ᐅ Drywall installation before plastering?

Hello everyone,

In two weeks, the plasterer will be coming, and right now I’m planning the tasks I want or need to complete beforehand. A major point for me is the drywall work. By that, I don’t mean the ceilings or walls, but rather:

• Cladding of internal downspouts in the garage
• Cladding of a wastewater pipe in a storage room
• Cladding of a service shaft in the living room

What do you think makes more sense: installing the cladding before or after plastering?
I’m torn. If I install it afterwards, the advantage is that the exterior walls maintain their airtightness. However, I’m concerned there might be a visible difference between the plastered wall (smooth, even) and the drywall surfaces. Is this concern justified?

Has anyone done this and maybe has photos of the finished result so I can see if there is a difference and, if so, how it looks?

Thanks for your help.

It definitely makes sense to install the drywall before plastering. There is certainly a noticeable visual difference when it is installed afterwards.

Yes, the walls will then be coated or re-coated. But everything has to be completely finished by that point. A friend had a problem when, after the drywall and plastering were done, he noticed that the flush-mounted toilet tanks were installed crookedly. He really had to do a lot of tearing out and reworking.
