Tile Crack - Advice Needed

[Time's Ran Out]

Your ufh can't get too hot to crack a tile, it's what's under your ufh that can cause a crack.. Seems strange to me that the ditra is at the bottom of the makeup?

I assumed the weyroc boards were just there for protection and not fixed on top of Ditra.

 

[Thoughts]

Great, I'll put it back on then, thanks! I was so scared I'd completely messed up my bathroom by putting it on too high a temperature, so that's at least a relief! Ok, this again might sound really stupid but the Ditra is the orange stuff right? The boards on top of that were just there so I could use the toilet before they did the next stage. I do feel very confident that the people that fitted it were good, I can't really imagine it's anything they did. I'm going to hope that it is this glaze problem and that I have just been unobservant up until now! I am so appreciative of all your time replying to me!!

The ufh heating should really have been turned on slowly and commissioned over 6 days and not ramped up to full straight away, but you might have got away with it, touch wood (not ply) its a fault in the tile glaze 🙂

 

[Thoughts]

Thanks!! I hope so too! If there were any problems with this commissioning failure by myself, would they already have surfaced, or can it take time for them to show?

Your tile/ufh installer should have instructed you on starting up the ufh..
Like you say it may have been there a while but usually faults take time to develop

Ok thanks, do you have any idea how long I need to wait to be sure I'm safe from any side effects of not having done this? Also one more question - does this only need to be done when it is first installed, or would I need to do it after a period of non-use (I probably won't use it over the summer for example)

On the initial start up, adhesive needs about 2-3 weeks to cure properly...then a couple of degrees a day, running at temperature for about 3 days, then slowly bring it down per day to be sure.

 

[Thoughts]

Thanks, yes I didn't do this. What I'd like to know is, bearing in mind I didn't do this in late November, by what point in time would it be expected that any problems that were going to arise from it, would have happened?

How long were they down before you turned the heating on ?
