Hello everyone.
I have mounted Elfa brackets on a plastered brick wall using regular Gunnebo plastic plugs. I loaded the shelf a bit too much, so the plugs have worked their way outwards and left significantly larger holes.
There are three solutions as I see it.
1) Fill in with matchsticks and use a larger screw (bad solution).
2) Drill with a larger dimension. Use a larger plug and larger screw (a bit better).
3) Blow out the hole, use cement-based filler and a new plug. (recommended solution according to experts if you want it to last long, see link below)
The question is: What is "cement-based filler"?
Regular wall filler?
Where can you buy it? Claes Ohlsson, Jula, etc?
Does silicone or construction adhesive work just as well?
Link with instructions:

Thanks!

no, regular filler is not the same thing
recommend a larger hardware store (though smaller packages might be available at places like jula, clas ohlson, etc.)
not silicone, maybe could work with k.lim.
"expert" in the picture seems to use something from danalim.
personally, I would go for threaded rod and injection compound
since it seems to be heavy stuff on the shelves

Thank you!
What I find at the stores I usually visit is: http://www.bauhaus.se/betongspackel.html
But it's like mixing cement. Even the link you gave me is like that. How do you get it deep into a hole?
Can you fill an old caulking gun? Or is there another trick?
Or is it available pre-filled in a gun?
If so, does anyone know where you can buy it in the Stockholm area? I usually just go to the big stores.
Thanks again!

I would recommend anchor adhesive and threaded rod. Anchor adhesive is sold at all major hardware stores and usually comes in a cartridge.
Fischer and Essve have good images on how to use anchor adhesive on their respective websites.
Good luck!

Fisher has a product called Cement express, available at byggmax.yakumo said:

Chemical anchors are the thing. http://www.beijerbygg.se/store/privat/fästdon/infästning---expander/kemankare-ingjutning
is available at Biltema, I think they called it anchor mass, holds like a rock in my leca walls

Isn't it easier to use the right plug for the hole? In brick, it usually holds really well. Or am I missing something?
. Most holes end up in the brick, but in my current project, unfortunately, a few will be in the mortar between the stones...Deep holes at least 10 cm, 2 plugs in a row in the hole + long screw
In poor plaster, anchor compound and threaded rod work very well.
Available at most hardware stores, byggmax, biltema, and (I think) Jula.
It should be possible to use anchor compound and certain types of plugs and regular screws, but I'm not sure about which ones to use.

Thanks Liteavvarje and hempularen for the tips. Threaded rod was not relevant for my application, and I didn't really feel like messing around with mixed compounds or two-component solutions. Here's what I did when I ended up with the hole in "loose" mortar:
First, I vacuumed away everything loose and then pressed in "just enough" (=quite a lot) of Fischer cement express, after which I created a hole in the soft mass, first with a pointed 6 mm rod and then with an 8 mm rod. When the 8 mm rod was in place, I applied mass from the outside and sort of vibrated it in around the rod. The rod could then be twisted out (if you held against the mass carefully with your fingers) and only left the hole. Let it dry until hardened, maybe two days. Check that the plug fit. If not, drill it up with an 8 mm (regular steel drill without impact). A bit of PL400 glue, first in the hole, then on the plug, which I slowly twisted in to get the glue into the hole. Let it dry for one or two days and then mount with a screw. It seemed to work well, and the plugs in these holes showed no sign of rotating with the screw. Used half-long plugs (fischer SX 8x65). The trellis is up anyway!
