I am new here and would like to introduce myself briefly. "Woman building alone," 50 years old, and I have been dealing with a complete renovation in the truest sense for the past four years.

Now my simple question: When is it possible to drill into a concrete screed to install a plug anchor?

To clarify, this screed slab separates two rooms that, forty years ago, were actually two separate rooms, and I have restored that division only in the subfloor. The top floor covering runs continuously from one room to the other. I understand that screed for flooring usually requires at least 28 days to cure. However, I only want to insert six anchors to fix a drywall frame. The two rooms will then be separated by a drywall partition with a round arch. I laid the screed three days ago. In wet, soft material, nothing holds well. Maybe someone here in the forum can tell me when this is feasible?

Thank you
Ulrike

Well, so far I have—according to this strange circle with a "thumbs up" in it—11 "likes." Luckily, I’m not on F.... But… is my question poorly phrased, or am I just not understanding it? On my “construction site,” I’ve come across some serious building defects. For example, there are only 3cm (1.2 inches) of polystyrene insulation and 3cm (1.2 inches) of screed. Now a new build-up is coming, and during this process, a surface heating system will be installed. Sometimes I could really use some help with what might seem like very simple questions to others.

You have 1 like from user @11ant ...
Unfortunately, I can’t help you personally because I don’t have any knowledge about this. I haven’t been involved for very long either, but @Nordlys might know something about it. He knows a lot. Maybe he can assist you further.

Once the screed has cured for 48 hours, it can hold a dowel. Do not confuse cured with dried.

I also believe hardness is not really the issue; I would be more concerned about keeping it "dry." Since the drywall is insulated with mineral wool, and moisture is coming from the building component below ... hmm

No, then everything is fine.

For now, only the single row of stud framing needs to hold, so I can divide the rooms and create some "roughhousing" in the separated half (removing the old reed ceiling, etc.). I still need somewhere to sleep. It’s already dusty enough everywhere. The screed will stay exposed to the "fresh air" for now and still has time to fully cure. Completely sealing off the wall will take a while. A full renovation right under your own backside definitely causes some chaos.
