Tongue and groove board behind drywall, how to handle the corners?

[spaxx]

Hello,

I will now start installing 23mm raw edge board on all indoor walls, then a layer of drywall on top of that.

I'm wondering what is the best approach for the corners, should I attach a "metal corner bead" in all inner corners before screwing on the drywall? Because the raw edge board might move slightly, potentially causing the drywall corners to crack?

I have 17 mm råspont, that should be enough if you place it in the corners where one side is an outer wall, place it under the plasterboard, otherwise it will come too far in.

Hi,
I don't quite understand what you mean by it coming too far in. When I have a corner where the råspont meets, I'm considering installing such a metal corner that I screw into the råspont.

Hi,
I don't quite understand what you mean by it's coming too far in. When I have a corner where the råspont meets, I consider mounting such a metal corner that I screw into the råspont.

But nothing has happened in those corners either. I put paper tape and filled in the corners then.

I happened to place some metal corners before I installed the råspont, then the drywall screws didn't reach the metal corners when I placed the drywall afterward.

"Metal edges," you typically have those on exterior corners to protect the delicate drywall edges?

I think they mean one of these

Hello,
These are the ones I'm thinking of, but there might be alternatives:

Yes, those are the ones I've used. For outer corners, I've used a paper strip with a metal strip on each side of the middle.

exactly works on outer and inner edges inside the gypsum

 

[Snailman]

That's what I've used, yes. For outer corners, I've used a paper strip with a metal band on each side of the middle

I use the latter instead of a paper strip in outer corners on top of the plasterboard.

I use the latter instead of paper strips on outer corners outside the plaster.

Different, cool that it works for you. How do you attach it?

 

[Snailman]

different, fun that it works for you. how do you attach it?

I embed it like with a regular paper tape, but it can handle a bit more than the paper tape due to the plates

I have gypsum in all window and door recesses, so this tape was cheaper than the punched metal profiles

I plaster it in like with ordinary paper tape, but it withstands a bit more than the paper tape due to the plates

I have plaster in all window and door frames, so it was cheaper with this tape than the punched metal profiles

aha. thought you took sheet metal angle and set it. no those punched metal profiles are not fun.
don't you like those in "plastic"? https://www.k-rauta.se/byggvaruhus/självhäftande-hörnskydd-l-2500mm

Checked them out at biltema http://www.biltema.se/sv/Bygg/Kakel-och-mura/Tillbehor/Hornskydd-for-gipsvagg-2000022631/

Didn't notice the equivalent at krauta, then I overbought the strip. I think it was on sale or something, have used it for 13 windows and doors plus some other external corners. I also have about 30 more windows and doors in another house to fix later, which the strips will probably cover as well.
