I am looking for a solution to the following problem. In the stairwell, I have a material joint on the sides/walls of the stairs where there is wood on the sides of the stairs, and then it transitions to a newly plastered wall. However, the material joint is not in a straight line but curves like a banana (if you know what I mean...). I'm not sure about the radius of the curve, but over 3 meters, it bends maybe 10-15 cm. The materials wood/plaster are in flush alignment. The plastering is done very precisely, meaning there's only a millimeter gap between the materials. One option might be to caulk this gap, but it seems very difficult to make it hold and look nice. The wooden part of the stairs is going to be lacquered, while the plaster is to be painted. Therefore, I have considered some sort of trim to cover the gap (like screwing/gluing it there). I have thought of, for example, a 20 mm small trim or a planed board 20 x 8 mm. The problem is that the trim needs to be bent the 'wrong' way, so to speak; it’s not so easy to arrange. Bending a trim around a round corner is one thing, but in my case, the trim has to be bent the other way, and the wider the wooden trim, the more impossible it becomes to bend it as I want. So, I would need some kind of trim that is bendable in that direction. Does anyone have any tips on a solution?
There are plastic moldings available for purchase. These are softer and more flexible than wood. I installed such moldings myself in the joint between the ceiling and wall on the stairs down to the basement (also a lot of strange curves). It was just a matter of nailing them down and bending as needed.
Once you paint everything, it looks like any wooden molding.

Thanks eviljava! Something like that might work. I've surfed around a bit looking for something like that but haven't found anything suitable in profile. I would like the profile to be like a foglist or a completely rectangular list, e.g. 8-10 mm x 15-20 mm.
Thank you eviljava! I went to Bauhaus this weekend, exactly what I needed. They were called Primo lister.

): In my case, the stringer (in wood) is built flush with the wall (in plasterboard) so there's no edge or similar on the stringer where you can place a horizontal molding. If you understand what I mean... Old house with a custom-built loft ladder...

Think boat building!
You can try to moisten your strip, clamp it between two boards (the strip on its edge between two boards lying side by side), and then bend the boards in the "right" direction and leave it like that for a few days in the garage. That way, you should have achieved a long-term deformation of your strip in the "wrong" direction.
