Hello everyone,

firstly about my apartment. I am getting a retrofitted underfloor heating milled in.

I consulted the PCI advisor and he recommended after the installation

1. to prime the milling
2. then to level it with Nanocret R2
3. and then to prime the entire floor
4. to install edge insulation strips and
5. to level with Periplan Extra.

Now my questions regarding this.

1. I have to level the whole apartment, do I have to separate each room from each other?
If I separate with a wooden beam (at the door frame) for example, a 3mm height difference builds up compared to the next room. If I then change rooms. The living room would now be finished, I go into the hallway, I remove the beam and the living room is now 3mm higher than my hallway. Now I no longer have to separate my hallway from the living room, so my hallway will then level itself to my living room in the end? Or do I understand this wrong? In the end, I then basically have 1 level surface in the entire apartment?

2. If that is the case, how problematic is it if the living room has already partially hardened and I start with the hallway so that the hallway and the living room perfectly blend to one level?

3. Or do I have to separate each room from each other so that a gap basically forms in front of each room?

4. How do you manage to get exactly 3mm height, for example? I have seen several videos where they spread the material with a trowel or squeegee, how do they know that 3, 4 or 5 mm has now been reached?

Thanks in advance for the answers.

Regards tester

Yes, you have to set a border strip across each room individually, including in the door frame. I once worked on a room with flow screed, which was then not allowed to be entered at first. It is also advisable to use a mass that does not dry quickly, as there is a risk that it will dry while spreading, causing you to pull floor waves. Regarding the last question: you calculate the consumption for x sqm... At least that was my experience or my knowledge.

can also confirm.... I installed about 180 sqm of self-leveling compound myself. I calculated how many kg or bags I would need for each room according to the manufacturer's specifications (the information from 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 half.

I didn't separate the transitions between the rooms. As ypg mentioned, edge insulation strips must be placed along the walls... luckily I still had mine from the screed

regarding your point 1. "Nanocret R2" is that some kind of flowing resin??? I did it without... just self-leveling compound and that's it.

oh yes, and before laying the floor, make sure to sand the whole thing nicely! You need a bit of practice until you master this thing... they basically take you for a ride
