I feel a bit dirty asking the question, but here goes anyway as it's always good to have an open mind. What do people think of gluing cables prior to plastering. Two options come to mind: Hot Melt Glue: https://www.gudfor.com/en/products/electricians/380 Hot melt is commonly used to attach wires in non-construction sectors Grab adhesive: like GripFill, Sticks Like, No More Nails, Instant Nails, ... . A 350ml tube would go a long way (>100m) with 1ml blobs every 300mm. Epoxy: sets hard so that may be a benefit. Clearly unsuitable for permanent fixture, but prior to being plastered over? I did a basic test of a grab adhesive (GripFill yellow which is no solvent) and it holds to blockwork as well as a clip does. A 2.5mm2 cable in a 10x10 mm chase with a 1ml blob can drag a block across the floor in shear. The main benefits would be: Narrower chase as no need for space of a clip Quick to install Cheap (£2 per 100m at 300mm c/c)

Yes I see the migration issue being difficult to get a credible answer on unless you find a manufacturer that produces both the cable and the glue stuff - a bit unlikely.

It depends what you are trying to achieve. I have been known to mix a little plaster (old going off stuff) and put blobs in for such use (below finished surface) sufficient enough to hold the cable in place whilst plastering. Or even a piece of floorboard (drill and plug a couple of places) and a bit of cardboard spacer between floorboard and cable, then put some blobs of plaster in where required. Alternatively a little bit of spare insulated conductor put in diagonal then twist slightly to bite into existing plaster channel in order to hold whilst your blobs go in.

Sometimes an effort but often worthwhile if the material you are working with has problems with initial fixing of clips/plugs/capping etc. 1,0 to 2.5 T & E is not too bad but other sizes create more problems methinks
