Hello everyone,
We are in the process of buying a house and are already planning the work we want to carry out.
To enlarge the bathroom on the upper floor a bit, we need to remove some non-load-bearing walls and replace them with drywall. We plan to install tiles and laminate flooring.
Removing the walls will create a gap in the screed (at least that is what I expect), which I want to properly fill and connect to the existing screed.
Can someone advise me on the correct way to do this? I don’t want a temporary fix that could cause cracks in the floor or walls later on.
Unfortunately, online sources often just suggest filling it with leveling compound.
I appreciate any tips you can provide.

Edge insulation strips are definitely recommended.
Since tiles will be installed later, tile adhesive is sufficient. However, you can also fill with screed concrete, cement screed, or anhydrite screed. Alternatively, the most expensive option is using leveling compound.
The important point is that screed should only be applied at a minimum thickness of 4-5cm (1.5-2 inches). It doesn’t matter whether it’s bonded to the old floor or laid on a separating layer. However, a polystyrene separation layer could reduce sound transmission to the subfloor, which might actually be beneficial.
Basically, there are hundreds of ways to solve this issue.
