Hide gap in ceiling after removal of interior wall

[Gjutjärn]

Hello! How would you go about easily hiding this gap between the ceilings? There was an interior wall there previously. I've considered having a scotia molding, so if I have to use a board along it or something similar, it shouldn't be thicker than the edge of the scotia molding, I think, to avoid it looking strange? I've considered the Byggmax scotia pine:

And that edge is about 8mm, so a board thicker than that would look odd. What I've done myself is filled the gap (there was a piece of wood along it) with a ceiling piece that I cut to the right width. I'm wondering if it's possible to putty, sand, and paint it, perhaps? It might not be as smooth as the rest of the ceiling, but at the same time, it might be something no one else will notice or think about? What do you think?

Appreciate all the help!

I think it will be excellent. Just as you say, no one stands and stares up at the ceiling that often. As long as it's reasonably smooth and the same color over the whole ceiling, you don't think about it. Besides, it doesn't matter if you can see that it was two rooms.

Thanks for the answer. Were you thinking about what I wrote about filling, sanding, and painting? What filler should I use then? Not my area at all

Thanks!

Regular wall filler will do just fine. If it's very deep, you can fill it a bit with gypsum filler, or even husfix. But probably that's not needed. First, fill the gap and let it dry according to instructions. Sand it if necessary. Then fill over it again to make it even and sand it. You might need to fill a bit more and sand again. Then paint what you filled and try to get some texture in the paint so it resembles the rest of the ceiling. After that, paint the entire ceiling. Usually, you need two coats of paint. When the entire ceiling is newly painted, you'll just think it looks nice with a freshly painted ceiling.

Regular wall filler should work fine. If it's very deep, you can fill a little with plaster filler, or husfix for that matter. But it's probably not necessary. Fill the gap first and let it dry according to the instructions. Sand if needed. Then apply more filler so it's even and sand again. You might need to apply more filler and sand again. Then paint over the filled area and try to get some texture in the paint so that it resembles the rest of the ceiling. After that, paint the entire ceiling. Usually, you need two coats of paint. When the entire ceiling is freshly painted, you'll just think it's nice to have a freshly painted ceiling.

Awesome, thanks for the help!
