Hi Guys,

Im just about to have a room skimmed by a plasterer, and before he comes in I have removed an aerial socket that was in a daft place and no longer need for the room....

I don't see it being the case of being able to skim over that, so I am going to have to somehow fill the hole so the plasterer has something to skim over.

Any ideas on how to repair that? I guess I could just leave the plasterboard backbox in there and expanding foam it, but that seems a bit of a bodge.

Any ideas?
 
Not sure the foam route will work as there is a large void between the drywall and what used to be the internal wall. It part of were the dorma meets the original wall, probably about 3~4" deep.


this seems kind of overkill
 
:(

Foam will work ok.

The foam in the first link will work perfectly, it expands nicely, but doesn't go so wild with expansion.

You want something more aggresive, then this one below.

If you can dampen that internal wall, it will help the foam to expand, you should be able to do it in one go, but you might find it easier in two, can be hard judging correct amount to use.

The only reason I thought it might not work is that the hole is half way up the wall, so when I start to foam it, it will just drop down the wall until it either sticks to the interior or hits the floor.
