Filling holes in a concrete wall

[Saaben16]

Hello!
I have a large hole in a concrete/brick wall where there used to be an electrical box. The hole is about 9cm deep at its deepest point, what can be used to fill it?

Buy some regular Putsbruk C and throw it in.

Can you fill such a deep hole in one go?

Hard to see how deep it is, you can do it in a couple of rounds if it's many cm. You can also press in a piece of brick or even a gråsten.

I usually use plaster/gypsum plaster (same thing). Easier to work with and hand sandable. If it's not for an exposed environment.

Insert something more fun than a stone, but form-stable, and plaster it in.

Put in something more fun than a stone, but dimensionally stable, and plaster it in.

Maybe a part of a colored glass block with LED lights, could be charming 🙂
