Plaster adhesive over cables

[James94]

Just helping a family friend to hide some new tv and lighting cables in a dot dab wall. The question is can I just fill gap straight over the wires with plaster board adhesive, will it cause any harm to wires and would I have to apply a coat of plaster over the adhesive or would it finish similar to plaster for painting.

regards. James

The mains wire dont look like it is 50mm deep from the surface. So as a minimum it will need a capping over it.

Plastic or metal caping?

I always do metal capping, as i dont see the point in the shite plastic stuff. I can see the grey mains. What are the others ?

If the mains cables are protected by an RCD then I don't think they need any mechanical protection even if <50mm from the surface. If they did, I don't think metal capping would count as it's still no match for a nail? I'm sure there's a resident spark on here who'll know chapter and verse.

 

Drywall adhesive can be smoothed and sanded, but whether it'd provide as good a match to the surrounding area as others plasters I don't know.

One or two original cables which are the ring main these are slightly deeper than the ones we have laid in the wall. Not sure if capping will fit very well  was hoping we could just plaster them in.
