Epoxy cure question

Builder's Forum

I am doing the rub rail scarf joints for the Chester Yawl.  CLC manual says 24 hrs. at 75 degrees.

Since my basement is 60 or so, I hung lights over the joints bringing the temp. to 75-80.  These will be on for 8 hrs.

My questuion is if I turn off the lights overnight and joints cool to 60 room temp,, should I turn them on again in the morning  or just finish the cure at 60 degrees?

If I leave them at 60, roughly how much more time will it take for the cure?

Thanks for any help.

You will find that if your work area is low humity and a stable temp of 64+

degrees your cure will be fine.  I am building now in an area of that temp and it is cure to tough within 8 hrs and I let it cure 36 hrs before I sand and recoat.
