    Failed anhydrite floor

    I went to look at a floor that had failed a couple of days ago and of the 60 m2, not much of it seems to be left attached to the screed. The grout is cracking and most tiles sound hollow.

    Gyvlon/Anhydrite

    There's lots of info here on preparing these screeds for tiling. Sooner or later though, we'll come across one in a re-tile situation. Will it be obvious that its an anhydrite screed and will there be any extra prep other than hoovering and priming?
