Dry wall boxes - before or after plaster ? Opinion

[batty]

Now I always used to do this, saves raised heart rates at second fix stage, but a couple of plasterers have moaned as the plaster slumps on the edges, more so on the down lighters due to gravity. Partly down to the way the trowel sort of sucks the plaster off on the way over the edge, partly down to the fact that the excess gets pushed in the hole so there's more weight on the edge of the hole whilst wet which pulls the corners down. Makes sense, but then plasterers are country folk so **** 'em.

Language Timothy.

I always cut my holes first, at least even if I dont fit the box, but usually do fit box too.

as for downlights, always always cut before plastering, that way if you do get one needs moved for whatever reason you can patch the hole in and it will never be noticed once plastered, if you try patch it up once plastered it sticks out like a sore thumb as the mix will be slightly different.
