I have torn down a wall in the basement where it was framed with wooden studs and painted veneer boards on these (naughty-naughty with wood in a basement). Slightly mitigating, though, that it was an internal wall between two rooms, not an exterior wall facing the yard.
Behind were raw leca blocks. With some gaps in the joint and the blocks stagger quite a bit.
How can one get a smooth surface on these? What material? I have half a bag of house fix and half a bag of gypsum plaster, could that be something? What is the easiest to work with?
It is not living space but really utility space, an inconspicuous storage room in the basement that will be renovated (painted white) in the simplest way.
Thank you so much in advance!

It is usually advised against using gypsum plaster on basement walls. The most appropriate method is something along the lines of Finja's base coat A and then some type of plaster (B, C or whatever they are called). If you are sure that you have a dry wall, gypsum works.
The right way is indeed with base plaster, but I guess many skip it. I have applied it here in the basement; it goes quickly and is simple compared to the actual plastering job. However, I have skipped the reinforcement mesh.
It is fine to plaster with b-bruk or c-bruk. Make sure to dampen the wall a bit first to bind any dust.
Thank you for your advice!
Could the following be a candidate? http://www.bauhaus.se/rotband-20-kg.html
I'm thinking primarily because it seems easy to work with and versatile. It is vapor permeable according to the spec.
Can it be mixed by hand, or does it always need to be by machine?
And with or without mesh?

If it's a dry interior wall, plaster works fine. Brush the wall thoroughly first, and if it's very porous, you can spray a little water or primer mixed with water. The plaster you're looking at, I've used myself even on exterior walls (with primer behind) and then painted with silicate paint. It has stayed for over a year and nothing has come off. You don't need any mesh, but if it's a large area, it might be good to use plaster beacons to get it even. You can mix smaller amounts (max. half a bucket) by hand, but it can be heavy. It should have a consistency like porridge, a little looser than you might think. If you throw a small clump on the wall, it should stick without running down, then it's good...
