[Farmelectrics]

A jigsaw, a steady hand, dry liners and a sh!t load of patience!

If cant fix metal backboxes grab some bonding and stick it back.

Had to do this on a wall once.

Its not pretty but it works (mate was telling me sometimes its the only way)

House is falling to bits you see

You forgot the patching plaster. And I would change the jigsaw for a multitool.

Haha another way is to befriend the plasterer, theyre always after flex for an outside light or cable to connect a cooker, once you have a favour to call in get your hammer out, ask them to patch the hole with plasterboard and get your padsaw out, job done haha!

or do it yourself, its not hard to do it, if your bad at plastering then buy sandpaper as well

No quick fix, sorry. knock it out as little as you need, and get a noggin in there.

I would never fit dry liners to lath and plaster,but maybe times have become more adventureous.

Try spring toggle bolts to hold the box onto the lath. you can push them between the lath turn them by 90 degrees or stick a piece of 3ply to the cleaned up lath if the plaster is thick enough and screw onto that. unless youfind the supporting frame location first and fix it to that. Re-aplying the plaster reduces the flex of the lath. each method has worked for me.

Are you trying to fix a surface box to the laths with leaving the plaster in place?
If so use the thinnest screw as possible, this lessens the chances of the lath splitting!

 

[Gazthesparky]

If trying to fix a box to the surface of a lath and plaster wall always drill a small pilot hole in the lath then screw in a screw this then means that the lath doesn't split but the screw grips tight

This has worked for me in the past - there are a lot of old houses in my patch.
Mark and cut out for a metal back box using a sharp pad type saw using the back stroke to cut and try using a piece of board pressed against the wall adjacent to your cut to help support the plaster and stop it breaking away. Then, cut a batten twice as long as your hole and fix it to the wall the other side of the cavity with multiple screws from the other side, I know this means a few small holes to fill but you will then have a really secure fixing for your back box. I used this technique recently in a 200 year old house to mount a shower isolator with 10mm t+e cable onto a wall made of reeds and plaster. Worked great.
