Repair "small" cracks in concrete wall

[HiScore]

Hello!

We have a neat crack in a wall made of concrete blocks. The crack is only about 5 mm wide, so it's a bit tricky to press concrete into it if we want to repair this crack. What could be used instead of regular concrete? Something that can be pressed into such a narrow crack. Would plaster work?

buy a product called lagningsmassa it should work. Otherwise, you can use regular husfix.

I would hack up the crack to a conical shape and then use plaster/mortar; if it is above ground, you can also use gypsum plaster.

Almost ridiculous that I didn't think of widening the crack a bit... Turned out great and it wasn't even that much work. Thanks for the help!
