Choice of materials for basement wall

[Ernfrid]

Hello!

I am going to demolish the recreation room. I am thinking of plastering the walls in the basement, which plaster withstands moisture the best? Would regular Putsbruk C work?

Would it be possible to order white-colored plaster, then you wouldn't have to paint, right? Or would it be cheaper with silicate paint over it?

I don't want it to peel off after a year, or are there other alternatives?

If you have moisture in the wall, you should start with that problem, not the effect of it.

You don't use white colored plaster, it's silicate that applies.

Yes, it definitely smells like a basement, I guess there's mold in the insulation, so I would like to get rid of the entire den as soon as possible.

I could start with demolition, removing the wooden floor and everything else. Then I can leave the walls bare until I know if the walls are dry enough and if drainage needs to be redone. I don't know what it looks like back there right now. I'll just leave the wall bare, it might already be plastered, no idea.

But there will always be moisture from the slab, so at least the lower part of the wall will more or less be affected by moisture.

Under the wooden floor, there's sand and a roughly torn slab. Can one pour over the existing slab to make the floor smoother? I was thinking of laying needle-punched carpet over it afterward, I think tiles would be too cold.

Yes, start tearing down and see how it looks. I personally get chills from framed basements, so you're thinking correctly here.

 

[Ernfrid]

Same here regarding the uppreglad basement, just want to get rid of it as soon as possible.

Needle felt should work to lay directly on the slab, right? How uneven can it be? Otherwise, it's self-leveling compound that's needed. If there are individual large holes, you can fill them with fine concrete.

I don't know how smooth it is, but reportedly it should be "roughly scratched," so I hope it's smooth enough for the carpet.

Well, a rough concrete surface usually means that it is so coarse that you don't slip on it when wet. It is probably also even, but as you say, you won't know until you see it.
