Primer or slurry basement wall

[platon1980]

I have torn down tiles and left a dusty and somewhat sandy surface, this works fine to apply primer on, it becomes firm and good, but I'm afraid that the primer will block moisture migration in the wall (outer wall, old drainage). Do you think slamma works just as well?

I bought Bostik P6000 instead of the acrylic-based Probau that I had at home. Apparently, Weber has one that is claimed to be diffusion-open, but if slamma works just as well, it's simpler and cheaper.

What are you going to put on the wall? It's crucial...
Primer breathes for that matter, so it's no problem.

Häpp. a bit unclear, tiles are going up on the wall

I definitely had primat. It is such a small cost that it is almost silly not to do it.
