Concrete walls in the kitchen, spackle or gypsum plaster before painting?

[Gammalthus18]

I've reached the end of this kitchen story. I have a ton of questions, but where I am now in the renovation, fixing walls is the easiest but also needs to be durable.

One wall was a pantry and there was an open frame around a fridge; where the fridge was will now be empty and it's just concrete there. Where the pantry was, a new one with the same dimensions will be installed, so not much prep work is needed.

There was wallpaper next to the fridge frame, which I've at least managed to remove. But how do you prepare the concrete and holes to be as smooth as possible before painting? Gypsum, putty, house fix, or what is most appropriate and relatively quickest and simplest?

If you're just filling small holes, I would choose Husfix, then sand and paint.
If you need to build up a few millimeters, I would use broad filler, then sand and paint.
For larger unevenness or transitions between different materials, I would apply 10mm of gypsum plaster with fiber mesh, then rub/smooth/finish and paint.

Good luck.

Hi, thanks for the response. It's hard to judge; the wall surface along the cabinet is fine except for an elongated groove and edges along the window next to it. I can attach a picture so you can see exactly where the pantry will stand where the white ends, so the rest needs to be painted white primarily, but groundwork is required as mentioned. There's a joint edge all the way, but it can be chipped away at least...
