SO wanted a fitting put up on the kitchen wall that is plastered concrete block with flints in the concrete. Usual happened, hammer drill went off centre and left a hole big enough to get your head in. No chance with normal fixing plugs. Can you still get that stuff that is a powder/fibre mix that you wet and push in the hole, allow to dry and then put screw in? Is so where can I get it?
...ah but it was based on Asbestos fibre so presumeably you cannot get the original Rawlplug made stuff. There may be a substitute but I'm not aware of it

Dunno - haven't seen it for years. But I never had much success in getting firm fixings with it when it *was* available.
If you use an SDS drill rather than an ordinary hammer drill, you've got a much better chance of getting the right size of hole in the right place.
I use car body filler for that job. Halfords do small tubs pretty cheaply. Goes off in a few minutes, then you can drill a fresh hole.
Very true.
Try this Rawlplug Plug & Repair
If I were to end up with quite a large hole, what would the bond between the filler and the wall be like? I am assuming that the plug would be a snug fit in the filler, but what about the filler to wall bond? After all, it can't expand when the screw is inserted into the plug.
What I have in mind, is something I did in our son's house last week. Drilled a hole right through a double wall, opened up from both sides with a much shorter drill and ended up with 2 hole that did not match :-(
This is the first time in a lot of years that I have not made a match, but it did run through my mind, what would I do if I had to put a structural mounting in the same place as the redundant hole.

Excellent. Sometimes you have to work the filler a bit in the hole so that it binds the dust.
I am assuming that the plug would be a
It has some flexibility, certainly more than plaster or brick.
Gives you an instant repair and allows you to get on with the original job.
You may be able to screw straight into the filler, just drilling a pilot hole, and not use a plug.
Don't know if you can still get them, but I have also had wall plug glue sticks in the past. You pump hotmelt into your hole, then screw straight into it. Seemed to work well on old flakey L&P walls.
