The answers staring you in the face mate if you take a step back and look at the the situation logicaly.

If the background was a high suction background then yes by all means use the same mix to 2nd coat your work as in effect the first will have pulled in and the gear your laying in is wet enough to act like a new ie seperate mix.

However if your saying that the background was paint then it is going to be of a low suction so obviously your first coat hasnt pulled in sufficently to accomidate your 2nd coat which will already be starting to pull in before applied leaving the situation youve described ie your plaster smudging over your walls etc.

Not having a dig mate just trying to explain how i see it from your description. I think over the years ive had just about every imiginable bad day going with skimming etc and as much as its nice to pin the blame on **** gear through my experiance in 95% of the time i always find that when ive thought about it after the biggest factor is human error ie bad judgement.

Spot on mate, first coat wasn't ready.
 
It's a shame coz the room is a bit to big for a big set so I broke it into 2 quick ones plus it saved me moving buckets etc in between trowels.

see to me that is your problem "Quick Set" plaster sets a that same rate more or less no matter how much you have on, treat each "set" as the same there are no quick or long sets, you basically tried to rush the job by doing "quick" sets and ballsed it up :RpS_wink: lesson learned
 
Back in the days of SirapiteB I used to mix a small bucket of gear up at home, and then when I got to site about forty minutes later I'd divide it into three. One section for each bucket of the first move. A quick spin in the water to break it down and away we went. This sped up the first move no end and enabled us to get three moves in on a winters day without messing about in the dark to much. There was no detrimental affect to the finished surface at all.
I've never tried this with Multi but I can't see why it wouldn't work just as well.
 
from what i can remember sirapite hung for ages,maybe to do with the s&c aswell,but i have tried similar to what you did with multi n it goes lumpy.
 
Quite often to quick sets when I have to be tidy so I only mix once, have you had this happen to you or is that your eductated guess Ashleyscoob
Tried to do it only once and it went s..t just like yours m8 it can work on plasterboard or a surface that will draw the skim in but on silk paint with bond it on you have to put a thick first coat on its not going to pull quick so coating with same mix is a no no just have to wait
 
Lesson learnt, no more quick sets on non porous backgrounds, I hate silk paint even more now. Intact I think I'm gonna knock the quick sets on the head totally
 
Also forgot to mention I just came back from there and the room looks pretty tight, nice even egg shell look and the angle all look good just a bit baggy on one bead and the odd tear which I can aims out, still was the day from hell but a least I learnt a little and my work is ok.
 
Started taking too much off on first set got about a couple of tennis balls on first trowel on a bag and a half and obviously noticed it didn't trowel well after that so on my second set I let it pick up and didn't take much off when I did trowel it but it still didn't go well it was like any pressure would get **** loads of fat and if you let it pick up then any pressure would tear it. It didn't go hard until a couple of hours after I mixed up which is about right with the multi I've been using recently but I did notice that it was still soft if you squeezed it really didn't feel nice, have you ever had problems with damp bags.

i noticed mine was still soft after a few bevvys squeezing didnt help either and didnt feel nice and i ended up with a damp bag aswell must be the material i also go hard after a mix but i keep getting a groove all the way down my walls around waist height anyone else had this?

Going hard at waist height after a mix, which doesnt soften after some squeezing ? Should lay off the viagra mate.
 
Don't think it's anything to do with laying in with the same gear. I do this 9 times out of 10 and find that generally the jobs where I get tearing going on.. are the ones where i make a new mix to lay in with. Sometimes you just get a dodgy background or a dodgy batch of plastering. I know how you feel though, never nice to leave a bad looking finish. Just superficial though, once it's painted it'll probably be fine!
 
Had a pain of a job the other day, large landing/staircase/hall. Underfloor heating was on full whack when we arrived, even though they turned it off I was sweating cobs and wet through upstairs - the skim (multi) was going in like mad even though the walls had a good coat of pva. It was that bad we were just managing a bag of skim between two of us.. It wasn't crazing though so it wasn't through too much suction. Downstairs wasn't too bad as we had the front door open but still dried a lot quicker than normal. Glad when that job was finished (they gave us some bottles of beer when we finished, mine soon vanished when I got home).
Back on our other job in a renovation and the multi was flowing nicely, especially on soundblock and water resist board.
