Hello
First of all, I'm a complete noob in drywalling and this is my first project

I am building a drywall and have a 135 degree angle (please see the pictures). I'm planning to do two layers on each side of the wall. Could you please give me a few useful tips on how to do this ?
  • For example, should I do longitudinal or transverse planking ?
  • Should I fill the opening on the outside angle (the 225 degree angle)
  • Should I somehow prepare the drywall planks for this angle ? For instance cut them somehow special ?
  • Or do I just cut them as usual and fill everything with compound later ?

Thanks in advance

Do them as usual and fill with compound. Also, I would suggest adding an extra stud on either side of the angle for extra support, especially if you are double layering.
Hope this helps!

Stephen, thanks for the reply.
How do I go about the emptiness between the 2 studs (outside 225 degree angle). Do I need to fill that with anything ? Or just leave it empty ? (I read on somewhere that one should never leave such a "hole" in the angle, since this is a weak spot).
Also, in that angle, do I cut the drywall boards with a straight cut ? (90 degrees) or do I make a specific cut for the binding between the 2 boards ?

if you wanted to fill the space in, you could attempt to do that with a 2x4 but cut the angles on the sides of the 2x4. I would just use straight cuts for the drywall, and fill the space between them with hot mud. In general I'd like to use 20-minute mud, or durabond. Durabond would be suggested in this space. Then you can put on your off angle tape
