How to spruce up a shabby basement wall

[Hejkomåhjälpmig]

Hello!

Regarding the project to straighten a slanted basement wall.

I want to install some form of sheet material, wet room drywall (?), and then paint it. It should align with the floor heating cabinet that protrudes about 4-5 cm.

The wall itself is wavy, with differences of probably 5-6 cm in some places between the highest and lowest points. It's built from a mix of poured concrete, lecablocks, gypsum blocks, and old "hollow concrete blocks."

Any tips for framing it up?
Some form of adjustable steel stud?
Should I plaster the wall beforehand?

Level with a steel rule and adjustable spacers behind so they get the required support.

Then plasterboard on the studs.

Then drywall on the studs

I have never worked with steel studs before. Is cc60 sufficient? Tips on what type of spacers are suitable are appreciated.

Moisture-resistant drywall? During the summer months, it's >70% RH in this space.

Depends, if the wall is purely cosmetic, it should be sufficient.

Regarding the type of spacers, I'm not sure what they're called, and I can't find them when I google, but otherwise, you can use two wedges inserted from both sides (overlapping) behind the metal stud until they cover the gap behind it.

I believe the only real difference between "standard" drywall and moisture-resistant drywall is the surface layer (the gypsum itself is the same = inorganic).

Steel studs work well, but you might want to use some type of minerit/cemberit board instead that is not moisture-sensitive...
