"I've just worked out what the best bit about a regrouting job is; going home"

Brilliant!

Another brilliant blog ...

 

[The Legend; Phil Hobson RIP]

As above brilliant, I,ve been bangin on about thermal shock/ bring up the heating slowly. He sounds just like me, one job cost me two days labour, because the customer didn't listen to me:mad2: Keep up the good work Adam

Hi guys, thanks for posting this vid.
This one has really confused me - the tiler was obviously half decent, knew enough to apply a tanking system in the shower (even though it's failed and we've isolated an area where it's leaking), also knew enough about UTH to fix Ditra mat and yet installed a thermostat inside the bathroom (unbelievable!!). The joints on the walls are excellent and for a polished 60x30cm it's very flat but the setting out is amateurish at best.
I just don't understand how someone who obviously has some talent for the craft can make such basic balls ups.
:mad2:

excellent blog how did you come to the conclusion its thermal shock?

Hi mate, I take it you are not a fan of this wrap around method of setting out. What is wrong with good old centering walls, to give a pleasing effect. that job looked (pants) Who teaches this?:mad2:

Gary when the heating is commissioned, if it is not increased by no more than 5deg in any 24 hours, then held at optimum temp for 2 days. Then reduced again by no more than 5deg in any 24 hours, you risk thermal shock. You can tell if this is the problem, if the tile leaves the bed clean ( with just a sand paper feel of adhesive residue on the tile) then this is typical of thermal shock. As I said, I have been there:incazzato:

I understand what thermal shock is and how its caused, its just the stress cracks are very similar with deflection, I noticed that the cracks followed the lines of the ufh and assumed that is how you decided it was thermal shock, I dont disagree with you ,i was just hoping that there was a bullet proof way of telling whether its deflection,thermal shock or under rated adhesive

It's the residue on the tile, and the fact it pulls from the adhesive pretty clean. Deflection would have bits of adhesive on both the tile and the substrate still, right?

Bang on Dan

thermal shock or deflection?

 

[Dan]

Looks like thermal shock.

Did the tile break like that as you lifted it up, or was it already broke? Could be a bit too much for thermal shock if it was broke like that on the floor, that could suggest deflection. The tile must have stuck if it's sort of smashed? Possibly over time as it's being walked over?

thermal shock or deflection?

Always hard to call, I have been told by some how easy it is to differentiate between thermal shock/ deflection/ lateral movement, from tile samples in a laboratory. But others are of the opinion that there are always gray areas, so how it would stand up in a court case I'm not sure:yikes: It's frightening.:incazzato:

 

[Dan]

Best way it'd stand up in court is to prove if the floor has deflection, and then see how it was dealt with if it has. If it doesn't have any after lifting all the tiles, chances are, it'd be thermal shock.

Though the pics there show limited adhesive on the tile, the cracks seem to follow suit with the substrate which could suggest deflection perhaps? The tile must have cracked when the floor did. And as you say, the adhesive becomes loose with thermal shock, and although it could crack the tile, I don't think it'd follow the substrate quite so accurately.

Could be the beer talking. :drool5:
