Metal flush boxes

[chocolate]

Does anyone know a tried and tested way of fixing a metal flush back box into a brick wall that has been completely mashed ( rather than a tidy bit of knocking out ) by a non-electrical tradesman ??????

Unfortunately, what remains of the surrounding brickwork is in no way secure enough to be drilled for a fixing.

I have a disheartened customer at the moment . . . .

Once you realise you only mix a little at a time and use it quickly it's allright. Mind you, if you have a lot to do waiting for the stuff to set, may not be an issue.

top tip ,buy a bag of bonding adhesive ,the stuff they use to bond plaster board to block walls.
i use "lafarge" its white & sticks like **** to a blanket.
rip open top of bag and dump in yer shed/garage.
when its matured enough ie had a bit of damp it will go off solid in about half an hour which is ideal for setting boxes in crappy walls & hollow blocks.
to think i ****ed about for years with sand and cement waiting forever for it to dry.

earth tail from socket to box lug good practice

If it goes off that quickly it sounds good. - and only cost the same as plaster!

yep sets in 3hrs fresh out the bag or 30mins to an hour max depending on how long its been out in the open maturing.
time is money.

A touch of dirty (cementy) water or a little cement in the bonding makes it go off much quicker!
