Epoxy question - ambiant temperature

I am trying epoxy resin for the first time (Resin Research) but am concerned that it may be too cold. The weather forecast for tomorrow is about 60 degrees. I have the “slow” hardener. Am I asking for trouble? Should I wait for warmer weather?

Heat lamp, turn on lights, aim for 65 degrees and it’s fine.

Lotsa time to flip/saturate laps.

Most guys first lam, takes over 30 minutes for a decent job, so you have it.

Hey RandR,

There have been posts using it in as low as 40f but I think that’s would be its extreme. You should be fine - just be patient as it’s probably going to take most of the day to harden - maybe more? If using a heat source, be careful directing it right at the what your curing. I’ve gotten some bubbles, sags etc in the past.

If you go forward, would you keep a log of the times/temps for us and report back?

Best,

Herb

Using some cabosil to thicken it up seems to help in my drafty old garage.

I got a shop light going as a heat source and was able to get the temp up to 65 degrees. Worked out OK. Got the bottom lam done. Did it about noon today. Just checked it and it’s about ready for the top lam. Will get that done tomorrow.

Thanks!

be sure your temp is right when doing the deck and sanding coats. epoxy doesn’t stick too well to anything (including itself) at lower than ideal temperatures. it will go off okay and appear to be adhering, but one sharp rap and it’ll separate from itself. believe me, you don’t want that to happen. been there, it’s a total hellish nightmare…

surfthis - What would you consider to be a “right” or “ideal” temp? Certainly wouldn’t want to have to redo the deck and sanding coats!

Sorry for the delayed response, I believe you should be fine above 50 degrees F. Check with the guys at RR they should be able to tell you better than me. I found out the hard way during a cold snap.
