Plastering wall chases and deep hole where old socket was

[PhilB65]

Hi all,

I am in the process of updating an old kitchen, and need some advice.

The electrician has chased and capped the new wiring and sockets, but I now need to plaster over the chases and a deep hole (2 inches) behind one of the capping where the only socket was (hence the reason for the makeover).

What plaster should I use, and would I need a different one for the deep hole. I was considering one-coat, but some feel the finish isn't that good.

Any help would be very appreciated.

I would wet the deep recess, fill it to about 3mm shy of the surface with mortar, then plaster, onecoat should be ok. Mind you, that said, that's how I'd do it!

On the right track but that's render mix not mortar. Bonding plaster is probably a better bet, is easier to use & will stick to the capping better. Build it up no more than 10mm thick at a time, allowing each layer to set but not dry out; allow 2-3mm for the finishing plaster as suggested. Stick some reinforcing tape down both sides of the join (or it’s likely to crack again) & use Multifinish to blend it out over the surrounding area; you can use one coat plaster but IMO, it’s truly awful stuff. Make sure you give the recesses a good douse with PVA, let it dry & then douse it again before you plaster. If you’re re-plastering the whole wall, skim the recess out flush with the surrounding area, tape & then skim the whole wall.

Many thanks,
I will try that. As you can gather I'm a total novice at this. Have a plasterer to do the ceiling, but money is getting a little tight to complete the rest of the jobs.

Ta much
