Resin fixings for someone new to them

If you're drilling into rubble and voids, then resin may all "escape" before it sets, so not help ...

When I needed to hang a big radiator on an outside wall (i.e. a thick one with a lot of rubble) I ended up using four lengths of 6 mm studding, each about 300 mm long. IIRC I injected the holes with relatively cheap decorators filler before banging the studs in, this left them sufficiently well anchored once it had set. Beware with a TV bracket that the relatively short vertical spacing means that there will be a force trying to pull out the upper fixings. You should be safe with really long fixings because if they start to come out, they will jam before they come out completely.

You don't want them to come adrift when supporting an expensive TV!

Some people claim success with frame fixings. Sometimes they work well, sometimes they don't. You can get fat wall plugs (~15mm dia, 50 mm long) that will take coach bolts. These are good, especially if you can make sure you are going into the middle of a big block of stone. One approach is to knock the plaster off to expose the stone, then set in a suitably large piece of plywood, and screw the TV bracket to that. Not really visible after filling and re-decorating.

I remember drilling into my then GFs Victorian terrace..and being surprised when a whole half-brick fell out, and there was daylight outside.

Basically mortared the half brick back in, made the holes and skimmed a bit of plaster over it.

Moral; As with cars, keep removing anything that isn't sound and rebuild from there.

Car body filler is cheaper and better than most resin fixings as well.

It is so "last decade" to mount a TV on the wall. Look at nice minimalist stands.

I've used Fischer resins before and they work well. If you have a look at their site, there's lots of information. One of the things they make for walls that might have hollow bits is a perforated sleeve to restrict the spread of resin.

It's all fairly obvious, except for one thing - the hole must be blown out of all dust. This is done by pushing a small tube to the back and using a puff of air. I suspect a can of Canned Air would do the job very well? (I have a little pump as I did a fair few).

You don't have to use the special studs - any threaded rod is fine, but it's worth degreasing it with a bit of meths.

That's what they make these for:

Thanks, only used resin fixings once (to anchor the sole plate of a stud wall to an especially weak mix of floor screed)

Yes I'd be surprised if walls are just rubble as how would they actually sty a wall if that were the case? Brian

The walls of my daughter's house in the Cotswolds has rubble filled walls about 2ft thick.

When I describe the walls as being rubble, I'm going by the party wall which I saw in my neighbour's house where the plaster had all been stripped off and it had been made a feature.

It seemed to be made of general large pebbles and large bits of rock with lots of mortar in between. This might be explained by the fact that it's in a seaside resort.

The walls are about 22 inches thick with brick on the outside. The last Victorian house I lived in had solid 9 inch brick walls, this one's a fair bit warmer with its thick walls.
