If filling in holes etc when is it acceptable to use expanding foam? Or better to fill by layering it up

Bobbo in reply to @musa

Depends on what type of hole you're filling and the finish you would like to achieve.

Generally speaking expanding foam products are intended to seal penetrating gaps for example round window frames, or round penetrations between internal spaces where firestopping is required.

Thanks. I have a hope where the socket has been placed. Internal wall which is lath and plaster. The previous owners seems to have cut into the end of the wall to lay the wire and fillered over it. So has I’ve gone to remove the wallapaper it’s pulled it off so wasn’t sure to how to fill it
