I use a long handled scraper (the Stanley knife type)to skim gunk off
plaster. You need to keep turning it over to keep a sharp edge, and
wiping it clean, but it beats the hell out of washing. It also gets rid
of any gritty bits and leaves you with a baby's bum surface.


Hey - I think I've seen those in B&Q. OK - I'm with you here. So you
don't do any more than a cursory wash off afterwards, if at all then?


Usually not at all. I might quickly rub down with sandpaper when it's dry


That sounds really optimal. That might make the difference between 1/2 day
and 1 day for a medium sized ceiling which is not to be sniffed at (I've
got 3 to go).

Walls aren't so bad, as washing down is easier, but I'll try this trick on
then too. The advantage with scraping is it knocks the surface off the
paint too, and finds some of the loose plaster(!).
