Floor in concrete optic / Screed floor

Hello After the completion of the screed, we are considering installing a so-called putty floor in concrete look. Unfortunately, there are not many providers or, if so, extremely expensive ones. If anyone knows an alternative, companies that are possibly top in terms of price-performance ratio, or if it's okay to do it "yourself" with instructions, etc., I would be grateful for any advice. Rooms and a bathroom are to be done. Maybe someone has taken this on themselves. I know there is a lot to consider.

Hello "Tommy77".
A conceivable scenario from my professional activity, based on which you can certainly decide whether DIY knowledge (and the occasional advice from the user section) is sufficient:
Even when installed by himself, according to complaints from the wife in a residential property I inspected, the new screed floor, installed by the husband himself in the domestic home, already showed signs of "snuffiness" after 2 months.
Not only had the appearance in the main traffic areas significantly suffered, but the surface of the floor had also visibly worn away.
What was now missing on the surface had settled on the furniture as a thick layer of dust, which did not please the DIY builder, especially not his wife.
The furniture along with the kitchen installation was therefore, in order not to further strain domestic peace, necessarily dismantled, temporarily stored in the garage and all available dry rooms, the screed floor milled back and everything newly installed by a specialist company.
This scenario is not fiction!
Regarding the matter, the following:
1. The price you complained about for such screeds usually stands in direct relation to the usability and thus also the durability of the building material.
2. It is not enough to study a brochure from the hardware store and then get to work. "Small details" like "ripening of the screed," correct stirring speed of the mixing device to avoid air bubbles, which otherwise settle on the surface and do not cause any praise from the wife.
All of this is important, usually unknown and foreign to the layman in theory and practical execution.
Even before commissioning a company to install such a floor, one should definitely (!!) inspect a reference project where such or similar decorative leveling compound was installed by the company. Because if one builder was already annoyed by the type of execution, then you don’t necessarily have to join in...
So: There are corresponding, highly priced screeds from various well-known suppliers, but also the necessary surface protection system.
I haven’t written about that yet, but this opens another door to domestic unrest during processing, because aesthetics are a subjective matter and one’s own execution usually enjoys special considerations depending on the success of the trade!

So the protective system is usually just a single sealing that can be applied several times. Much more so, the puttying itself is the biggest problem, where a lot can go wrong. That's how far I've gotten too. My concern is that I work with quality right from the start in terms of material and tools. The technique, as the name suggests, will be the decisive factor.

We are also toying with something like that. But there must be a reason why some companies decline outright with thanks...

We have also looked at such systems. We have seen some floors that (after a longer period) developed cracks or simply looked very worn out. Of course, this was only a small insight. For us, it was not an option anyway because we did not want visible joints. Then better to go straight for concrete and seal it with epoxy in the worst case. Such floors are also very expensive and not suitable for price-sensitive construction. Flooring in concrete look is also "special" and must fit the style. Starting from the house to the furnishings.

Why are such floors so expensive? Is it because such prices can be charged (because people cannot do it themselves) or is it due to the material/labor required?
