inside corner on drywall

[Mikael_L]

Hey... I start by placing a metal bracket first against the outer wall corners and other corners facing the outer walls. I also have lying 45x45 on the inside of the outer walls. Then I first place OSB against the metal bracket and finish with gypsum. And I cut, chamfer, and seal exactly as Acme suggests.

oh, do you also put metal brackets in the inner corners of interior walls?

I have already mounted tongue and groove boards on one side of two interior walls facing the exterior wall and probably won't take them down to fit a bracket inside the tongue and groove...

It is sufficient to place the metal angle inside the last layer of drywall.

What about inner corners in the bathroom when installing a waterproof membrane on the drywall? Filler + paper tape or flexible sealant?

It's enough that you place the metal bracket inside the last layer of drywall.

It should do, - possibly even be better, I'm not quite sure.

I started with the metal bracket because it keeps control of the electrical conduit running through the corner and helps to secure the insulation.

But YES. I put a metal bracket on all corners facing the exterior wall, otherwise the board lacks support in the corner with cc600.

I understand that there is a greater risk where inner walls meet outer walls, but is it not considered necessary to have a metal angle in inner corners where inner walls meet inner walls? Maybe it can be read between the lines in the thread...

oh right, the drywall, the first sheet, you let it go all the way into the corner and then butt it against it with the sheet from the other side of the corner?

I only set angles against exterior walls.
The reason is that in the corner, there is no support for the OSB and drywall except exactly where a horizontal 45 is located (the cross-braced framework).
If I ignore this and then place a fixture near the inner corner at an exterior wall, the wallpaper or paint is likely to crack as the board buckles between the horizontal 45x45s.

If I disregard this and then place a bracket near the inner corner by an outer wall, the wallpaper or paint is likely to crack as the board bends in between the horizontal 45x45s.

ok, the raw board is probably a bit sturdier than OSB I suppose, so I hadn't thought about that, but then I should also be able to settle for metal angles against the outer walls, I think...

 

[Mikael_L]

Yes, I don't place any metal angle anywhere in the inner wall against the inner wall, there are already standing studs on "both sides" that provide proper support for the plasterboard. Yes, there is a metal corner guard on an outer corner, but that's installed after the plasterboard.

Where can you buy cheap metal angles? (LP 50) They aren't available at Byggmax

 

[Mikael_L]

That should do it, - maybe even improve it, I'm not quite sure.

I started with the metal angle because it keeps the conduit stable as it goes through the corner and helps to secure the insulation.

But YES. I place a metal angle against all corners facing the exterior wall, otherwise the board lacks support in the corner with cc600.

I should find the original pictures and upload not quite as compressed images.

At that time, I recall the forum had a limit on how many MB you could add with pictures.

Thanks! Nice with some help like this 10 years later

Do you need such an angle iron in inner corners if you are going to install both OSB and plasterboard?

 

[Styx]

Yes.
Especially if you have installation compartments without standing support in the corners.
