Would you consider this quality work?

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)

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.

I think that's the guide with gypsum too

I thought the gypsum was far longer from my understanding.

I'm under the understanding that it's 1mm per day up to 40mm and 1mm every 2 days thereafter ?!

Just had the same problem on a anayldrite screed.
The front door was leaking for 2years since I laid the floors (over 100m2) about 2m2 became lose and grout cracked.
Me and the owner lifted tiles , tiles came away clean, I'd back buttered , back buttering was still on tile and addy on the floor.
Addy was dusty and damp.
Looking at your bifolds and outside , could water be penetrating under the sill ?

Hi Antonio,

I think it's Bs (British standards) in the U.K. I'm not sure if uni is the same?

then, I am informed.
UNI are Italian standards, written in collaboration with ASSOPOSA.
ASSOPOSA is like TTA English.
TTA and ASSOPOSA are members of the EUF, federation associations tile installers. therefore, it should be the same. there may be slight variations, for example in the laying out of wood, or on substrates anhydride, which here are almost nonexistent. I think
