inside corner on drywall
I am going to install drywall on the walls and have never done it before.
I have bought standard 13 mm plasterboards with beveled edges.
In the four inside corners that form in a regular square room, how do you handle those?
I assume I can't have a beveled edge into a corner because it will be difficult to apply joint compound.
I also have arches between two rooms, and there will be some outer edges in the arch as well. How do you handle those?
I want corner protectors there but of course, I don't want any outlines to be visible showing that they are there.
I am also planning to paint directly on the drywall, so it must be perfect.

Cut the slices towards the inner corners to make the painter happy (or yourself when you need to spackle there).
On the outer corners, you should install special corner profiles, making the corners straight and hard, and spackle the profiles so they are not visible.!

set up the boards however you want
attach a paper strip
spackle
prime
apply sealant along the entire corner
finish with paint
For arches, not sure what's best. If not metal profile, probably also a paper strip there that you cut so it can bend.

Thanks for the response.
So what I understand is that I should try not to end with a facade edge anywhere? Inside corners as well as outside corners? Is that correct.
So if I finish the inside corners with straight edges against each other, should I then put tape there as well? Won't that show no matter how much I spackle because it will bulge out a little there?

We usually put cut edges against each other in the inner corners, then you just putty the screw heads and apply a latex sealant inside the corner... Right or wrong, I don't know, but that's what we always do and it turns out great.
I would also recommend two cut edges in the corners that you then slightly bevel, followed by latex caulk. Paper tape in the corners just creates more extra work because there will be a lot of filling and sanding before it looks good.
A tip can be to start plastering in the middle of the wall and set that sheet vertically, then you have something to measure against and it usually turns out tight and nice.
The question is how long it stays "great."Styx said:
It's NEVER wrong to use a paper tape in a joint.
In fact, I think you are wrong. A paper strip or fiberglass strip looks awful if it cracks in a corner. Latex caulk does not.
No, the boards must be cut at the corners. Otherwise, you have to spackle all the inner corners, and that's tedious, then you have to spackle all the inner corners again, and that's tedious, because then you have to sand, and that's also tedious, then after these unnecessary steps, you finally have to apply a latex. Three(!) unnecessary treatments in a corner! In a whole house, there are many corners to spackle.MathiasS said:
Okay.
I am a happy amateur who has listened to a recognized skilled painter. He said: Tape everywhere, even in the corners.
This has worked very well in my old wooden house so it's hardly completely crazy. No cracks anywhere.
Of course, everyone does as they please.

Well, in an old wooden house it probably works well, but I got the idea that ts was building new, which he wasn't. In new builds, you basically never do that.
Checked Norgips' website just now and they recommend using paper tape in inside corners, as suggested by others in the thread.
A bit strange, because the painters we use (various ones) are happy and satisfied with us cutting the corners as it reduces the amount of plastering needed.. I've also built three houses for myself using that method and have no cracks.
On the other hand, we always install an LP50 (smooth metal angle) behind OSB/plywood/gypsum in the inside corners to ensure there's no movement, maybe that's why cut corners work so well for us.

Neither I nor anyone I work with uses anything other than latex caulk in the inner corners.
In the outer corners, the beveled edge is maintained because the metal outside corner has a ridge that compensates for the board's beveling - the putty between the outer corner and the thick part of the gypsum provides a smooth surface.

Okay. There seem to be very divided opinions on this. It seems like I'm leaning towards doing as ACME suggests. Cut inner corners with latex sealant and beveled outer corners with metal strips.
But I have a question: Should you place the inner corners directly against each other and spray latex before bringing them together to get some in between, or should you leave a gap for this (how wide if so)?
I'm a bit torn. I've read in several other threads where most seem to say that paper tape is best and that if you wallpaper over latex, it will crack and become bubbly. Is this true? Is there perhaps someone who can share their experience that latex sealant has held up for several years? ACME, you seem to have done it many times. How many years has it held up for you?
We are planning to paint most walls but also have feature wallpaper on two of them.
By the way, where can you buy such metal corners?
