Hello,

I had the wall plastered with fine plaster c. Shouldn't it have a smoother finish? It's a 0-1mm grain. Additionally, the transitions (the darker spots) in several places don't feel quite right. When you run your hand over them, the plaster (the grains) loosen, and it's not as hard as the rest of the surface. And the vertical lines in the corner don't feel very professional either. Does anyone have experience with this?
 
  • Wall with uneven fine plaster finish, visible texture variations, and vertical lines, highlighting issues with plaster adhesion and smoothness.
  • Plastered wall with uneven surface and color variations; features rough texture and visible vertical lines at the corner.
  • Plastered wall with uneven texture, visible vertical lines in the corner, and color variations, indicating issues with finishing and adhesion.
  • Texture of a wall after fine plastering with visible imperfections and uneven surface transitions, highlighting some darker areas and vertical lines.
  • Uneven plastered wall surface with visible texture and rough patches; some areas appear darker with a slightly cracked texture.
  • Plastered wall with uneven texture and dark vertical lines in the corner, showing rough transitions and loose grains on the surface.

No, it doesn't look okay. I don't understand how they managed to get all the scratches and marks in the plaster. What kind of surface treatment are you planning to have afterward?

Hmm, can one repair sporadically, or does everything need to be replastered?

I was just planning to paint, or what other options are there?

That was probably a bit of a silly question from my side considering your post. You could wallpaper or frame the wall and put up plasterboard, but then your question wouldn't be as relevant :).
I'm no expert on what can be done. Repairing seems doubtful, possibly applying a new thin layer of plaster.

Plastering is tricky, some people want a rougher surface and others don't like it. Did you have any discussion with the craftsmen beforehand?

I had craftsmen at home who plastered two walls in a room in the basement last fall. The walls had a layer of blåbetong that I had torn off. But the walls themselves were not straight at all (house from 1908) so we agreed that they would be plastered freehand. So they are a bit wavy but the surface is definitely much smoother than yours.

No, not specifically about the texture. But I assumed they would be smoother automatically when it was fine plastering. I almost thought the coarse plaster was smoother.
Should one be worried about the transitions, the darker sections, do you think? That they are loose grains and a slightly different texture, or is that normal?

I don't think you need to worry about that. The appearance will be a bit different once you've painted and depending on the lighting. However, you need to decide beforehand because you don't want to paint first and then realize you want to add another layer of plaster.

This is what my wall looks like. Plastered in November and just painted with silicate paint. A white plastered wall recently painted with silicate paint, featuring a small, arched window. Plastered wall and window frame, freshly painted with silicate paint.

Thanks for the pictures.
Maybe it's the paint that does it? but it looks like you have a much finer texture and no larger "scratches"?

It can happen when a too thin layer of brukskickt has been applied. Nothing strange in itself, looks like a scrubbed wall, probably tastes like one too.
You can't fix it in the cracks, you'll have to apply another layer.

If it is to be smooth, the surface needs to be finished with a steel trowel just when the compound has stiffened but not hardened. Additionally, the trowel should be somewhat slightly convex so as not to snag but glide over the surface. Many bought from building stores today are just a flat piece of steel.
But that would probably work quite well if you paint. There is a bit of life in the surface.

The different dark areas won't be visible once you've painted.
The scratches should have been taken care of when you polished. Now I would have mixed some of your paint with sand and painted over the scratches so the sand sticks in the scratches.

Hmm. If the darker part is a bit loose, maybe it can be brushed away with a fine brush or with your hand?
 
can just sand off the worst and then just paint

Had a wall that looked similar to yours after the plastering. I applied a layer of sand paint at the base to even out and "calm" some of the texture. The result turned out great in my opinion.
