Hole in external wall

[Mattchoo]

I don't know how to fill up the external wall hole.

I can't remember what was removed here and why, but I've been left with this hole to fill.

Does anybody have any ideas on best ideas for this?

You need to remove and disconnect that cable first of all. Externally for a professional finish you need to get some matching bricks, remove the damaged ones and replace with full bricks. Internally you could just get a tin of expanding foam and fill the void with it then plaster skim over it.

brick, mortar and finish with plaster.

Thanks for replies. My only thought was filling the gap with expanding foam, and steel wool and then putting a false vent on the outside to cover the gap but sounds like I'm going to have to do it properly

Oer that’s rough

The foam and face plate should work. UV light will make the foam turn orange and become brittle, but a false vent will prevent the UV light hitting the foam.

Not the correct way to do it but...

Spray a mist of water on the external brickwork/hole, it will help to dislodge dust and improve adhesion (and curing times).
