: Building a Yost Sea Tour 15 EXP. Epoxied the chines and gunwales to
: the cross sections, but due to an unexpected turn of the weather
: and a failure of the heating system in the building shop, the
: Epoxy (locktite brand 1 hour pot life ) was exposed to mid to
: high 40 degree temperatures over night. Needless to say the
: epoxy did NOT set up, and though it is not still runny it is
: pretty close to dried rubber cement, you can press your
: fingernail into it and it will peel easily. Is there any chance
: these joints will continue to set up if I can get it into a
: heated environment?

Hi Dan,
It sounds like the ratio of resin and hardener may have been off slightly. This will usually produce a rubbery consistency. It could also be the actual mixing was not thorough enough. Locktite brand is sensitive to temperature but not as much as marine epoxy like Mas or RAKA or West. Even that, 40 degree will slow but not stop the set.

You could go ahead and lash the joints in question. This will reinforce the joint sufficiently.
Good luck with it,
Clayton Plunkett
