Ding repair in low temps

Hey all friendly people. Got no clue about resin and temperatures. Doing well with repairs in the summer heat, got whitepapers. But in a few months, when winter comes, and it get’s freezing here, i expect my basement to be as cold as 8(C)/46(F) somedays. Can I still work with the stuff? How do I mix the resin? Does it get weak, is it enough to heat up the resin and ding with lights (got a big 300w among others) while working? If you got a table showing mixing ratios/temperature, that would be great. Searched the net but no words about temp’s as low as these. Thanks /Joe
