The only test I've done is laying a dpm on the floor with planks of wood on either side to weigh it down and checked if theres any condensation underneath 24 hrs laterAlso have you moisture tested
Are those small patches of laitance the lighter shades of the floor?If you are not sure sand it again? It's you that needs to be comfortable that its properly prepped. I can say there is some small, patches of what looks like flaky laitance there but whether its enough to cause you an issue I dont know from photos.
Then you need a proper test. Are you DIY tiling or getting a contractor inThe only test I've done is laying a dpm on the floor with planks of wood on either side to weigh it down and checked if theres any condensation underneath 24 hrs later

yes it does... without wishing to be in any way harsh - it tells me that you don't know what you are looking at. to be dry the screed needs to be below 0.5% moisture or 75% RH. when it was made in the factory it had perhaps 13% moisture so your 30% is clearly wrong.How do I go about getting it properly tested?
I have a humidity reader which measured relative humidity at 30% when I had the ufh on. Does that say anything?
The 30% was the RH in the room once the ufh was running and when ufh was turned off the RH crept upto 60% and has been consistent at that figure. When using anhyfix adhesive isnt the figure 85% RH? I maybe wrong.yes it does... without wishing to be in any way harsh - it tells me that you don't know what you are looking at. to be dry the screed needs to be below 0.5% moisture or 75% RH. when it was made in the factory it had perhaps 13% moisture so your 30% is clearly wrong.
