm spreader and no coverage.
    Your right Alec,looks like a standard tilefix.
    Oh, and how is the ply fixed down?
    Not sure who does the UHF over there, but would a tiler put piped UHF down himself.
    Just for any guest viewers info, how should this have been installed properly? Correct layers etc.

    Looks like two types of adh have been used like the way the ply join has gone straight through the adh

    And tiling while the heating is on. :confused: that adhesive has thermal shock written all over it.

    Typical behaviour of the ply. It will move and if you don't isolate that movement this is the result.

    The piped heating sits between the joist in insulated metal trays and the ply in ment to be fixed to the joist as the finished sub floor. This was all installed by the builder and is a common method. The heat passes through the ply to the tiles no problem.

    The failure came about in IMO, because the ply was insufficiently fixed to the joists (6 screws per sheet) wrong primer for the addy, not turning the heating off for the installation, tiling directly to the ply (though still a recommended form of installation) wrong trowel size for the standard addy that was used!

    6 screws per sheet!!!!! What was he thinking, oh, I know, the weight of the tiles would hold it all down. Ha Ha.

    And people think they are safe putting an acrylic shower in, lol. The number of leaks I have seen from these things, even just installed
