Back Box In Hollow Wall Installation

[swaRRR]

Plasterboard adhesive - doesn't shrink when it dries so it's perfect for this application. Whack it in there, sink your metal box into it so it's flush and let it dry. Make sure to grommet your entry hole before putting the box in or make sure the entry hole is completely free of adhesive before you walk away from it.

This stuff would be far better and will not allow the box to pull out with the plug: Rawlplug R-KEM II Styrene-Free Polyester Resin 300ml - https://www.screwfix.com/p/rawlplug-r-kem-ii-styrene-free-polyester-resin-300ml/32863?

Just done a Rewire exactly like this, literally finished it yesterday

knock the horizontal lips off the adjoining blocks flat to the back then
just cut 2x 4 inch piece of 1x1 wood batten(stuff that’s used in packaging for integrated ovens is best) and liberally no nails them to the flat back of the blocks(one above and below the horizontal lip of the block is best but it’s gonna depend on whereabouts you chase in) don’t try to glue them to the rough lip only the smooth flat bit!!)

leave it until the next morning then just fix your metal standard back boxes with 1in x8 screws

sorted and solid as a rock, if you use 35mm boxes it should work out near as damn it to flush of the wall

when I bond the chases afterwards I always make sure I squeeze loads in around the socket boxes to give it that bit of extra support but it’s fine honest!!

if you think your gonna cut a plasterboard box Into it your dreaming

Out of interest what multi tool blade would you use to cut through brick?

We are talking about terracotta hollow block not brick, but for the hollow block I use a Carbide tipped hole saw to start and then these to trim the hole : Carbide Coated Blades for Fein, Bosch, Makita Multitools | Saxton Blades -
