Incorrect Adhesive Used

[Kemp8094]

The fact that it's not grouted is a plus, good call! I realise it's not ideal, but if I was gonna chance it like you've suggested, then I'd wait til you return then turn the heating on to its minimum then increase the temp by 2degrees a day to the maximum. Leave it full blast for 24 hrs and then reduce it in the same manner until it's off. Let it cool completely then turn it back on again. Then see what state the floors in.

What is the maximum? The thermostat seems to go up really high? It's 150w kit and just wires, not matting. I haven't had it up really high just noticed that you seem to be able to keep upping the heat.

The grout I got is flexible it's from BAL.

.... with flexible grout!

It wont go past a certain point. Defined by your own floor there's no rule for it per se.

But just when it doesn't seem to go any warmer when you're doing the 2 degrees a day thing, stop and keep it at that temperature for 24 - 48 hours. Then slowly down a degree or two a day until it's always off.

Then use it as you wish.

I'd perhaps always tease it on and off so it's not a big shock going from cold to hot which is when it'll crack or whatever might happen.

Every ufh system is different, @Dan may be able to give u specifics on that.
Flexible grout is good. The Bal goes off quickly, do small areas at a time.
Dan is correct u probably will get issues but if you're gonna try leaving it then u need to give urself every chance.
You will soon tell if it's failing, the grout will crack first.

I'd suspect if they used AD1 in standard grout, it'd be super flexible and not crack, but the adhesive still might.

Best to always increase it only be a degree or so a day to running temperature in the colder months.

Never just whack it on full and go for a shower etc.

......ok what I should have said was, the first visual sign will probably be grout cracking, 😀
Just feel like I'm digging a bigger hole here! Haha

It's in my living room so no danger of that.

I will see how it goes. As it stands it's ok but you never know when you turn the heat on. I hate removing grout!

 

[Dan]

I'd suspect that if it goes wrong, you wont just be removing the grout so you don't need to be too careful if it comes to that.

I will keep you guys updated and post after I get back from Greece as to whether it has worked or not.

If it has worked out this may offer hope to others that have cocked up like I have. Bollox!
