Bubbles in your curing epoxy can be nearly eliminated by warming your canoe work space to 73’ prior to glassing. As you glass the canoe and through the day, allow the temp to drop ever so slightly. By the end of your glassing day, the space in the room should be about 67’ and then remain at least that temp over the next several days as the epoxy cures. You will find the the issue with bubbles is almost eliminated. The temperatures I mention do not need to be exact but are your best case example. Epoxy curing times are directly related to air temp. Those are the temps I use when glassing and they work very well and for figuring epoxy cure times by most epoxy formulations. Cooler temps= slower epoxy curing. Keep in mind that a great deal of heat is generated by the mixed epoxy in your mixing pot over a short amount of time. Getting it out of the pot and onto the canoe as soon as reasonably possible is very important. Tom |

Yes, a torch will work. Remember they are pouring, a table top epoxy. You are using a laminating epoxy, for a canoe or kayak, with a much short pot life, |
