By Second coat do you mean, the second coat of finsh or the finish on to the base coat(bonding, browning, hardwall etc..)
I apply second coat of finish on to finish straight away, after you have applied first coat, and starting back at the point you started to applying this coat and mixed up the second coat, a period of time has elapsed anyway.
If first coat of finish, on to base a couple of hours.

Second coat of Multi should go on straight after the first as soon as it will accept it. There is no set time, 1st coat needs to be just slightly firm to avoid pulling it over with the 2nd.
2nd base coat or finish skim over base should be left until it's cured, usually from around 1 1/2 hours.
1st & 2nd finish coats should be part of the same mix unless you have someone mixing for you. If you have to stop to clean down & mix afresh, you’ll almost certainly run out of time on all but the smallest of jobs as many new to it find.

so basically you are saying as soon as my first skim coat has gone on make another mix and apply the second coat strait away.

I like to have my second coat slightly wetter than the first, I either prepare another mix or water down the remainder.
This is generally for small DIY jobs rather than large areas.

Richard C is right about best in 1 mix. However, still learning myself and only on the smallest walls have I managed in 1 mix.
Therefore I've done a fresh mix for the second coat and been ok.
Have found it's given me much more time to get a better final result.
As DIY only, this is prob ok.
