Feb Blue Grit is cheaper but the grit isn't as fine as WBA, last year I was getting it for £22 for a bucket of about 10ltr.

Yeah we have been using bluegrit recently and its nice to roller on but you seem to use a lot of skim we just did a 3 bed house and had roughly 30 bags of multi in for it ended up using 45 bags and went over on the time scale by a few days.

Yea i've found this also...use alot more multi cause of thickness of grit, and the plaster hands probably due to thickness, no suction. Just have to hit bigger areas.

Is the grit in plasprime finer than blue grit?

what are you re-skimming?
If you're going over old lime work then I'd recommend using an external stabiliser (clear, water based one) rather than a bonding agent.
Why? Cos it's much quicker and probably cheaper - the stabiliser goes a long way and it soaks right into the old plaster pretty instantly. I've been letting it dry proper for half an hour or so while I get on with something else. Then I PVA with a 1:3 mix, let it tack up and skim away. I can easily get 2 gauges out of it and the multi finish behaves itself.
Bonding agents are great, but they have to really dry properly. On the plus side you can't beat them on artex.
PVA's got it's limits on old lime work, you need to really let the first coat of PVA dry and keep applying subsequent coats. Before I used stabiliser I was putting about 3 coats of PVA on. If it hasn't at least gone tacky it'll start to misbehave, and you've got a real wait on your hands waiting for 3 coats to sink in and seal old lime.
Whereas stabiliser, wack it on, pva and skim. Quick and effective. The stabiliser seems to really seal the old lime work, it sets a bit like a clear lacquer or varnish, significantly reducing suction.
Oh yeah and it seems to deal with distemper fine too. Only draw back is it stinks and it's got some VOCs in it.

Spunky Spunky wake up Spunky you're having a nightmare wake up.
Yes that's right you were saying spats and plastic trowels were good for skimming.
