oki know the can says 70 or better but i got to get this floor finished for long point since we have what 28 days?

. if it is close witll it be ok just take longer to harden or will it really mess with the chemical bond of the glass. i would like to work on the floor tomarrow and they are saying a high between 68-72 here in stuart. should i stay or should i go for it

in my limited experience with resin it will take longer to harder in the cooler weather but will still be solid.

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.

I have used glass all the way down to 50 degrees, had to put a little more hardner in it (25% more), and it takes longer to kick, but it will. Epoxy is a different story, from about 45 degrees down, it WILL NOT harden until it warms up.

We've used epoxy with medium hardner & was told it's ok to about 65 degrees.

it works and it is solid got the wood down and layer of cloth on it so now is sanding and fairing and sanding and painting and then done. actually had a batch of resin get hard on me while i was working and got a lil warm in the container.

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.
