Paint basement walls or plaster them? How would you do it?

Hello,

we want to renovate the walls in the basement.

As you can see in the picture, there are still some youthful mistakes ;)



They were previously painted with normal dispersion paint and partially sprayed with spray cans.

We want to have the walls newly painted in white now.

Last year we had an expert in the basement who measured everything for moisture. Everything is within the normal range.
There are few efflorescences on some walls. The wall in the photo is the one facing the neighbor. It is built with such white stones. There are no efflorescences there.
The other walls border the outside and are plastered.

Regarding the plastered walls, the expert said we should apply mineral lime plaster and not paint. This would reduce the efflorescences because the wall could "breathe" better.

Now I'm considering whether I should simply cover all the walls with lime plaster.

Do you think the lime plaster will hold on this painted wall in the photo?

Thanks & regards
Peter
