Cheap ceiling that isn't plaster?

Halfway

What do you think should be used to fill the gaps in the wall? Regular putty or something like gypsum plaster

Can't you consider a ceiling moulding then? A small cove moulding would cover that.

Both will probably do the job! But it's unnecessary to buy a large bag for the small gaps, but if you have it at home, that's great! Otherwise, filler is convenient, the downside is probably longer drying time and it might need to be done in several layers if the gaps are deep.

(not a pro)😅

Can't you imagine a ceiling molding then? A small hollow molding would cover that

Of course 😀 Just need to measure, the plaster has come off differently everywhere. But maybe there are large ceiling moldings haha.

Perfect!

Well, it's certainly fine to call a 4"x4" a list if you feel like it?

Hello everyone, the cast is done and tomorrow it's painting time

 

[naikon]

Alright, I am basically done with this project. Painted twice and new lighting in place.


Let's see what I'll do with the corners, it almost seems easiest to put in coarse filler instead of spending time and money on ceiling moldings (which are glued?).
The appearance isn't exactly a priority... Mostly just to avoid getting things like spiders in.

Thanks for all the help I've received in the thread. People who find the thread later will probably scratch their heads when they read the thread title and wonder why there's drywall on the ceiling 😁

We'll see what I do with the corners, it almost feels easier to use coarse putty instead of spending time and money on ceiling moldings (which are glued?).

Latex sealant could be an option too. It's easier to fill the corner with a glue gun than with a putty knife.

Latex sealant can also be an option. It's easier to fill the corner with a glue gun than with a putty knife.

Yeah, it would have been nice to just use the caulking gun. But maybe a bit difficult to shape perfectly?

But maybe a bit difficult to shape it just right?

Do it in (at least) two rounds. First, fill the hole approximately to a 90-degree corner. Once it has set, make a neat "finger pull" on the finishing joint. I would probably fill the plaster drop unless it is entirely negligible. Hard to see the depth in the picture.

Apply in (at least) two stages. First, fill the hole roughly to a 90-degree corner. Once it's set, make a neat "finger run" on the final joint. As for the plaster release, I would probably apply filler unless it's completely negligible. Hard to see the depth in the picture.

Thanks! In that case, I think I'll fill the roughest plaster breaks with filler and then apply the sealant as you suggest 🙂

 

[Avemo]

Thank you! Then I think I'll fill the roughest plaster releases with putty and then go with sealant as you say 🙂

In the picture, I think the cavities look too large for putty to be effective. It can't handle thicker layers than sealant, I would say.

In the picture, I think it looks like the cavities are too large for putty to work well. It can't handle thicker layers than joint compound, I would say.

Thanks for the tip!
Alright, otherwise I thought coarse putty was good for filling voids. What are you thinking for filling? Foam sealant or latex joint compound?

 

[Avemo]

I was thinking about latexfog. It will shrink if you fill all the cavities with it. But filler will crack and I don't think that's better. Foam sealant could work. But it's quite messy and troublesome to deal with in such places.
