Construction plywood or ceiling plasterboard first?

[Csms]

Given that you want to install 12mm construction plywood behind the drywall on the walls, should the ceiling be drywalled first, or should the plywood be mounted on the wall first?

Should the ceiling drywall rest against the plywood or should the plywood rest against the ceiling drywall?

It doesn't matter.

It doesn't really matter. However, I prefer to install wall panels first, as you have plenty of space to screw into the top rail.

I have seen both variants, including the version where the ceiling is plastered before the interior walls go up. Saves time for the carpenter but becomes trickier for the electrician...

Those 10-15mm above the floor where the OSB and drywall should end - is it above the finished flooring or above the (routed) chipboard flooring?

You can do it in different ways.

I first put OSB on the walls, then ceiling planks (Huntonit-type, mine were probably of the Tak-Ess brand) and finally I put wall gypsum. The wall gypsum last was necessary because I planned to have it without a ceiling molding and did not intend to plaster and paint a ceiling.

Mikael: do you have finished ceiling panels (like huntonit with MDF and "plastic" film over) and painted wall gypsum without ceiling molding? does it work?

csms: let the wall panels extend to the floor in the bathroom, otherwise it must be patched in the floor-wall angle

Mikael: do you have ready-made ceiling panels (like huntonit with MDF and "plastic" film over) and painted drywall without a ceiling molding? does it work?

We have wallpaper everywhere (except the kitchen).
A narrow painted snob rim at the top by the ceiling.

ok, can you upload a picture?

 

[Mikael_L]

What do you mean by the question "does it work?"

So I know what I should try to capture in the picture.

the transition between ceiling and wall without crown molding

 

[Mikael_L]

Do you want a picture with a cracked latex joint in the transition, or one that's intact?

The first one is really easy to fix. The second one I think I can also fix, if I search a bit I'll probably find a spot with a long enough section without cracks for a picture. :eek:

But I think I'll take photos tomorrow. Don't feel like it now, and it's starting to get a bit dusky, I think it will be better if I get a larger amount of natural light.

 

[nino]

crack or not doesn't matter

Hello. Now comes the next question. Are there any concerns aside from more cutting when installing 2400 plyfa on a 2500 ceiling height, thereby also getting horizontal seams (given that you avoid gneralslinga)? Will there be any other complications with the gypsum (which is 2500)?
