How to patch up an old ceiling?

[Oscar-Daniel]

Hello
We have removed an interior wall and a small part of the ceiling. We have covered part of the ceiling with raw pine and have a small uneven gap left.



Any tips on how to cover this gap effectively?

Thanks for the help

That's not load-bearing structures you've cut away there, is it?

Remove the last board you put up, replace it with a wider one that you fit against the sloping ceiling.

It looks like the wall is reinforced inside the closet.

For the gap, can't you just saw a piece of råspont and put it there? That is, split it.
Are you going to cover it with drywall?

Had an engineer on site 😅

Remove the last board you put up, replace it with a wider one that fits against the sloped ceiling.

We did some calculations and figured out that we would come very close if we remove another of the original planks and then add two more rows of the råspont. However, we are confused about how to resolve the irregularity of the opening.

Yes, we will put up drywall - but I'm not sure how much the gap will impact despite the drywall.

The painter and carpenter will solve that when you have plastered ;-)
There are moldings that you can place between the wall and the sloping ceiling.

Yes, we will apply plasterboard - but we don't know how much the gap will impact despite the plasterboard

If plasterboard, I would loosen the top board and raise it as high as possible. The gap won't really impact when you then apply plasterboard.

The joint against the ceiling can be resolved with some angled cut plasterboard and some type of adhesive in the joint, like MS polymer. Regular acrylic or filler will probably crack. Perhaps paper tape and filler will suffice, does anyone else have insight?

If plasterboard, I would loosen the top board and raise it as high as possible. The gap won't significantly affect when you later apply the plasterboard.

The joint toward the ceiling can be resolved with some bevelled plasterboard and some type of glue in the joint, like ms polymer. Regular acrylic or filler will probably crack. Maybe paper tape and filler would suffice, does anyone else know?

I have seen hybrid sealant (ms polymer is an example of such) recommended earlier in the forum.

Why not attach a plywood sheet at the bottom?
