Repair wall after chasing

[gustavholm]

Hello, I've embedded a drain and electricity in plaster walls and I'm wondering what is best to use to even out the wall. Additionally, the holes between the rooms and in the floor. The wall with the drain needs to be extended by 1cm with plaster.

Ardex / plaster should do the job. I've used it for similar repairs and it has worked well.

Ardex / gypsum plaster should do the job. I've used it for similar repairs and it has worked well.

So, gypsum plaster in the tracks but in the floor and the big holes, would you have used gypsum plaster there as well? 👍

Is concrete filler the same thing?

Why not just regular plaster? Cheap and simple. Larger holes are repaired with concrete.

Can you link to something that would work? I found one but it said it only handles 1cm in layer thickness.

Webers/Combimix Gypsum or Gipsbruk works perfectly for filling similar holes. My experience is that it's a bit easier to work with than regular plaster mortar, even though it also works.

Gypsum costs 200-300 kr for a 25kg bag, and you can whisk it to the consistency of stiffly whipped cream that fills well and, most importantly, does not shrink.

Fill in with:

If you don't have super high requirements for the finish, the finbetong smoothed at the end is enough.

If you're not expecting a perfect finish, finbetong alone smoothed at the end will suffice.

Can you use finbetong on the floor as well?

talked to the carpenter about the wall and most have said plaster mortar. But there are both A, B, and C, which one should be used? It's a basement wall that is below ground.

Can this work otherwise?

Do you have to prime the wall before using plaster or can you just mix and apply it? 👍
