I want to put up shelves in a bedroom in my 3 year old flat.
Before drilling the holes I tested the wall with a metal /voltage detector.
On a metal seting it buzzed up and down the whole wall - it's an external wall.
There was nowhere on the wall that doesn't appear to have metal behind the plaster board. How can this be?
I tested the detector on an internal wall and it works fine.
Any ideas please?
