Paper tape between wall and ceiling?

[Smeafan]

Hello!

I have plastered walls and ceilings and don't plan to use any ceiling moldings.
Should one use a paper tape on the joint between the wall and ceiling or should it be done in another way?

Regards

Do you also recommend it in the inner corners of the walls?

Yes

 

[Smeafan]

Yes, it would have been nice to avoid putting a strip and spackling there.
No risk of it cracking?

 

[Smeafan]

Or rather, is there a greater risk of cracks if you do so?
You can never be completely sure.
There will be wallpaper on the walls, if that makes any difference.

If the house/corners aren't too shabbily built, sealant is enough. Sika's acrylic sealant has 15-20% elasticity.
