| Help - Floor tiles coming off !! | | 2 years ago we had a slate floor laid on to concrete, the concrete had been down about 4 months and the tiler used a flexable adheshive. after about 2 months some tiles started to sound hollow, then they started to crunch when you walked on them and now they are coming up. In some parts of the room they are raised up by about 4mm, when we took some up they lift clean off, the adheshive has stuck to the concreate but not to the tiles. Does anyone know why this has happened? | | |

| Re: Help - Floor tiles coming off !! | | Sounds like the tiler did not clean the slate before fixing | | |

| Re: Help - Floor tiles coming off !! | | Could be that the open time of the adhesive had expired when the tiles were placed on it, in other words skimmed over or the slate was dusty on the back, or that the base was still wet and the contraction as it dried caused the tiles to de-bond ?

| Re: Help - Floor tiles coming off !! | | I'm fairly sure that he didn't clean the tiles before they were laid - would this be enough for them to not stick ?
The concrete seemed dry, it was kicking up a lot of dust - should he have tiled on to new concrete? | | |

It was tiled up to the walls which had been replastered and then the skirting board was put on afterwards | | |

| Re: Help - Floor tiles coming off !! | | New concrete should be left 6 weeks minimum, unless using special adhesive. | | |

The concrete seemed dry, it was kicking up a lot of dust - should he have tiled on to new concrete? | The longer you wait, the better, when it comes to newly cast concrete, but as long as you use materials specced for the age and type of concrete you're using them on, you'll be fine. Vacuum cleaning, or atleast brushing off, dusty surfaces, is definatly something to recommend when tiling. Dusting off tiles before using them is also something I'd strongly recommend.
My guess is that the tiler didn't dust of the tiles properly before using them. It is also very possibly that the tiler didn't use a correctly specced adhesive, in combination with exceeding the open times of the adhesive. |

| Re: Help - Floor tiles coming off !! | | I personally don't think it has anything to do with ,cleaning the slate or the amount of time the concrete was left,i have seen this in the past and it was all down to the thickness of the serrator the tiler used,if he has used a thin notched serrator on the floor they tend not to adhere to the slate instead they stick to the conrete and the tiles are only held in place by the grout until you get some traffic on it .
Not saying thats it but i have seen it a few times with slate and the reason has only been down to the depth of the bed. | | |
