Choice of plug, glue the plug, screw in directly or wait?

Happy New Year!

I'm going to install this towel rack (https://www.ikea.com/se/sv/p/brogrund-handdukssvaengel-3-armar-rostfritt-stal-60426707/)

Since the rack is only mounted on one side, and when used, the holder's arms are twisted and weighed down, I want to ensure that the holder is securely attached to the wall.

It's not concrete, but some form of lightweight concrete, black in the wall (apartment building from 1948). Then tiled.

Which plug do you recommend? How do you best glue the plug, and should you tighten the screw immediately after filling the hole with mounting adhesive/silicone and inserting the plug, or wait until the adhesive/silicone has dried?

Is it enough to use silicone (I have at home) or does it have to be mounting adhesive (if so, which one, 400, 600, etc.)?

Does it have to be wet room adhesive/silicone, or is regular fine, since the rack is not going to be near the shower?

Or how would you do it to ensure it holds well even if you twist/use the rack every day? The plumber who moved the mixer and installed the overhead shower seemed to glue the plugs with something I forgot to ask about.

Anyone have any tips to share?

Plug designed for concrete, and any silicone should work just fine.

As long as you don't use a plug that's too small, there's a very small risk that the screw+plug will come off the wall, no matter how wet the towels you hang on it are.

Plug intended for concrete,

Plug for concrete becomes a nylon plug. Here it might be more suitable to use a plug for porous materials, they usually hold better in lightweight concrete/leca.

Plug for concrete will be a nylon plug. Here it might be more appropriate to use a plug for porous materials, they usually grip a bit better in lightweight concrete/leca.

Thanks. Any specific plug for porous materials? There seems to be several different ones. The hanger is only attached on one side. Then there are three rods that can both be rotated and extended. So one attachment point on one side (albeit two screws) and then you probably rotate and extend and retract the rods daily.

Should you screw in the hanger right after inserting the plug with silicone/glue, or should you wait until the glue has cured overnight before screwing in the hanger?

This plug is often used in lightweight concrete, etc.
It is triangular instead of round so that it grips the substrate in a better way..

Thanks. Any specific plug for porous materials? It seems like there are several different types. The hanger is only fastened on one side. Then there are three rods that can be both turned out and pulled out. So partly a fastening point on one side (albeit two screws) and then you probably turn and pull out and slide in the rods daily.

Should you screw the hanger immediately after putting in the plug with silicone/glue, or should you wait for the glue to cure overnight before screwing on the hanger?

Screw the hanger in before the silicone cures, otherwise it won't seal properly.

Here is another lightweight concrete plug:

Fisher also has something called "GB"

Regarding the sealing, you can see here how it is done. In your case with a solid wall: Drill, seal, insert the plug, seal (i.e., fill the plug), and finally insert the screw. Sealant for wet rooms sounds appropriate, it doesn't have to be silicone.

Regarding the sealing, you can see here how it is done. In your case with a solid wall: Drill, seal, press in the plug, seal (i.e., fill the plug), and finally screw in. Sealing compound for wet rooms seems appropriate, it doesn't have to be silicone.

Thanks for the info. What do you mean by solid wall? It’s just that it's tile, then lightweight concrete/leca/svart mostly around. Sometimes cavities. Bad experience sometimes in other parts of the apartment in the non-bearing walls.
