Hello everyone,
First, some details about my apartment. I am having an underfloor heating system milled in afterwards.
I consulted with a PCI advisor who recommended the following after milling:
1. Prime the milled channels
2. Fill with Nanocret R2
3. Prime the entire floor afterward
4. Install edge insulation strips
5. Level the floor with Periplan Extra
Now my questions:
1. I need to level the entire apartment. Do I have to separate each room from one another?
If I separate rooms with a wooden batten (at the door frame), for example, a 3mm (0.12 inch) height difference builds up compared to the next room. When I then move to the next room — let’s say the living room is finished, I remove the batten and the living room is now 3mm (0.12 inch) higher than the hallway. Since I no longer need to separate the hallway from the living room, will the hallway eventually level out with the living room? Or am I misunderstanding something? In the end, will I be left with one flat surface throughout the entire apartment?
2. If that is the case, how problematic is it if the living room section is partly cured already, and I then start the hallway so that the hallway and living room perfectly blend to one level?
3. Or do I have to separate every room from each other so that a slot essentially remains in front of every room?
4. How do you ensure precisely 3mm (0.12 inch) thickness, for example? I have seen several videos where the material is spread with a trowel or smoother—how do they know when they have reached 3, 4, or 5mm (0.12, 0.16, or 0.20 inch)?
Thanks in advance for the answers.
Regards, tester

Yes, you need to install an expansion strip individually in every room, including across the door frame.
I once worked on a room with a flowing screed, which could not be walked on initially. It is also advisable to use a compound that does not dry quickly, as there is a risk of it drying during application, which can cause unevenness in the floor.
Regarding the last question: the consumption is calculated based on x square meters... At least that has been my experience and knowledge.

karismasen21 Jan 2016 15:29I can confirm this as well... I installed about 180sqm (1937 sqft) of self-leveling compound. I calculated the amount of kilograms or bags needed for each room based on the manufacturer’s instructions (the data for the leveling compound was very accurate... I always had just a minimal amount left in the bucket).
I did the same with the primer... but strangely, the manufacturer’s specifications didn’t match here—I only used about half.
I didn’t separate the transitions between the rooms. As ypg mentioned, edge insulation strips need to be placed along the walls... luckily, I still had mine from the screed phase.
Regarding your point 1: Is "Nanocret R2" some kind of flow resin? I did it without—just poured in the leveling compound and that was it.
Oh yes, and before laying the floor, make sure to sand the whole surface well! It takes a bit of practice to get the hang of it... the machine can be tricky to handle.
