Seal holes after ventilation pipe, aerated concrete.

[AlfaHannes]

Hello!
I have a 100mm hole after moving some ventilation pipes (see image).

The wall is made of lightweight concrete. Obviously, I will need to fill and repaint after I fix the hole, but what is the best way to cover the hole?

Leca balls mixed with plaster is an option I would consider when you're going to putty and paint anyway.

Is the exterior brick?

Lecakulor mixed with plaster is an option I would consider when you are already going to putty and paint.

Is the outside brickwork?

The outside is the inside of another room, it's an interior wall about 90mm. I'll check out leca+plaster, sounds pretty convenient!

When it is inside on both sides, a lid of plaster from both sides works as well, and some rules in the middle that you attach to the wall.

Concrete blocks and a little plaster mix. It's cheap and good without complications

Foam and putty from both sides
