Attach stair railing? Provisional solution with minimum effort

[Vrana]

I have a stair railing from 67 that's screwed into concrete, and over the years, the hole for the middle screw has widened and is now loose. It's held in place by the other two. Can I fill the hole with something to screw the screw into so it doesn't wobble? I'm afraid the other two at the ends will become loose too.

My conditions: utterly tired of anything renovation-related (it usually passes) the wall is an overpainted tapestry and any large interventions with subsequent plastering will stand out quite a bit, but maybe I have to swallow that. Broadly plastered 80 sqm tapestry may it burn. It's a solid screw drilled directly into the concrete, and the hole is now porous and crumbling. Can I fill it with something and then screw it in again? Preferably something simple, inexpensive that makes it sit firmly until I tackle renovating the staircase. Sometimes I happily consider setting the whole thing on fire, but unfortunately, concrete doesn't burn that well.

Suggestions? Mockery?

This is not right, but press in a bit of kemankare into the hole and insert the screw before it hardens. Then it won't go anywhere.

If the screw is in concrete, can't you just take a larger plug?

Chemical anchors were new! Going to test immediately!

The thing with plugs is that I haven't gotten them to work plus I would have to take the whole thing down again. Regards lazy

The thing with plugs is that I couldn't get them to work plus I would need to take down the whole contraption again. Regards lazy

Unfortunately, you will be disappointed with chemical anchors. For it to work, you need to take down the railing, clean the hole and remove all loose material, blow out the hole thoroughly, and then use the chemical anchor. It's unlikely that a shortcut here will leave you satisfied.
