Hello,
I promised to help grandma put up curtain rails. Someone else has previously drilled wall plugs into the wall with rather poor results. (Loose and can't be tightened...)
What kind of wall is it?
It is an inner brick wall with some form of outer layer about 4cm thick. I can't figure out what it is, as gray/white powder comes out of it. But I think it might be lightweight concrete or something like that. The house is a city center building (stone) from the 1890s. It feels quite porous (could be old drill holes with filler or something).
How much will hang on the wall?
Two curtain rails (Kirsch) at 10cm + 15cm from the wall. An inner light curtain and an outer blackout curtain. I don't think the combination weighs more than 10kg in total.
Choice of plugs/screws?
I'm not really sure what to choose. I'm considering a screw about 40 x 4 and a regular nylon plug.
So tips & suggestions are welcome!

It's probably plaster coming out, that was done back in the day, but if it's 4 cm, it won't be really good with a 40 mm anchor and 4 inch screw, you need to get into the brick so it grips properly. How many screws in each bracket?
A tip: drill an additional 4 cm into the brick, insert two anchors one after the other and use longer screws, at least 70 mm, and it will hold well.
PS. Keep in mind that when you drill into the brick, grandma will hit the ceiling, it becomes red almost everywhere. Keep a vacuum cleaner nearby when you're drilling to catch 95% of the red dust, there will be a little left around the holes. Do not wipe with something wet, it becomes 10,000 times worse. Light vacuuming and brushing usually works well.

A plug is a plug as long as it's the right size and it's perfectly fine to place several in a row to fill the entire hole, then the screw won't be hanging in the air at the end.MDIST said:
Plastering is not the best for attaching things to. 4cm plaster does seem quite deep!
I think it will be an 8cm long screw and nylon plug for that? Or do I need a special plug when I'm going into the brick?
