What to do and why

[TandS]

What do you mean by commissioned sorry if that's a stupid question

 

[TandS]

Not sure please bear with me everyone I'm not total sure how to use the site computers ain't my thing sorry

Right It was turned on to soon so we can only point the finger towards that. I always say 2 weeks drying time before turning the heating on and only to increase the temp by 3 or 4 degrees per day.

 

[Concrete guy]

No it wasn't but it was turned on the next day as far as I'm aware

That's your problem. Should be left 28 days before it's switched on (or always used to be).

What do you mean by commissioned sorry if that's a stupid question

switched on, run and tested far more important with water UFH but still prudent with electric as long as it's been screeded in.

Have the tiles de-bonded from the floor or just curled at the edges etc.. ?

 

[TandS]

I believe he used evo stick floor tile adhesive which he was told was suitable for underfloor heating

 

[TandS]

Just two rows look like they have de bonded they have risen up from rest of floor like a bow

 

[Gazzer]

Well they say anyone can tile and here is the proof....No they cant !

 

[TandS]

What is the solution can the two rows be replaced they are about centre of the whole floor

 

[TandS]

I advised him and gave him the number of a local tiler but if my advise is not taken what can I do at least I can now tell him where he went wrong thank you to all of you who have replied I'm very great full and will stick with my moto horses for course always use a professional

I always leave the customer with clear instructions not to turn on the underfloor heating for a minimum of two weeks after the last tile was laid and then only on the lowest setting increasing by 1 deg each day until max temp reached. But as above unfortunately more info needed to give more advice.

 

[gamma38]

If the wire was covered with self levelling before tiling you may have a chance of removing them and relaying without damage to the heating, if it was tiled straight onto the wire then your in the proverbial.

Sounds like "tenting".

Lack of expansion,

and the UFH turned on and too high far to quickly.

did he leave any gaps between the ply sheets or were they butted up hard to each other?
