Repairing/building a wall/corner

[Danken88]

Hi! I am new both to this forum and to building/renovating at home.

I have taken down a smaller wall and need to create a neat "corner." The wall is built with "blocks," which I believe are aerated concrete.

Some of these blocks came loose during the demolition process, which now means I have 2 "voids" to fill before I can plaster, set the corner profile, etc.

Is it best to buy repair mortar and "fill in" or to buy aerated concrete blocks and cut them to size, together with repair mortar? Or is there another recommended approach?

I have no experience with either concrete blocks or cement/repair mortar, etc., so tips on products are also welcome.

Grateful for any advice!

Double-checked that it wasn't load-bearing?

I would have used mortar/filler and tried to fix it

Linking to a concrete filler that is extremely easy to work with for beginners, quite expensive but easy to get it even and nice, plastering is difficult if you're not skilled at it, takes time to get it right.

Some of these blocks came loose during the demolition process, which now means I have 2 "voids" to fill before I can spackle, apply an edge profile, etc.

Is it best to buy repair mortar and "fill in" or to buy aerated concrete blocks and cut to fit, along with repair mortar? Or is there another recommended approach?

I would not use concrete spackling but use low alkali mortar like, for example, Putsbruk C..
Alternatively, gypsum mortar..

Hello, thanks for the quick responses & great tips.

No, the wall was not load-bearing (Which I obviously checked beforehand).

Is the volume/surface not too large for mortar/filler? We're still talking about 20 (Height) x 7 (width) x 10 (Depth) cm at the largest spot? Or is it just a matter of doing it in rounds?

Isn't the volume/area too large for mortar/filler? We're talking about 20 (Height) x 7 (Width) x 10 (Depth) cm at the largest spot? Or is it just a matter of going in stages?

Yes, for holes that large, it's better to seal them with lightweight concrete blocks.

The wall/corner is now fixed with (for me) good results.

Used plaster mix and some pieces of lightweight concrete blocks from the demolition.

Thanks for the tips & help!
