Old basement wall with insulation?

[cubix]

Even for larger damages /erosions?

Absolutely! For larger cavities, gypsum plaster is preferable to lime plaster!

Not gypsum plaster as it expands when it comes into contact with moisture.

If one suspects they have damp walls then. What should one use instead?

If you are going to plaster where there is a risk of moisture, do not use gipsputs.

If you are going to replaster a wall, it's best to use the same type as before. Putsbruk b or c or kc.

I have plastered basement walls myself with putsbruk c. I find it difficult to get the perfect mix, but when you succeed, it's easy to plaster. I plastered deep holes twice.

I have plastered interior walls in a completely dry space with gipsputs and it's more forgiving on how you mix.

It gets really dirty when I've plastered. Once I had help from a mason when we replastered an entire garage and it didn't get nearly as messy around...

My walls are dry now anyway. (Should be) But when I'm doing this hellish job, I just want to do it once and not risk having to redo it because I used the wrong plaster/material.

Are they exterior walls in the basement or interior walls in the basement with an uninsulated basement floor, then I would not choose drywall.

Instead, I would choose traditional plaster...

It's not a job you want to redo unnecessarily...

Ok. That's how it will be. I have a mason on G to look at it. I have many projects here at the same time and need to buy myself some time. But if it gets delayed or too expensive, then I'll have to do it myself. Grateful for your answers.
