[One Day]

Threads like this really drive it home how much responsibility and pressure is on our shoulders

So you share it out - a bit to schluter, a bit to tilemaster, a bit to bal... Get everything recorded, keep emails, photos etc.
Follow the rules and prove that you did.

I'd recommend any new tilers read this thread for sure as it just shows how much can go wrong.

I'm amazed its gone wrong a second time - to have a bad tiling job was bad enough but to have them lifting now is just unbelievable.

Drying tims for screed we were told 2mm a day for x depth and 1mm for anything deeper. But we were well within those times for the depth we had especially as we forced dried it and used dehumidifiers.

Its also funny that last time the tiles stuck like glue in the only room without UFH - so I think its more likely down to the adhesive not getting on with the heat than the screed being damp.

@Ajax123 - Alan Jackson might have some valuable insights into just how long these screeds can actually take to dry.
I must admit - even years later I'm still wary of them giving false readings which is why I always use Ditra as another line of defence, allowing that last bit of moisture and vapour to escape....

Good shout, the man's an encyclopaedia of all things screed related.

That would be 1mm a day and over 40mm 2mm a day but that would be a sand/cement screed.

I think that's the guide with gypsum too

Why was he using quick set.
Did he mix 2 different adhesives (quick set with normal can give strange results)
Did he mix half set adhesive with more water because it has dried out (meaning the adhesives chemical reaction had already happened so what you end up with is chalk)

"Did he mix half set adhesive with more water because it has dried out (meaning the adhesives chemical reaction had already happened so what you end up with is chalk)"

I'm not sure but that is interesting - I don't think he did but it is certainly chalky now.

Could that mean it would stay damp still as well?

He didn't mix two types of adhesive though - it was all csa flexible stuff.

can I ask how you clean your tiles, mop and bucket? Steam cleaner?

if the tiles had failed and grout cracked cleaning water could be the cause of the damp under some tiles, leading to adhesive breakdown.

Exactly what I was thinking.
Has water managed to get into the grout and adhesive from above?
Cleaning/dog water bowl???
This thread really does get you thinking tho. Serious responsibilitys we have.
