Pending disaster?

Iv'e had this especially with cheap turkish tiles, I think if you are using tubbed then it's not wet enough and I myself have wet these tiles prior to fixing as they are very porous, I now tend to use cement based powdered stuff, less chance of failure.

Okies I shall leave them for a bit.

Just been back for another inspection.... The adhesive left on the wall from the tiles I took of last night is a lot "whiter" than the one I popped off this morning. So I assume that has dried out over night where now there is no tile covering it.

Keraflex Maxi is cement based isn't it?

Not sure of the quality of the tile they are Azteca Ceramica Elements jobbies. They didnt seem that cheap but what do I know! 🙁

Is the Kerraflex maxi tubbed or powdered? I prefer powdered now as you can mix it a bit wetter if needed.

Keraflex maxi was powdered and mixed reasonably wet. As I say if you ploked a tile into it then pulled it out you would get good adhesion to the tile and "peaking" in the adhesive on the back of the tile when you pulled it away.

Sounds like you did it to a decent spec so I'd imagine it would be fine. If you're unsure, pull off the tiles while the come off and give them a wipe, score the adhesive on the wall and 'back-buter' the tile and press them back in again? Maybe?

*Shouts* Daaaaaavvvveeee?

i use kerraflex and kerraquick all the time and have never had a problem, i would imagine it's dust on the back of the tiles and not failure of the adhesive unless it was mixed too dry..Mark.

I'm not familier with the Mapei stuff you have used but if it was bucket stuff it will take time to dry properly. If it was powder based, it will cure and not dry so i would have thought after a week it would have cured sufficiently to require considerable persuation to remove the tiles. Just because it is sticking to the wall and not the tile doesn't indicate it is not securely fixed. When you remove a tile, the adhesive will come away from the weakest point of contact - in this case the tile back. Any adhesive will take several weeks to reach it's maximim strength, powder or tub, maybe you are seeing a problem that doesn't actually exist?

Keep us informed of how things are going, this is interesting.

According to the technical spec on that adhesive it will reach full strength within 14 days.... broken link removed

Thanks Dave I shall leave it all a couple of weeks...

Been trying to get the adhesive off the area that was tanked so I can put the tiles back on... Angle grinder, chisel and other tools later and I'm about half done.
