I am considering purchasing a kit now but am wondering if I can build it in my garage in the winter in Minnesota. Do I need to heat the garage while curing the fiberglass or am okay working in the colder space? If anyone has any insight on this I would appreciate it.
I’d recommend a space heater and thermometer for your garage. The epoxy that came with my kit was MAS LV w/ Slow Hardener.
look here for the manufactures FAQ https://masepoxies.com/faq/
Pay close attention to the MAS epoxy cure schedule on the FAQ, they do not recommend using the product in temperatures below 41°F and for every 18°F the temperature falls below 77°F, the pot life will double for the mixture.
I live in Indiana and I started my build in march when it was still cold. my workshop (20′ x 20′) has a ceiling-mounted Dayton electric space heater (5000 watts, and 220 volts) and a wall-mounted line voltage thermostat.
the resin and hardener are really viscous below about 65F. I started out with the shop heated to about 60F and I kept the resin and epoxy in the house so they would flow better out of the pumps. however, once the epoxy was mixed and spread on the cold surfaces that I was fiberglassing, it became more viscous and a bit harder to spread.
after a few days of that drill, I raised the temp in the shop to 70 a few hours before I started a work session, and then lowered it to 60 when I was done for the day.
I’m afraid that working in the winter in a minimally-heated space won’t work for you.
I live in MN and plan to finish my epoxy in the Spring. I am opening a DIY studio – so I had to postpone the finish until 2018. If you don’t have a heated space – I would wait to epoxy until it gets warmer.
