I have a light switch where the plaster board around the edges of the face plate have broken away.
I was thinking of using some kind of filler like Polycell to fill the holes but I'm not really sure how I would go about it. Is it simply a case of mixing the filler quite thick and applying to the holes?
I don't know if this is relevant but the back plate behind the light switch isn't attached to the wall in anyway. The back plate seems to be stay in place by screwing in the light switch.
