When our electrician rewired the house he drilled holes in the plasterboard (about the size of a 10p piece). These are now visible beneath most of the plus and some light switches. I can only assume that he drilled them in the wrong position to begin with but this does leave me with a problem. What is the best way to fill these holes? What can I put in the holes to give a firm backing for the filler? BTW I was going to use 'Easy Fill' which I've been told is easier to use than pollyfiller and gives a better result.
Thanks
