95sqm onto screed with water based UFH - recommendations?

No it would be perfectly reasonable to expect it to be dry after 9 months but things can get wet as well as drying out. Depends on environmental factors, floods, spills etc. never assume is my motto these days.

What do you mean "at last" ?

well some screeds can draw in a lot of moisture from day to day be ok one day to tile but not the next depending on weather conditions and are the windows fitted ie air tight .so you should test again the day you start tilling .and all the way throught .on some screeds .

You mean calcium sulphate screeds I presume. All screeds do the same thing in terms of equillibrating with the atmospheric conditions. It's basic physics. At the dry stage of the screed It's often a counter intuitive process though. As the atmospheric moisture content goes up the moisture level at the screed surface actually tends to go down as the high vapour pressure in the air prevents moisture coming out of the screed. That's why you can see hygrometer readings change dramatically when the screed and the air are nearing equilibrium. We are shortly to publish a report independently derived about drying and measuring screed moisture which wil hopefully clarify a lot of the myths about drying times and such likes.
