Leaving backboxes proud?

[Mathew Newton]

And on that basis I figured I might as well make the possibly-an-issue-possibly-not into a simple non-issue and went round the boxes I'd done so far and sunk them into the blocks slightly so they are no longer sitting even the slightest bit proud. The blocks were smooth and a so a bit tricky to scrap off just a mm or two but I found the easiest/quickets way was to roughen up the surface with a scutch chisel and then scrape this roughness off with a straight chisel to provide the required recess.

I know what'll happen now - I'll casually mention the subject to the plasterer over a brew and he'll tell me he prefers the backboxes slightly proud as it gives him something to plaster up to for a neater finish... ;-)

Depending upon the type of block, other ways can be easier, but messier. When building our conservatory, the dwarf walls and partial full-height walls were built with lightweight blocks on the inside and a router with an old bit made short work of recessing back boxes and chasing cables into the walls.
