I've been reading most of the posts and it seems that you's put your first coat on, wait a bit then mix new plaster and put the second coat on. This sounds like a good way of doing it as I've been taught to mix one batch, use 2/3 for your first coat and then go straight over with the remaining plaster as soon as poss. This does work and gives a good finish but it means that I'm limited as to how far I can get with a mix and have to split walls up into sections and join in. I'm wary of doing it a different method as I'm new to the game and I can judge my timings well the way i'm currently doing it but want to cover more.
