I have a basement room that needs fixing. Built with iso-leca blocks, 4 years old. Straight and fine walls. Two external walls and two internal walls. It’s a split level, so most of it is actually above ground. About 16 sqm floor area with a ceiling height of 210cm.
Regular plastering seems like a lot of work. It seems like you need at least 10mm thickness and have to work with guide rails, etc.
Is there a shortcut?
Can I “skim coat” with something like Casco's house fix or something else?
A few mm thickness should be enough, kind of like skim coating a textured wallpaper?
I was thinking of rolling the walls white afterward.
Initially considered gypsum plaster but maybe it's a bad idea if there’s a bit of moisture in a corner.

Heidis mortar plaster, works like gypsum but is cement-based and thus withstands moisture and breathes. Fully colored white from the start so you don't have to paint. Installed it in a basement 7 years ago and it still works well.
I recently plastered the walls in my basement, which I use as a woodworking shop, a somewhat simpler space. I used B-bruk and applied it as thinly as possible with a trowel and without smoothing. I mostly "smeared" the plaster on just to cover, but nothing more. After that, I used a broom, then painted it white, and I am satisfied with it.
My walls were not evenly built, with some remnants of mortar and concrete that had run down from when they poured the ceiling. This, together with the thin plaster and broom-textured surface, gave a nice result. A bit rough but with a lot of character.

Plastering as a beginner is not very easy, and it's heavy and dirty.
I plastered my extension on the inside. It turned out okay (workshop, so not too precise). Now I'm working on the outside, it's going great. It's fun to know that I've learned the technique and can now do neat plastering!

Now it's done. Did like "pjodden"
Used "putsbruk C hand" and applied a thin 2-3mm layer with a large plastic screed.
Then brushed with a wet broom to make it slightly striped, took about 8 hours for the entire room including the work on the outer corners by the door and window recesses.
Now it needs to dry for a few weeks before painting.
Also cut channels for electrical wiring first. Bought Jula's concrete slot cutter for 800 SEK, sliced like a knife through butter in the leca.

Don't remember the brand of the plaster. Putsbruk C-hand. I think I bought it at Hornbach but it’s available everywhere. Didn't use primer but vacuumed and brushed the walls first with a wet brush because they were dusty. Also chipped away all the mortar sticking out of the joints. Did the same in the garage a few years ago but then used a plastic leveling board instead of a brush for the “final finish.” This resulted in a smoother surface.G Greenoz said:
