Exposed screed for rental apartments? What are the advantages/disadvantages?

Hello questioner. If I judge correctly, your question has not yet been answered properly. A "real" screed is called TERRAZZO. Due to the extensive grinding down to the support grain and the subsequent patching of voids, a price of €125/m² is certainly not too high. If you like a concrete look, it would be more sensible to grind the existing screed, which was certainly not intended for direct use, prime it, and have it resurfaced with an industrial filler. Afterwards, a pigmented sealant (gray) can be applied by rolling. Now to my assessment: Sealants are not permanent and are also not very mechanically resistant. With terrazzo you would certainly have mechanical durability, but the care must be constantly renewed. The effort to move all the furniture is really a question whether this is worthwhile for a rental apartment. And here we are already at the next problem: Every screed is firmly connected to the building component. And with that, this component, the screed, is the property of the landlord or the owner. Every (!) change made to it must be confirmed (in writing) by the owner before execution. Otherwise, we are in the area of "property damage," no matter how nice the floor may look. This means: If you want to move out in the future, the screed must be restored to its original condition. -------------- To sum it all up again, the only conclusion is: Better leave it alone!

Thank you for the answers. It is about the fact that we are renovating the apartments. So we are the landlords of the apartments.

A "real" exposed screed is called TERRAZZO.

Please excuse the inappropriate inquiry. Inappropriate because it has nothing to do with the question.

Isn't exposed screed rather the category for "ground floors"? This then includes variants:

[*]Terrazzo
[*]Mortar floor
[*]Microcement

Or, depending on classification, polished floor is the generic term. Then the subcategories would be as follows:

[*]Terrazzo - extremely even and precise on the surface
[*]Exposed screed - a more economical terrazzo
[*]Microcement - polished cement screed, mixed with additives

Or, according to DBZ:

[*]polished cement screeds
[*]polished concrete floors
[*]classic terrazzo

Please excuse the inappropriate inquiry. Inappropriate, as it has nothing to do with the question asked.

It is exposed screed (...)

Here we reach depths of information that are no longer meaningful for this public forum.
"Terrazzo" is largely clearly defined.
On the topic of TERRAZZO screeds, I have currently written a specialist article planned for the November/December issue of the "Inspirationsdatenbank" (FORUM publishing).
A terrazzo screed certainly falls under the category of "exposed screeds", whereas the other given terms do not!
“Ground floor” is not a generic term either but refers only to a post-treatment method after the hardening of a mineral component.
Regarding the reference to DBZ:
ground cement screeds are often called terrazzo, but not all ground cement screeds have this claim.
This is because the freely ground aggregate grain achieves a surface appearance that is essential and characteristic for terrazzo, which a standard screed cannot achieve. Furthermore, aggregates outside the mineral range can be added to the screed, such as glass shards or stainless steel chips. Then these surfaces are also ground and incorporated but have nothing in common with the classic term terrazzo, though they do with that of exposed screed.
It is not that simple—a walk/path through the definitions of mineral exposed floors!
