Problem! Crack in the entire wall behind the TV!

[Havsutsikt]

Regardless of whether you can fix it with filler and paint, it will likely crack again; a renovation plaster solves this problem. The wall holds, and it's more cosmetic that the crack is unsightly. If you have a crack indication, it often returns when the house moves.

Go with fiber-reinforced plaster. Then it won't crack.

Hm no you didn't misunderstand. Maybe I was thinking wrong :S But the wall is plastered, right? In that case, I thought the crack is in the plaster, the aerated concrete wall has moved which cracks the plaster on both sides but the stones are intact and held together with mortar and reinforcement.

I perceived the cracks as vertical, but the pictures actually show the crack both horizontally and vertically. If it cracked vertically as I thought, then the stones must have cracked all the way, which I considered unlikely. A horizontal crack, on the other hand, can follow the seam between 2 rows of stones and then, of course, the mortar can have cracked straight through the wall. :O

Okay, I'm a bit unsure what the term plastered means to be honest.
It is an aerated concrete wall that is spackled on one side so that it has become like a plaster (spackle) surface.
On the other side, the wall is not yet worked on, so there is still a raw aerated concrete surface for now.
The crack is vertical.

Regardless of whether you can fix it with spackle and paint, it will likely crack again, a renovation gypsum solves this problem. The wall holds, and it's more cosmetic that the crack is ugly. If you have an indication of a crack, it often returns when the house moves.

The crack is quite small, so you barely see it unless you look for it.
Moreover, it is an old house with concrete walls; all the craftsmen who have been here have noted that the walls probably won't move much anymore.

Use fiber-reinforced gypsum. Then it won't crack.

What is that?
I have bought a bag of ardex 828, do you think it will work?

The wall is plastered when it has been "clothed" with plaster, a layer of mortar that gives a smooth surface on brick walls. But maybe I'm completely off track here? Isn't the wall made of lightweight concrete blocks?
If the wall is cast in one piece, the reinforcement should hold the wall together even if the concrete has cracked. It is generally difficult to make cracks disappear by just filling them with putty; I would place a gypsum board if it was important to reliably hide the crack.

The wall is plastered when it has been "dressed" with plaster mortar, a layer of mortar that gives a smooth surface on masonry walls. But maybe I'm way off base here? Isn't the wall built of lightweight concrete blocks?
If the wall is cast in one piece, the reinforcement should hold the wall together even if the concrete has cracked. Generally, it's difficult to make cracks disappear by filling them with putty, I would install a drywall if it was important to securely hide the crack.

Well, I'm not sure if it's built or built. It's just a regular lightweight concrete wall. :|
Probably what you describe as cast in one piece.

I mean that you can treat the crack like a regular joint between 2 plasterboards. Recess a little and treat with fiberglass tape and plaster filler. It will not crack again.

The wall is probably made of aerated concrete blocks. They are in one piece from floor to ceiling and if I remember correctly 60 cm wide. A possible explanation could be that you drilled and plugged too close to the joint between the blocks. (Especially since the crack seems so straight). These walls are usually not plastered. It's not necessary, possibly just some filler in the joints. kamilenski's suggestion with through bolts and washers is very good,

I've learned that too d^_^b sorry TS if I complicated your life a bit :blushing:
How are the blocks attached to the floor/ceiling? with reinforcement or mortar or what? :S
Sounds likely that it's cracked between the blocks in that case.

Lifting the thread a bit.

I'm no longer worried about the existence of the wall.
One side of the crack I have reinforced with a strip and filled in connection with the whole wall being skim-coated; everything is in order there!

The other side, however, is in the living room and it's all finished there; I don't want to do anything advanced.
How can you find a smooth solution to conceal the crack so that it doesn't reappear?

Spoke with a painter who suggested using a thin layer of latex caulk and then "spot-painting" over it; how does that sound?

Exactly as it sounds, a bit of a shortcut, if you can't see it, it doesn't exist. The risk is that it will reappear.
