I have searched the forum but haven't figured out how to attach OSB to a plastered brick wall indoors (not an exterior wall). Should I use mounting adhesive (PL600?) and plug and screw a bit here and there to secure it?
The reason is that I want to put OSB in the hallway, and half of the wall is behind a plastered chimney, the other half is a stud wall. So the first layer I want OSB, then I'll use gypsum.
The plan right now is to apply mounting adhesive generously on the plaster, then Hilti and plug the board with nail plugs so that the adhesive can work, i.e., I trust the adhesive to do the job.
Saw tips about tile adhesive, etc., but I have a lot of tubes of mounting adhesive that I need to get rid of, hopefully, they are equivalent.

pl400 sits as solid as a rock, no worries there... I would say it's enough to just screw it in place. Alligator plug and a few screws will do the job...
But I wonder why an osb, why not just drywall? Is it to get to the right level, then drywall is cheaper? It's no problem to attach things to a masonry wall, right?

Now it was in place, the last OSB of 110 pieces, phew. I had a lot of PL600 and it worked, there were plenty of plug holes from before in the wall, so I put in new plugs and screwed the OSB in place as well. (marked with a dab of glue and pressed the board, then drilled through for the screw). I glued the plaster to the OSB since the screws I had were a bit too long, but I did use some screws to apply pressure to the glue.
The reason for the OSB is that I have used it consistently behind all the walls, and only half the wall was plaster/masonry, the rest was framed. Now the OSB boards are finished and it feels good.
Now we just need to win tonight and the day will be complete.

Now I am in the same situation as pbengtsson was. The room has a dormer, 1m of the side wall has studs, and the rest is plastered and has old wallpaper. The side wall is an interior wall. Do I need to remove the old wallpaper before I attach OSB and then drywall?
The reason for using OSB is to have the drywall stable on the studded part as it will later be spackled and painted. Is a plastic film needed between the wall and the OSB board?
Is it okay to have a fiberboard between the drywall and the plastered wall, or is it perhaps entirely wrong given that it is an organic material that can absorb moisture?
For the exterior wall, it will be metal+roofing felt+sheathing+insulation+plastic film+OSB+drywall.

What you should focus on is securing the OSB to the plaster.
But I had brick behind the plaster (which allowed me to use plugs), what is behind yours? In older houses, it's sometimes plastered on ochre, reed, etc.
The important thing is to have fastening points for the OSB at about 30-40 intervals so that the board is pressed with the glue against the substrate.
