How to finish the corner of a drywall?

[polarsson]

Hello

I am going to build a drywall that will end open in the room, meaning there should not be any door or arch or the like.

I plan to build with 70x45 studs and single drywall.
My question is how to finish the end of the wall. On the front and back sides of the wall, I thought of leaving the facade drywall panel, but what should I have on the end of the wall? I would prefer to use metal corner protection embedded in the outer corner.
Is it just a matter of cutting a drywall panel about 90 mm wide and plastering?

Thanks

Yep!
Then you attach the corner protectors and apply filler.
Alternatively, you can cover the corner with a corner molding if the rest of the room is molded. It is faster than filling and sanding and provides better protection against edge chipping.

No, I don't want a molding on the outside of the painting. It should be a metal strip that is filled in, sanded, and then painted.

Won't the metal strip protrude slightly? Shouldn't you then use beveled drywall on both sides of the corner so that the metal angle adds equally to both sides of the corner?

It is common to apply joint compound up to the corner of the metal. On the short side, you fill it completely, and on the long side, you apply a wider spread so that it doesn't show that it extends a few mm in the corner.

So actually, I could have beveled plasterboards on the long side, so I wouldn't have to do so much full-surface filling, plus I would get it completely straight?

Metal corners that you attach to plaster I usually go with. Fill the corners with plaster and drive in a few screws so the corners stay in place, then apply plaster so it fills up externally as well. When the plaster is almost dry, you can scrape off any bumps that protrude. Finish off with medium hand filler against the corner bends.

When something hits the corner, vacuum cleaner, etc., and paint gets worn off, just apply a bit of new paint. The plaster makes it so hard that there won't be any bumps.

So I could have beveled plasterboards on the long side so I don't need to do as much jointing and get it completely straight?

Exactly right!
If you can start with a new board in the corner, there will be less jointing

I use these, easy to install. Easy to plaster without showing after painting. If they haven't attached properly, which has happened sometimes, I've used wet room adhesive and stapled them in place. I removed the staples once the adhesive dried before plastering. It has worked perfectly.
