Hello!
We are planning to turn a room in the basement into a hobby room. We have gotten as far as removing all the wood + studs that were on the walls so that the concrete is exposed. In some places, it is bare concrete, there's also an area that's been blocked off with lecablock, and in other places, there is still plaster and paint. It's even painted with a moisture barrier in one spot in the middle of the wall for some reason. Two walls are exterior walls and two are interior walls. So, to my questions.
What do you recommend doing? Apply new plaster where there is none and then paint over it? Frame with steel studs and install drywall on them and then paint?
In some places, we need to repair large holes, what is recommended to use? If I understand correctly, there are some types of mortar that don't work with certain concrete, how do I know what fits? I don’t know what’s currently there, is there a way to find out?
Which drywall or paint is recommended for basements?
Also, the concrete floor needs repainting, what paint is recommended for floors?

No, there has been no previous moisture problem. No high levels were recorded during the inspection 2 years ago, but the inspector recommended that we remove the panels on the wall as they were mounted with wooden battens. They were dry by the way, and there are no cracks in the concrete, no bad smell either. However, some of the plaster has come off along the bottom near the floor. The house was drained in the 80s, but I cannot say with what (it was built in 1963). No high moisture levels have been recorded elsewhere in the basement either.
Yes, it depends a bit on what your requirements are for surface layers in the "basement," but there are a few different options, such as:
1. Plaster the walls and paint with a suitable "breathable" paint, like silicate paint. See some info here:

2. Frame the walls again with metal studs and put drywall on this. However, remember NOT to insulate the wall/no plastic on the part that is below ground level. For completely dry interior walls, you can also consider "gluing" the drywall to it:

Adding to this thread a bit.. I know there's been talk a hundred times about walls in basements..
If you have 10cm of foam insulation on the outside and want to insulate on the inside... can't you just do an air gap, plastic, insulation, drywall on the inside??

Okay, but if we choose to plaster the wall, what do you say about these questions?
"At certain places, we need to repair large holes, what is recommended to use? If I understand correctly, there are certain mortars that don't match with certain concrete, how do I know what fits? I don't know what is there today, is there a way to find out?"

I have dry basement walls and have used plaster in some areas that is easy to use. More of a filler type than regular plaster.
But here several might need to comment since there are some different opinions, but I assume dry walls.

I haven't heard of needing to be cautious about combinations of concrete-mortar.Kansas said:Okay but if we choose to plaster the wall, what do you say about these questions?

I would fill the holes with concrete and then plaster the last cm.
Personally, I have removed all the plaster/paint in the room I am renovating, then refinished the wall. However, I didn't find the surface smooth enough, so I have skim-coated it with adhesive for tiles. Significantly nicer to smooth out with than plaster according to my experience. However, I know others have managed very well with just plaster. I would completely avoid gypsum products, even if it's dry and fine now, you never know in the future and I wouldn't want to remove it. An alternative I've considered is that one should be able to install fiber cement boards or something similar directly without an air gap, but I haven't seen anyone do it. Can someone explain why this isn't done?
