The building supply store gave wrong advice about drywall in the ceiling, is it ruined?

[Emmazk]

Hi!
I was going to install a ceiling for the first time and framed with battens, unsure of what type of plasterboard I needed, so I went to a building supply store for advice. I explicitly told the person who helped me several times that I wanted a smooth ceiling, meaning I planned to fill the joints.
He showed me a board he called "ceiling plasterboard" that was supposed to be easy to put up, with slightly beveled edges forming a small V between the boards.
I mentioned that I had heard you need a wider gap to be able to fill it for a smooth ceiling.
He said it wasn't a problem, just fill the joints and be happy, basically.
I have just installed the entire ceiling with great effort and then started looking into what kind of filler I should choose.
I then realize that nearly the entire internet states that it's not possible to fill this type of joint. That these boards are only meant for those who want joints in a grid pattern on the ceiling.
My despair is immense. Is it true? Is there anyone who can say something comforting or uplifting?
And do you have any rights when it comes to purchases made based on the salesman's explicit instructions?!

And do you have any rights at all when it comes to purchases made based on the seller's explicit instructions?!

Yes, that is grounds for a complaint, but the problem is proving what was said, and different stores can be picky about these things.

Which building supply store was it?
What you need is something like Norgips plan

But now they're already in place. Do you mean I have to tear down the whole ceiling and redo everything? Is that the only way?

 

[Emmazk]

Well, now they're sitting there. You mean I have to tear down the whole roof and redo everything? Is that the only way?

Yes, exactly. I'm mostly interested if someone can give me a success story with a trick on how you can still make it look okay nicely? Anyone? Please?

Can't you dig a bigger ditch?
Of course, it's not fun and it's likely to be quite dusty.

I had this issue in a house and then the painter used some filler called Ardex that was sanded down, then he applied Microlit (a thin fabric) which was then painted, resulting in a smooth ceiling.

Yes, you can fill the joints, glue a paper strip with non-woven glue or alternatively embed it with seam and joint filler. Once it has dried, spread generously and sand. Another option is to use microlith, which might be preferable in your case.

Even if you use regular gypsum, you need to chamfer and fill the short sides in the same way as your ceiling. But you don't need to tear down the gypsum. Gypsum as gypsum

Fill the chamfers and glue up the fiber cloth is probably the easiest.

A previous owner had filled in such things in our previous house, and it didn't crack while I lived there. So you can definitely have luck, but it's probably nothing to count on.

(All the joints were on studs, it probably would have worked worse in our current house where many joints are in open air.)

I put up such sheets and wallpapered a microlit canvas that was then painted.
Turned out really well!

It's possible, but you also need to create the right conditions. Minimize movements in the joint. The smaller the joint, the greater the risk of cracks. I would never install these panels on a material that moves a lot, such as träpanel. Then it's important to tape all the seams. Glasfiberväv could be a solution in your case as some have mentioned.

I have acquaintances who bought a house with such a roof. They have since plastered it smooth, about 20 years ago. It turned out well. I don't know if they have installed mikroliter. But mikrolit makes the painting have a finer surface. So it's good to use even if you have the right boards.
