One coat or two?

Hey fellas, I’d like to get your opinion on something. My boss has told me to apply the plaster in one thick go — first a 2mm layer, then the additional 1mm straight after, with no waiting or flattening in between. He says this still counts as a two-coat job, but I’m new to the trade and it sounds more like a one-coat to me. What do you think?

1 mix = 1 coat.
That’s 1 coating, it doesn’t matter how many times you go over the same area.

2 mix’s = 2 coats.
When you apply a fresh mix that’s 2 coating.

Plastering applied correctly is 2 coating with 2 separate mixes. Any other way is cheating & creating a dodge, but at the same time saying that a “skilled” professional plasterer can definitely make 1 coating work in the correct scenario.

show me someone that bangs on about being 'just as good' 2 coat same mix, or 1 coat only and ill show you someone who has never actually achieved a perfect decent finish in his f**k**g life.. doesnt even know what a decent finish looks like, and when put up against a decent plasterer side by side, will suddenly disappear up his own arsehole and change his f**k**g number.. bloke ive been working for went on about how his plasterer was twice as quick as me..
I rock up on a half finished job, started by said 'plasterer'..
customer now want to know what is going to be done about the previous 'plastering'

Mate I only disagree with you when you're talking b*ll***s.
Any plasterer who doesn't understand that two coats from the same mix is still two coating has never worked at pace on mid to high suction basecoats. Not all skimming is going over plasterboard.

Read my post again and you’ll understand what I’ve said properly mate.





Otherwise it’s the bus stop for you!
 
Being serious on this,it states on BG bags 2mm thickness.
In order to reach that with 2 coats the mixes are to wet and thin and time consuming.
I had a BG rep down on site and asked him to demonstrate,his reply was he is not allowed on hop ups ect .
 
Cockney,i do understand you.
2 coat plastering is the best finish.

F--king bus is late oh wait a minute im standing in a homeless shelter. b*ll***s!

When putting “another coat” on with the same mix all your doing is laying the first coat down stupid boy!!

1 coat clown lol.
 
On little jobs (cos I only do little jobs) I knock the a bit of water into the old mix and use that.

Is that the same mix? Is that one or two coats?

I'm so confused. Please help.

From what I understand, one of the main purposes of applying two coats of plaster is to improve durability. This is achieved when the second (fresher or wetter) coat bonds with the first coat, which has partially set. The adhesion between the layers occurs both through chemical curing and suction. So, adding a bit of water to the plaster mix for the second coat might be a viable option, as it can help it bond more effectively with the first coat—assuming the timing and conditions are right.
