Hi
As in Q1, refitting a botched kitchen installation, there are gaping holes in the masonry walls where I have ripped out old backboxes and tons of polyfilla. The new one would have far too much room and will sag in any direction wanted. As I don't seem to be able to nail them into position what is the secret for fixing them? Could I use PU foam and foam them in? That's probably not OK with the regs but I don't recall anything said about such practical matter there!?

Counting on you,

Michael
