[Solved] Cement Screed Issues in Apartment: Large Slab, Cekol ZW 04, Threshold, Grinding vs Forging

I know this is a very old thread, but maybe someone else will answer this question to me: I put a cement screed in a block of large slab, probably Cekol ZW 04 a month and a half ago, unfortunately it turned out that there is too much material, as much as about 370 kg because such Danube waves were . In the highest place the spout is about 5mm but in the lowest one almost 3 cm. They say that this is not a problem but I think (feminine intuition) that it is all too heavy and I will not put the spout in the whole apartment. Now I have a threshold of 3cm and I do not know how to get rid of it. the only solutions are forging or sanding this new spout. But if it is forbidden to forge in blocks from the hole plate, all that remains is the grinding of this screed? (apparently milling is more stressful for the building structure than hammer forging) but grinding can be? "Professional" claims that he can choke it and put a new spout. But I'm afraid of this forging. Like the new spout is to forge and not the old one but forging is forging, shocks are shocks. Please, if someone reads this for a quick answer because the matter is urgent. Regards

The screed is not a load-bearing structure of the building, so its forging does not matter for the security of the building. However, its weight and yes. It depends on the surface on which it was spread.
But almost 15 bags of screed? a lot .... for an apartment.

Thank you very much for your answer. I understand. So everything that concerns the prohibition of forging in blocks made of hole boards are bearing walls and the huge slab itself? And for example terrazzo in bathrooms? If I want to forge it in the future, I can damage the building without any risk? Is it the same as for a spout? So you advise to eliminate it? Forge or grind? Doesn't matter? Such were the differences from the window to the door and in the middle of the boat and it came in, exactly 15 bags. Is this a lot? Am I burdening the building very much? Room 12m2, third floor.

In a block from a large slab you must not violate ... slabs. That is walls and ceilings.
If someone has plastered the interior, it is possible to intervene in the plaster, while prefabricated slab concrete cannot be used anymore.

In my opinion, this is not a supporting or supporting element of the structure.

I am an electrician, I will have a designer on hand tomorrow. But since it stands, it will rather stand, this building.

You need to look for some supervision inspector in this or other cooperative - currently
something uplifting.
I did the screed with excellent means - but because of the temperature -
waves were formed. It was forged and the whole was made using concrete made without accelerators, etc. The most common concrete. After that - all the substrate was tied under a thin film. And after curing, there was a problem waiting to get the right one
humidity - it was supposed to be concrete laid under the parquet. For this purpose, the parquet master provided me with a meter measuring the humidity of the ground. Then, during the hardening of the substrate - on the phone - at weekly intervals you had to watch over this drying.
And the mean crooked concrete as quickly as the mean one did - it also landed quickly
It was possible because it was freshly made ... and the crooked result had to be quickly removed - to avoid even more work ... The parquet was made after measuring that the concrete substrate had the right humidity.

Thank you very much for your answer. The Lord has helped me a lot! I don't panic anymore In the end a guest will come and say that it sucks and where there is an old spout it will sand and put a new self-leveling. I hope that it will be good and that I will not damage the structure of the block or the ceiling of the neighbor. Regards

That mine was also self-leveling .... but it leveled too quickly. Simply - there must be some fast mechanical equipment to constantly knead this mortar and put it and spread it out evenly. It is better to prepare for this operation longer than something in make and improve the march. The number of employees is also right.
As for the neighbor, ask about any stains on the ceiling - some flooding -.
For me there is a ground floor - I could easily "watch" any gaps and seal ... Regards.

I think that the assessment by a professional will depend on whether it is impossible to cut those humps and
straighten the whole thing "flat" ... With the same mortar ... complementing the deficiencies. It all depends on the professional's assessment and ... the quality ... of what has already been done.

I forgot write. The screed was scoured and the old one was sanded. It's new now. It is true that with a light boat in the middle but tolerable. Thank you all very much for your help. Regards : )
