How do you hang a radiator on a crumbly/lath plaster wall?

[Stanios]

Dreading going back tomorrow and facing that bloody wall. Its not lath its like the plaster you get on it that just falls appart. Its external so must be some kind of crap brick. God knows how they made them in the 1930s

I have used something similar to the above and fixed threaded rod into bricks before and then just drilled out the holes on the bracket and secured with nuts. That was to hang a 600x2000 K2 on a crap wall. Not had a call to say its fallen off so assume its still going strong 5 years later

You must have the old lime plaster walls about 15/22 mm thick .

Could I use that my finger sized hole?

Get a piece of ply 12mm thick stick and screw that to the wall first get it painted then you can hang the rad

I had one that partitioned into a cupboard on other side of wall.

Wall was just falling apart.

Multi tooled into the back of the wall and put internal battens in. Cavity foamed the incision, cut it back once dried and skimmed over.

This may or may not help but it's worth a mention.

Clear a good sized hole in the plaster ( fist size). Clear out all the loose debris and drill into the brick/stone, to give a good 2"-3" depth. And a good width if you can like a brick joint, or if there's one there, clear it out.

Fill that hole ( pushed in well and filled level with plaster surface). With a mix half Portland and half bonding.

It will set fairly quick and give you an iron like material to drill and plug.

does that make sense ?

Try the mix first to see if it's useful to you. Before you open the wall up more than it is now.

I can kind of picture what your problem is but I obviously haven't seen it.

Whats Portland, a rapid set cement?

No, normal bag of cement

Like brickies use

Cement and bonding ( plaster)

Mix the powders first then add them to water.

Not much water
