Tips for plasterboarding a ceiling

[mikmal]

Hello

I'm planning to install drywall on our bathroom ceiling. The ceiling needs to be completely smooth (i.e., without seams, according to the design chief (my wife...)). The room is about 3.70 x 3.90 m. The panels are 90 x 244 and will need to be joined, of course. I've installed furring strips (28x70) with a 30 cm gap. My questions are:

1. Do I need to install short pieces (about 23 cm) between the furring strips where the panels are joined and at the walls?
2. Should I stagger the seams on the ceiling or can I go with straight seams? What is best (which will crack the least, be least visible when done with spackling...)?

I had set 23 cm kortlingar, then generalskarvat, but at that point, I expect pushback.

Counteraction was desired. Counteraction was given. I would have preferred to offset and if you want it really stable, then send up two layers.

You can attach the short pieces once you've set up the first board. Screw them in at the edge while holding the short piece with your other hand. This way, you save time and the job becomes easier. One layer of plaster is sufficient.

actually no short pieces are needed.
you never lay short pieces when drywalling under the ceiling *short plank etc.*
unless you just want to and feel like it!

no general seam, stagger the seam instead.!

Agree with everything estwing has written.

Do this properly now, not on piecework, it's such a small roof, so it won't be much extra work..

I had put in the kortbitarna.

Okay, I guess it'll have to be like this then ...

Blocking against walls and at joints, as well as staggered joints between the panels ...

One more question then: Did you cut away the recess on the first panel (so it becomes 60 instead of 90) to avoid having to spackle the entire length and only spackle the screw heads (no ceiling moldings are ordered from the designer ...)

Recess that does not go against another recess, such as at a corner, or break between wall and ceiling, I usually cut away, otherwise there tends to be a lot of complaints from the painter. If the framework allows, I just cut away 5 cm in that situation.

 

[error_elle]

I would have also cut away the recess

Sounds good, remove the plaster joints towards the walls so you make it easier for yourself, much easier to plaster.
Also, if your bathroom is on the ground floor of a two-story house, I think you should consider a second layer of gypsum with staggered joints. It should be a smooth ceiling, hopefully without future cracks... then it might be worth screwing two layers.
Good luck!
