temp and resin

[Entourage]

Question for this subject, i was doing my floor today in my sceptre on cape cod and the temp was about 39 and the sun was beating on me. I was using hull and deck putty and it seems like it was taking a while to dry. Was this because of the cooler temp? It is no Stuart up here, you guys make me jealous.

the cure cycle of your standard epoxy is a time vs temp curve... the cooler the temp, the longer you wait. polyester is a little different in that you can accelerate it with mekp...up to a point and then you start to ruin your resin properties. my bottles show me a range of mekp for varies temps. but I've been laminating in my garage all winter at about 30, maybe colder, no problem. I just throw a plastic sheet over everything and little space heater makes a nice 'oven': the key is to use a thin plastic (5mil) so the hot air blows it up some.
