Hello,
I need some plastering tips on the following questions:
1, I've made a hole in the ceiling for the stairs to the upper floor, where there have been some larger cracks/holes about 5 cm in the ceiling plasterboard. How do I patch it up? Do I cut away and put a new piece with a paper strip at the seam? Or can I just plaster it?
2, around the window reveal, I have a plasterboard wall, the gaps that are against the reveal, do I plaster or caulk? Caulk, right? If it's a bit larger gap, should I plaster first or is there a risk of cracking?
3, seam slanted ceiling and ceiling. I'm planning to go without ceiling moldings and have neat joints instead. How do I do this the best without cracks? The boards are up but not cut at an angle, so it needs to be plastered out to create a good angle. I was thinking of plastering out first to get a neat angle. Then gluing a paper strip to avoid cracks and after that plastering again, is that okay? Or should I caulk under the paper strip before gluing it?

There are a few different options for filling larger holes. I bought "gypsum filler" I believe it was called, a product from Casco, which I purchased at K-rauta. It worked very well. However, I found that you should mix in a little less water than what was stated on the package. It was a bit too "runny". It's the right type of product for your cases 1 and 3.
I know there are several other types of gypsum spackle.
The one I mentioned above becomes very hard, so you should make sure to have a little less rather than too much in the holes, and then fill with regular spackle and sand. In case 2, you usually have moldings, window casings that overlap. Otherwise, you should probably use sealant there.
