Issue with Granfix Flexible Fastset

[Brian the Tile]

as for getting the rep out ,well if they are anything like bal you wont get far with the complaint ,athough i have only had two minor problems with bal, myself and the customers conserned got letters back that even a top scientist couldn,t even understand on an a 4 sheet of paper,but broken down all it said was that the product was up to bs and the wasnt prepared to help,that,s why i dont use bal anymore ,idiots

Brian i ment a technician for the under floor heating. Not the adhesive.
I don't think this is an adhesive issue

Thank you all for your replies!

I can't be sure about the preparation the customer did. It was ok but can't be sure unless looked at.

I have some images of the tiles and adhesive. Like I mentioned before I layed the tile by adding the adhesive first to floor and then to back of tile to create a full bond. The customer said the tiles felt loose and Photo 1 shows how the tile looked as I lifted it. Photo 2 is the back of the tile, you can see the adhesive hasn't bonded to the tile at all. You can also see the cracks in photo 3 and 4 but they don't follow the lines of the under floor heating.

Apparently a rep is due to check the job from Granfix but not sure when this will be. I see somewhere about a possible change in formula in the adhesive due to EU regulations but can't be sure on this. A sample was sent from this job for testing and test came back ok, but i think they were testing to see if I added anything to the mix to make this happen, but I did not do this.

What do you think?

I don't think the images appeared properly. Ashame as it shows how the tiles look as they were lifted.

Not sure how I can insert them so you can all see?

I have a rep coming to have a look tomorrow so I can update on any answers.

I spoke to the Under Floor Heating company which was WarmUp, and they have said that turning the temperature up so high would not have affected the tiles in that way, and would be down to adhesive failure.

Thanks,
