Will resin cure in 40 degrees?

Because the epoxy will probably go dormant below 35-40°F, but will begin to cure again once the temperature rises. Electric hot air guns and/or electric blankets designed for concrete can be used to provide temporary warmth to a cold substrate. Take care to avoid heating the surface or any standard epoxy to over 200°F.
