Type of fastening material in lightweight concrete for ceiling mounting of curtains?

[Belmlu]

Hello,

I have a friend who is going to install ceiling-mounted curtains from IKEA's VIDGA series. From experience, I know that it can add some weight depending on the curtains chosen, and there are children involved who will probably pull on the curtains sooner or later.

Before reaching out to us, they had tried a regular drill on the advice of another friend they consulted with, but the result was just a big, porous hole. I haven't seen it myself, but I'm thinking it might likely be lightweight concrete. However, I don't know what's underneath.

I'm quite new to both drilling into hard materials like this and installing things. My initial thought is lightweight concrete plugs, even though I'm not sure if there's anything behind it. Is there something else that would be more suitable for this probable material and this type of vertical load?

Thanks in advance!

Anchor adhesive with plugs is what I would recommend..... You need to do it right. Check the instructions (and follow them)....
I also found these, which seem simpler, but I haven't used them myself..... I know anchor adhesive works.

Use the GB plug, it's sufficient for attaching a curtain to lightweight concrete.
You mention ceiling-mounted, which sounds a bit strange with lightweight concrete in the ceiling, but if you can drill with a regular screwdriver without an impact, it’s likely feasible. If it's "real" concrete, a regular good plug like Fischer Duopower is usually enough.

You mentioned ceiling-mounted, which sounds a bit strange to me with lightweight concrete in the ceiling, but if it can be drilled with a regular screwdriver without hammer mode, it's likely that. If it’s "real" concrete, a good regular plug like Fischer Duopower will do just fine.

Yes, it could very well be something else too! I just received this picture and additional info that it was possible to drill with a regular drill but it stopped quite abruptly. So it's probably some other material followed by cement?

Is it plaster on concrete? How far can you actually drill?

Regardless, a curtain rod requires quite a solid mounting. Curtains can be heavy and you pull them back and forth. Then they get a little stuck and someone tugs at them. There's quite a bit of force on the brackets....

if it had been lightweight concrete, it would have been fine to drill with a regular drill and screwdriver. Now, apparently, it didn't work, so you might suspect that there's concrete in the walls. Bring out the small hammer drill and small nylon plugs, and the job's a done deal.

It's concrete. A rotary hammer and concrete construction are what's needed. Use a 6-8 mm Duopower with the right diameter and length to support several hundred kilos per plug. (Or group of plugs if they are too close to each other. (If you want to be picky))

It's probably concrete that's been plastered. Then regular plugs work after you've drilled further into the concrete with a hammer drill.

hammer drill

we stopped using it when the 20th century came to an end. Especially in apartment buildings, it's hopeless. A small rotary hammer is the right recipe.

Not saying it's wrong, just asking out of ignorance, but does this also apply to vertical loads? Or don't you have to consider vertical or horizontal loads with these types of loads?

The extraction value is always calculated directly regardless of how the plug is positioned. So it doesn't matter if it's ceiling, floor, or wall, it's the same value.

It's much easier to pull the screw straight out than to pull the screw out by pulling perpendicular to the screw, that's for sure. But if it's real concrete you have, you can be completely confident as others have written with a 6mm plug that you tap in and then screw in a screw. It holds like a rock!😀

It is most likely concrete that is plastered. Regular plugs work after drilling further into the concrete with a hammer drill.

concrete ceilings were not plastered, they were spray-painted with filler paint.
if it is a plastered ceiling, it may be a stuccoed ceiling, common in older apartments.
