Filling ununsed holes

[Rob_Quads]

In my house there are a couple of old 25mm flush boxes which have cable running to them. The used to be used many years ago as power for heaters wired into economy7 supply. The cables are no longer in use and are dead. Rather than putting a blanking plate over the holes is there an easy way to fill them withouth just filling them with wall filler.

The idea solution although I am yet to find it would be a steal plate that screwed over the plate to then only leave a few mm of filling.

(I know its not elecy but it sort of is)

first and foremost, you MUST ensure that the cables are indeed "dead" and that they could not be reactivated accidentally. You need to sort this bit out first. AFTER that and they have been tested that they are "dead", simple, remove the steel boxes, clip the cables back. Liberally wet the inside of the cavity (ooooh errr!), whack some 3:1 sand and mortar in the hole. Make sure you leave the mix about 3-5 mm shy of the surface, when the mix has gone off slightly, score some lines into the mortar face, then mix some one coat plaster, wet the cement surface again, apply the plaster, use a straight edge to scrape off the excess, let it go off a bit 5-10 mins, then polish.

Lest that's how I do it !!

Alternatively, if you aren't a regular user of sand & cement, and therefore don't want to buy any, having removed the box, cut a piece of wood to a tight fit and bang it into the hole, and then use plaster or filler.

Or turn the box round and put it back so that it effectively fills the hole. Sand the rear surface very well so that it's clean, and apply some PVA to help the plaster/filler stick. This method will, however, upset anyone in the future who drills into the wall at that point and finds a hollow space where they wanted to put a wallplug...
