Are they doing it right?

[Plupp 56656]

I have a lightweight concrete house.

Renovating the living room. The walls are being plastered with Weber Gypsum plaster. Then it will be painted with a silicate paint.

The craftsmen seem to be applying a layer of about 2-5 mm of plaster. Seems reasonable.

However, in the (inner) corners, I can't see that they've reinforced in any way. I've seen these "reinforced" tape strips. But they haven't used those or anything else.

Are they doing it right?

Isn't there a risk of a crack forming in the (inner) corners after a while? The plaster dries, the house shifts a little.

My experience with craftsmen after ten years with a house is that 9/10 craftsmen take the easiest route. Sad. But that's my experience.

If the house moves (which generally only happens with ground settlements in stone houses) to the extent that the plaster cracks, the crack will occur whether you have reinforcement or not. Since your house seems to have been standing for a while, the risk of movement is probably very, very small.

According to Weber's website, they do not recommend any type of reinforcement in inner corners. However, they recommend an outer corner profile to help achieve a straight outer corner. Save some of the silicate paint so you can apply some new if it cracks, or save the paint code and brand so you can buy new if you need to touch up in the future.

Here is a link to Weber's product page on gypsum for indoor plastering.

Thanks for the reply. No. I haven't found anything either. So it seems to be okay.
