I had some bags that left grit in bottom of bucket when I was cleaning it out. I just leave first coat longer and put tight second coat on and leave it longer and seems fine
All this talk of "grit at the bottom of the bucket" puzzles me greatly.
When plaster was decent, all those many years ago, it was 100% coarser than it is now and always left plenty of grit at the bottom of the bucket. I'm not talking about large bits of grit that are a problem, it was just generally coarser.
This all changed when Multifinish was released as it had to replace Carlite Finish, which was capable of dealing with the high suction of Browing. Carlite Finish was always known for showing up all the water marks and drying out very much how multi does now. And I'll tell you now that no spread back then would have chosen to use the slimey, snotty (sound familiar) Carlite Finish on anything other than a high auction background. If you use multi over Hardwall it works absolutely lovely.
IMHO Multifinish has gotten even finer over the years, making it even worse to use on low/medium suction backgrounds.
Now here's the bit that baffles me most; BG have at some point decided to make Board Finish finer than in the past, this can, IMO, only be for financial reasons.
So in summary, 90%+ of plastering work carried out is on new board, PVA or a grit type product, all low to medium suction (at best) and yet the plaster we have to use is best suited to high suction backgrounds.

any comebacks to my thoughts?
