Cold weather causes all coatings to cure slower. The fact that your friends job bubbled and peeled was prob not a result of cold temps but of inadequate surface prep (not scuffing enough and maybe not cleaning well after scuffing)
I would not push anything to be applied as low as mid to upper 30's. You really need to be upper 40's at least to avoid curing issues. Low humidity and low temps when applying moisture cure type coatings like Herc could cause it to not cure fully and stay that way.
Do yourself a favor and try to get a heated space to work or wait till spring. Avoid using any heaters with a flame if you going to work with Herc which has flammable solvents
