Hi all,
We are having some sockets added to our house, and as such, we needed to chase the brick walls in preparation - I have had the week off and have done this in preparation for the sparks next week.
All of them have gone well, except for one. At the top end of the chase, there is a slight crack (hairline crack), about 4 inches in length and at the end of the crack, the wall sounds hollow when you tap it over an area about 3 inches square.
Annoyingly, this chase was for a flex outlet for a wall mounted electric fire, and of course, the hollow sounding area is exactly where we need to drill. My worry is, that when we do, the plaster is going to fall off.
Ideally, I don't want to remove the plaster, but I obviously don't want the fire to fall off - if I successfully drill a hole and fix the fire to the wall, is the plaster likely to stay in place? Additionally, should the plaster fall off after the fire is mounted, will the fixing remain securely in place? The plaster is about 12mm before the bricks, and the fixings are 60mm in length. There will be 3 other fixings in a 'non' hollow part of the wall.
Any ideas as to how you guys would proceed?
