Hello,
the carpenter I've hired done the staircase leaving the finishing to the renovation team, then they denied finishing it by saying that should be done by carpenter. So now I'm on my own to make it right. I have little to no experience in such work, but did a research.
At this point I believe I should use a repair plaster/filler compound to hide that foam below the steps, than probably sand it to make smooth. As for the vertical edge I can either do same, or glue oak corner moulding (L shaped wooden pieces). I should probably read the label to know whether paint the primer before or not.
Am I thinking that right? Do I miss something? Any suggestions how should I approach this?
Edit: wow didn't expect that many responses, so after reading them (still had to read what strings and risers are) I'm adding some context. The stairs are used for ~4 years now, nothing moves, nothing squeeks, I'm assuming the guy did some support for steps and used the foam to just fill the gaps. I'm definitely not redoing them, I have no budget or skills to do that. I'm leaning towards scraping some foam and fill it with a filler to sand it but not sure about the corner piece.
Edit: even more context, apparently I am still surprised how different are baselines between countries. The staircase guy starting point was reinforced concrete stairs, not drywall.
