lathe and plaster --- Pulling cable drops---

[tuckermot]

Hi all
I am going to start rewiring a 1930,s house in 2 weeks time ,the upstairs dividing walls in the bedrooms are lathe and plaster .I am going to be pulling the upstairs lighting feed to all the points and dropping the switch drops before chasing as going to leave the house running as its ocupied.I have not come against lathe and plaster walls before i can sort back boxes out using dry line back boxes but not sure if i can cut out back box and pull the cable from the loft through the middle of the lathe and plaster with draw rod and in to the dry line back box how do you do it ??

How big was Stanley's knife then Richard ?

1930's places can be a pain as everyone always changes the way the doors open so no draw wire to use for the switches.

As a complete aside to the thread...
if you can get to the back/inside of a L&P wall, saturate it in 1 to 10 PVA, they firm up beautifully.

Lathe and plaster can be a nightmare. What I've done in the past is use surface mount pattress, if possible, or cut out a section of lathe and plaster between uprights (using fein multitool) replace section with plasterboard, including noggins etc, cut plasterboard for dryline box job done. Making good is required but the finished job wil, IMHO, last longer than just cutting out the lathe and plaster, which will reduce the structural integrity of the wall.

Got to Love the Fein multi tool. Has become a essential part of my tool kit!

Drylining boxes don't usually work with L&P - you'll probably find the plaster is too crumbly to provide a good base for the box. Best is to find an upright, chop it out a bit and countersink a metal box (unless the plaster is deep enough, which can be the case). Be prepared for patching up round the edges because that plaster can crumble away, especially once you start cutting through the lathes.
