Hello,
We have strange walls at home that give me a lot of problems every time I want to attach something to the wall.
The walls consist of 50-year-old plaster that has now become completely porous; about 2-3 cm in are the concrete blocks that provide a good material to drill (plug) into. When you drill, the plaster falls out of the hole, leaving an entry hole much larger than the plug. It's almost enough to just look at it, and the plaster falls away. This means the plug can "wiggle." It might not be a problem for stability because I insert the plug deep enough to sit well in the concrete, BUT it doesn't feel right.
I borrowed some Ardex 828 to put in the holes, and it worked well, BUT it was a bit tricky to apply in a long, narrow hole.
QUESTION: Is there something similar to 828 or some filler that can be applied with a spray gun or something similar? Something that is easy to apply in holes, fast-drying, and provides a completely solid material (preferably drying to a white color)?
Or maybe there's a completely different way to do it?

If you want to be sure that it is secured properly, you can use ankarmassa. There are several different manufacturers, but here is a suggestion.

Going to build a kitchen wall and was at Krauta, they "tricked" 
me into buying something to inject into plaster if it's bad, they said, Fisher is the brand.
Is it really worth it?
I barely know if it's plaster or concrete wall behind.
Grateful for answers

What I'm primarily looking for is something that is easy to use and, of course, does a good job. If it's a bit "too" good, that's fine as well, compared to the other way around.
I noticed on the anchoring compound that it seemed practical to apply with a nozzle. How is its texture? Do you have to putty over it afterwards, or is it enough to just sand it and possibly paint? I assume it's okay to use indoors as well?
Thanks, Ola

Make sure to drill with a better drill to avoid making a large hole. Tape can help.
Drill deep and fill with assembly adhesive using a caulking gun or whatever you have at home (If it's not going to bear a lot of weight, it doesn't matter much). Insert a plug that fits the depth. Screw in the screw.
