OK OK i gave it ago ta day as the other plaster i have with me sometimes does this.. i did medium a wall (down the stairs) on an over skim. just gave it one PVA so the suction was still high.. put the coat on gave it a flatten clean up the edges and mixed up the left over with with more water and a hand full of multi and put it on.. troweled up very nice with in 30 Min's.. .. what has he garn and shown me !

i do think from this i may be leaving the first coat way to long and from now on will try and get the second (fresh batch!) mix on quicker.. find it easier to get at better finish when its all fresh and wet on the wall..

fort id mention this 2 you all! i am now in the cowboy club

dont remix plaster it will set quicker and i thought you set this club up;)
 
it went a lil stiff so i mixed it back up .. i new it would go quicker . worked well as i wanted to get home quicker as well
 
this was an emergency .. i could't be botherd to plaster all day on my own again cuz i was to greedy to leave the other spread at home.
 
I sometimes 2coat from the same mix if not doing large areas
when going over hardwall or browning, by the time the 1st coats on it pulls in pretty quick
then straight over it with same mix but don't need to remix it, i only do this on smaller areas.
The suction helps though, I can see why you had to remix it if you were overskimming.
If it goes a bit stiff on the spot i just mix a fresh batch.
 
i do it both way's...... usually 2 coats out of the same mix, but it all depeneds on the background.
 
two coats out of the first mix every time works for me ;D ;D ;D ;D.............you all sound so serious when you say it .............i do a 8 metre set check me out 8)
 
I allways use the same mix. Ive been at it for years and get a wriggle on if needed so maybe that helps.
 
Only time i mix up twice is on the very occaisonal larger ceiling,even then ill go for it in one if i think i might manage it and if struggling mix a fresh batch up.
Was taught to do it this way,dont see any reason to change

You must mix up big bucketfuls
 
so u lay on a bag, flatten the apply the last half a bag on with out it getting 2 stiff.. i gota say aftter doing a few 2 coats 2 mix l8ly , its not as good as finish as 2 coats 2 mix. but handy trick for the odd wall
 
Why don't you just lay one coat on? why bother with 2 if you are using the same mix? just lay it on a little thicker?
 
free d youve opened a can of worms there mate had this argument 4 yrs ago with the big fella and he gave me an infraction but dont worry dont think its catchy. my point was if your in a hurry or last set on board skim all joints tight then skim with heavy coat and trowell as norm done this for eons and had nay probs
 
Seems people do it different ways, and if your happy and comfortable then stick with it.

My aproach is I decide what surfaces I want to get on, for instance a ceiling and two walls, now a 1.5 bag gorilla bucket will maybe 1st coat the ceilling and 1 wall. We do another bucket and that will 1st coat the 2nd wall and top coat the lot.

So one wall has both coats from the same mix.

Plastering has a set of guidelines rather than "rules", as long as the finished product is right, it doesnt really matter how you produced it.
 
Yea I agree with the above...however you do it though to be competitive these days its got to be as quick as poss so its good that we bounce ideas. I would try to do a whole room in 2 sets...but recently lost a quote to a guy who are did a whole room in one set, one coat then using a sponge float and getting a quality finish any1 else experienced this?
 
You can do that with Knauf/wickes one coat, takes it's time to go off then sponge it up but wether it's one set or two it's still a days charge surely?
 
what if one bloke can do a job in 4 hours and it takes another bloke 8 hours?
surely the bloke who can do it in 4 hours is gonna get the job because he can afford to charge half a days work?
is the 8 hour bloke gonna lose out eventually cos he'll be seen to be overcharging?
never mind quality of finish or tidiness of job, assuming all else is equal, we are now in the year 2009. 'Plasterers' are 10 for a quid, youve got to be good, and youve got to be quick. Charge your full days money for a three hour job if you like, someone else will come along and do the same job for half the price and youll be watching jeremy kyle with the wasters....
1 coat or two, if it requires 2 give it 2, if not....
boards one thing, over skimming usually another... if you can acheive the finish with one coat that makes you the better spread surely?

all that said, i usually 2 coat 2 mix, but these days im tending to 'roll' them so the 'topping' is on an 'as needed' basis...
 
No oasis...weve been down this road many times before mate .....but here goes.
Whereever i can....i will mix 1.5 bags to 2 bags and lay on as many walls as possible in 2 coats as possible (usually this is 2 medium size walls).
ill lay on first coat on both walls,then straight over with same mix no adding water no remixing just as it comes ill then flatten the first wall then the second then clean the bucket out and save a little sh i t for emergencies.
then ill wash the edges,
then ill square it all up.
At this time ill get another mix on and bang 1 or 2 more walls on (same method) with the 2 coats.
then ill jumpo back on the other walls and 1 st trowel them.
Thenback on the second lot of walls and square up wash edges.
Back to 1 walls and wet trowel,
Then back to 2nd walls wet trowel you get the picture.
Final hard polish all done....show me the money honey!!!!

I wont be standing around chattting about the weather or scratching my arse untill the first 2 sets done.
Its then a quick break for me and on with the next sets.
Not everyone can/or wants to work as fast or intensive as this.
This is how my dad did it and he taught me ,its the only way i know,im not saying its right but it's certainly right for me.
If its a big wall or ceiling or im hung over / feeling under the weather etc ill do 2 separate mixes.
But most the time i do it as described above.I can even do most stairwell walls in one hit on my own withthis method.
All british gysum say is apply 2 coats,if youve got the speed and coorect tecnique and know the method of laying 2 coats in one mix there really is no problem.
Its not cutting corners....its all about speed mate.
ive seen lads 1st coating then laying them down.mixing up a second small mix laying on then laying down,waiting for it go off!!!! 20 mins later first trowel sitting around waiting wet trowel then polish.
By this stage ive got 2 walls finished and 1-2 more in the final stages.
Most the old school plasterers on this forum will have or still do it this way.
 
You of all people know what im saying......
10 -20 mins what the difference.Only time i stand around is when im taking a pi ss.
Thats how you get your meterage in 2 coats and earn your money !!!!!
 
One coat doesnt work on re-skimms though. Cos setting plaster contracts and troweling up compresses plaster aswell so basically loads of lumps and bumps from the original wall start to show through.

In fact I wouldnt even one coat on plasterboard.
 
the other benefit of 2 seperate mixes and flattening the first coat is 90% of the time you will get alot more on so you only have to do 2 sets instead of three

Theres +'s and - 's for both ways.Its what style your happy with that matters.The 2 mix method is the way they teach em at college nowdays so lots more people will do it this way
