Hi, I live in Sweden and Im renovating a glass fibre boat. I bought EL2 laminating epoxy to use for reparations of different sorts. My problem has to do with temperatures, I intend to do the job during winter when the temperature at best is in the region of 5 degrees above freezing. Even if I wait until spring, longer periods of temperatures in the 15-20 degree range are not likely. In other words I need to use external heating regardless. This is a problem in itself, it can be hard to control the exact temp. but more importantly, I'm not allowed to leave heating equipment unattended. In other words I need to babysit the heating equipment while it is on.

-Ideally Id like to raise the curing temperature and reduce the curing time. Im not necessarily after maximum mechanical performance. How high can I aim to go and what would the resulting curing time be? (at the moment Im afraid I only have the slow hardener)

-I did the misstake of ordering the "slow" hardener. Would I gain from ordering the fast one?

- I intended to mix the components cold, apply them and then apply the curing heat. Ive understood from other threads that the components should have the correct temperature during mixing, is this really crucial?

-Air humidity is crucial for paint application, is a relative humidity of 80% considered maximum for epoxy work as well or what do you recommend?

-I have areas with damaged sandwich material where I intend to inject resin. Id like to use epoxy resin with added milled carbon fibre and intend to do some testing before hand to find the mix ratio. Which weight percentage would you recommend me to start of with?
