How much finish to mix?

[Billy 40]

I do my finishing in the basement and can tell you it varies greatly on ust how cold it is down there. I've been applying the epoxy at about 55 degrees now, and after 6-8 hours, I still cannot touch it. Niether the Supreme or Classic.

When it was about 45 degrees down there, it would take even longer than that (I'd say let it turn for at least 10-12 hours), and one time I made a mistake and shut the motor off after 6 hours, and brought the rod upstairs where it's about 70, and it saggied quite a bit.

Lately, I've been letting it turn for at least 8 hours (overnight), making sure it is slightly tacky (not wet where it comes off on your finger, rather you leave a teeny finger print). I'll then let it set up and harden in the warmer temperatures. To be honest, I'm really rolling the dice, but I've done about 40 coats of epoxt in teh past few months, so I've got it down.
