screw hole and type of wall

[Plupp 154842]

Hi,

I have just bought a condominium and I basically have no clue, although I've managed to put some stuff on the wall, which was a miracle since I barely knew what wall plugs were, so I have a few questions.

1. What type of wall do I have? It's a house from the 1930s, the interior wall next to a neighbor. I initially thought it was a drywall because in several places the wall was hollow about 1-2 cm in, so I used molly bolts there and it worked well. In other places, it wasn't hollow but solid all the way in. It seems to be fine-grained white powder that comes out in both cases, and it worked well to use a screwdriver and "non-percussion drills," it must have been a drill for lightweight concrete

2. I was thinking of filling the leftover holes; there are quite a few holes from the previous owner that need to be filled too. I went to Clas Ohlson and checked both lightweight filler and some wall fix; in both cases, there were lots of hazard symbols. I'd prefer to go completely non-toxic, so I ordered this http://fargriket.com/butik/alla-produkter/fin-strukturspackel/. Is it as simple as mixing it a bit and then smearing it into the hole, wiping off to make it smooth, and letting it dry? I assume there will be less load-bearing strength in filled holes if I drill new holes and they happen to be in the same place, but maybe that's not a problem?

3. Probably completely unnecessary, but something I want to do, as long as there are no major disadvantages. I want to seal the holes that are used, i.e., put something in the hole and then attach the screw. Is there anything to keep in mind? I read that silicone releases fumes and shouldn't be used near outlets, etc., so I was thinking of latex?

A lot of questions, but hopefully, they can be answered
Thanks in advance

Hello,
It's hard to know exactly what kind of walls you have in your apartment from a distance. Often, it's a combination of materials, which in older houses have often been supplemented with new, modern materials.

The putty you have bought will likely work. Probably, you will need to apply/sand it a few times before it looks nice.
The load-bearing capacity where it is puttied will be reduced, just as you mentioned.

What do you mean by "sealing the holes"?
It becomes a bit difficult where you used an expansion plug/"Molly"...
Indoors, latex caulk/paint caulk is normally used (except in wet areas).

How far in have you drilled?

Hello, It's difficult to know exactly what kind of walls you have in your apartment remotely. Often it's a combination of materials, which in older houses often have new, modern materials added.

The putty you have bought will probably work. You'll probably need to putty/sand a few times before it looks nice. The bearing capacity where it is puttied will be worse, just as you mentioned.

How are you planning to "seal the holes"? It's a bit tricky where you've used expansion plugs/"Molly"... Indoors you normally use latex sealant/paint sealant (except in wetrooms).

I assume there are plugged holes in wetrooms that are sealed/silicone? Isn't it the same procedure for expansion plugs? Insert sealant and then the screw, Only 1 of 4 plugs expanded by the way since the wall wasn't hollow but they sit well anyway. The thought was to be as non-toxic as possible, latex seems okay, right? http://www.ekobyggportalen.se/byggmaterial/drev-och-fogmassa/ recommends cork paste whatever that is.

How far in have you drilled?

7-10cm in the new holes that I intend to try to seal. The old holes that need to be filled I don't know, but they have been for shelf mounts, TV mounts, etc., so some holes are wider.

In wet areas, silicone or other specially adapted sealant/sealing compound is used as mentioned.
Is that where you drilled?

No, living room
I'm a bit crawl paranoid, they have to get through the wall outlets if that's the case, not extra holes, probably non-existent, but it's for mental health

I usually use finspackel for screw holes, works excellently.

Thanks for the tips, the spackling went so-so but I'm satisfied since I've tried it now
I did half of the wall by wiping away excess with a damp cloth and the other half by trying to scrape it smooth. It felt like the cloth was the best, smoother better result.
