[Tiler Bristol]

Preparation hasn't been done correctly for whatever reason but it can be investigated and solved. This looks like a good read if you haven't seen it Do Tiles Crack With Underfloor Heating? - besthomeheating.com - https://besthomeheating.com/tiles-crack-underfloor-heating/?utm_content=cmp-true

Assuming the adhesive and grout used was suitable, ie. Flexible!

@Anthony and @MrKnowItAll - So the floor that was put down was anhydrite gvylon liquid screed floor.
My suspicion is that the tiler didn't apply a primer to the floor before putting down the tiles.
Leaves me with 100sqm of f*ck up. And the tiler won't admit his mistake. He will say I didn't supply him with the primer.

The grout and adhesive used was suggested by TilePlus was a Palace Chemicals standard stuff. They aren't accepting that wrong advice was given when they were told what sort of floor it was being tiled on.

It sounds like a poorly prepared calcium screed. Sorry this page is jumping all over the place

Yep, I’m getting it jumping all over the place too.
Makes reading more than 1 comment almost impossible … not a great 1st impression of the site …

Was everything else supplied to the tiler? I.e. adhesive, tiles, grout, silicone etc … was the tiler asked to supply anything himself?

Hi Alex, everything was supplied to the tiler. We did ask him if he needed anything else given the information about the floor. He didn't think a primer was required.

Sorry, sounds like you might be right … no idea why you wouldn’t want to put a primer down on a new surface like that … bound to be some sort of residue / powder somewhere as it’s dried & for the time it takes to apply a primer, even with a brush, it’s not worth the potential impact of not doing … but if you didn’t provide it, that’s what he might say, but then you did check with him specifically & he said no …

You might want to get someone in to look at it & check, rather than just going off the advice here - there might be an underlying cause that’s nothing to do with the tiling (although that doesn’t sound likely I’m afraid).

Took a few up now. First one was 112 m2 took 2 of us 75 minutes to take it up, with a hand full of adhesive left on the floor!!

Someone has looked at it and said it is due to the primer not being put down. The tiler isn't taking any responsibility to the point of ignoring my calls. I am lost at this moment.
What can be done? The other guy mentioned epoxy grout as he thought the epoxy might hold the tiles stronger. The gap between the tiles is 2m which won't be enough to drill and pump fix a floor solution. What do you recon?

Hey Anthony, is it worth re-grouting or spreading epoxy over the tiles to hold them down before we start taking all of 100 sq m of tiles?
