Looking for experiences with exposed concrete stairs

I thought that if you want an exposed concrete staircase, a precast staircase is rather recommended than a cast-in-place staircase? That is what the construction company also told me. I have no idea how it is made.

Yes, the surface of prefabricated parts is improving. However, you have a joint at the top that you need to deal with.

There are two different ways to manufacture a staircase in the factory. For exposed concrete, it should be "negatively formed," which means the future underside is on top during production. This must be taken into account when ordering.

Best regards

That should be standard practice, since of course you want to see the smooth formwork side
From "below," the staircase is then obviously relatively unattractive.

Which joint do you mean?

Probably the joint at the connection to the coverings of the respective floors. But strictly speaking, you also have that with cast-in-place concrete, at least the transition and material change.

We haven't progressed further with our staircase yet, had to postpone it to not block the stairs. But we'll do the cosmetics ourselves.

Yes, exactly. If I manufacture them using in-situ concrete construction, I actually only have one joint, like at the room transition in the heated screed. A precast element is usually acoustically decoupled via, e.g., Schöck elements. This joint is 1. wider and 2. fully accommodates the tolerances. If I now have no covering on the stairs, it is harder to visually bridge this joint.

Aha, so I will ask again whether the stair is wired negatively, but it would somehow be assumed if I want an exposed concrete stair. The joint is then between the stair and the flooring on the floor or, in my case, also at the landing, right? I need to address that again as well. @Pfadfinder 87 it would be nice if you could share your experiences when you use Beton Ciré and do it yourself, how it works out.
