Tiles coming up months after installation

[Mr T]

You didnt mention the floor being primed... Maybe thats the reason the adhesive wasnt stuck to the floor?

 

[Ian Vinton]

The heating was not switched on for two weeks for the first property and 1 week for the others.

The floor was primed, I saw it done. Given two coats according to the tiler.
However, the tiles were laid when the primer was still tacky, is that right ?

Most tile adhesives (cement based ) do state no primer ... this might explain the lack of bonding ... but still does not make the installation of tiling direct to chipboard correct ..

Have you called the tiler back Ian.. ?

 

[Andy Allen]

depends on the adhesive, some don't recommend priming the surface to be tiled..

I have had him back twice and he is back tomorrow to strip out the tiles and do a temporary (as that is all it will be) repair in one of the other properties. He is not sure what the problem is, he has mentioned wrong adhesive supplied and the supplier reckons there has not been enough adhesive used.
I am at my wits end as we need these properties let, we currently have one unoccupied, where we found the problem and one being vacated in 4 weeks because of the problem.

Ian it is down to the tiler to ensure the correct adhesive is used , so he really should not be using that excuse..???

Was the heating banged straight up to it's highest heat or was it turned up gradually.....

As you've discovered from the earlier replies, several things either individually or collectively lead to the failures.
1. Tiling direct to chipboard - not good
2. Tiling to a floating floor - not good
3. Using a tiler who thinks doing the above is ok - not good
4. Adding heat into the equation - not good
Had you asked me to quote for this job, I would have politely declined.
Whilst I always want to see tiles used ahead of other finishes I think on this occasion I would consider an alternative.

The heating went on at at 15 degrees for a couple of months and then up to 18 background, and the up to about 25 degrees
