I have searched but not found a thread with a similar problem, so I'll create a new one. If there already is a thread about it, please direct me to it.
Now to the point.
I have cast a concrete wall with coarse concrete, used form plywood and it turned out straight. It looks pretty good but there are some bumps that weren't fully filled... Possibly because all the air wasn't removed. Not very deep, at most 1 cm deep, the worst has a diameter of about 4-5 cm, but most are about 1 cm in diameter. Anyway, I was thinking of filling these with something. Kind of like patching bumps/holes, but this is outdoors, so it should be something different but what? I was considering using expanding concrete or fine concrete + trowel. But are there other better ways? Don't be shy, feel free to suggest!

Could you not sift out the coarsest ballast from the coarse concrete you used, mix it up, and simply "spackle" the holes with your now self-made fine concrete? If you choose to use a different concrete, there is a risk it will have a different color, which is, of course, cosmetically undesirable.
Just a thought in the dead of night...

yes or fine-tune and steel-trowel it.
There will surely be loud laughter in the corridors but what does a stålglätta look like? It's not the first time I've come across that word but......
Now that I'm at it, I've been thinking of painting the wall so it doesn't matter if there are color differences. I plan to paint next year because I want the concrete to cure completely first. So now I'm wondering what type of paint you recommend? It's for outdoors, of course.

I don't laugh at least - if you don't know, you ask! There are many who think they know everything, but that's rarely the case...
I was thinking of googling an image of a stålbrätte (which is used for hand steel-glossing) and writing a few lines, but instead stumbled upon this page: http://www.dinbyggare.se/artiklar/artikel.asp?docid=411. Now I don't have to describe it

That link was good bygga_bo....
however, I wouldn't have waited 14 hours to scrub the surface.....
but now Binesch got to see what it was all about... You use a so-called "Stålbrätte".... however, I prefer another type, which is more pointed at one end.....

Thanks for the tip!
Now another thing, I've never worked with concrete before, so there's a risk I might ask newbie questions, but what is a concrete grinder like? I'm considering renting one to level everything out when it's done. Are they difficult to handle? How is the result? Coarse concrete contains pretty large aggregate, so how does the grinder work against that?

I have seen that link before. So I know what stålglätta looks like. But I meant how the surface working against the concrete looks? That's where I haven't been able to find any pictures. Otherwise, that type of tool looks conventional.
