Renovate pantry

[Hammarfall]

Hello!

I've been a homeowner of a 1930s villa for five weeks now. I'm completely new and have moved to a new city and don't have many people to ask.

The pantry was lined with plastic sheeting directly against the inner wall, followed by insulation, wooden studs, insulation, and an old wood panel. I could have repainted the wood panel and ignored potential problems but chose to tear everything down instead. This is how it looked after I demolished it.


On one side, the wooden studs were rotten, otherwise, it looked pretty good. I've chipped away all the plaster that was loose. Now I have two questions for you: Can you see what material is behind the plaster, what I'm calling concrete?
I would like white walls, either silicate or limewash paint. Can I paint this directly on without plastering? Does plastering have any other value than appearance? The reason I don't want to plaster is that I don't think I can do a good job myself, and I think it could be expensive to hire a mason.

It looks like lightweight concrete.

Of course, you can plaster this yourself. Watch some YouTube videos beforehand if you're unsure. Plastering a pantry is a perfect DIY project.

In the pictures, it doesn't look that large? Hiring a craftsman for this probably won't cost many thousands. It's a job that doesn't take much time.

Sure, you can paint directly on the concrete, but it doesn't look as nice (in my opinion).

It looks like it's lightweight concrete, I agree. I have now scraped off most of the plaster. About 1/3 came off with a light touch, 1/3 quite easily, and 1/3 is quite hard to remove.

The wall surface measures about 16m2. I would like to see examples of how painted lightweight concrete looks, without plaster. I'm having difficulty googling it. Otherwise, I like the contours that can be seen in, for example, tunnels.
