Temperatures and Marine Epoxy SK build in NC

Post by wannabatc » Fri Mar 03, 2017 10:11 pm

Well it has turned winter here in NC so I have decided not to glue anything until I got some feedback on temperature limits. I am building inside in my basement and my thermometer says it has been staying around 60 degrees but tonight it has dropped to 58. I bought both slow and medium gardeners because of the low blushing of the slow and the extra time to work fillets and fiberglass. I bought medium for when I wanted faster set up if I wanted to speed things along but also for colder temps. I'm just getting around to finding out the temperature limits. This my first build and I have little experience with fiberglass work.

What are the minimum temps I can work the slow hardener? And the medium? I have a small space heater and can use it if I have to but would rather avoid that if possible.

Thanks in advance for all you pt input.

I'm a bit south of you. Ive used slow exclusively (I have fast in a box that arrived from BBC so I won't be able to say that in a few more minutes).

I find that under 60F you need 24hr for it to "set" and about 48hr before you can sand at all. 50-60f you need have about 5days till sanding. Under 50f.. go inn vacation or find a heater (2weeks later it was tacky but warmed up and hardened overnight).

A few notes:
1. I'm on the coast so constant high humidity but that shouldnt factor.
2. Temps here swing wildly through the 30-50 range winter. A few of my observation times had big swings.
3. Karl (building ad14 here) showed a great way to provide heat in the cold. I will be stealing it soon.

It's cold this weekend and I'll be working with fast. I'll let you know how it comes out on my three (v12 Lil Bit).
