I had to use blue grit for a job, it was horrible to use and like you said, you have to put it on think. Personally, I won’t use blue grit again, I’ll stick with the green grit when I need it.

I really don’t like blue grit at all, it absolutely eats plaster. Much prefer the bostik stuff that’s green and the bond-it yellow pregrit. Finer grit in both, use much less plaster I find. I fully agree with you saying that plasterers seem to think it solves all problems with backgrounds. It doesn’t. I’ve seen blue grit fail for a few reasons. A bad background is a bad background and needs to be sorted properly.

When I peeled it off (took ages) , the plaster is smooth, very cold to the touch with bits of mould on it. I'm trying to paint it without the lining paper. Do I need to skim it? use PVA or blue grit and skim it again? I'd hire a plasterer, but the property is rural and can't find one!
