Lol that would be a problem. My furnace is in my basement, but it is in a different room with a door. So that might help with the problem of making the whole house smell. One more question though. How ventilated does it have to be? They aren't big windows. They are the small rectangular basement windows on most houses. Is it ok to just open them a crack? Because I'm afraid that if they are open all the way, it will get too cold in there. I live in MA and it's been 23 degrees F all day. If i only open them a crack and put a heater in the room, the resin should cure fine. But with the windows all the way open, the heater can only keep the room above 55 degrees for a short amount of time. I called the resin 1-800 number and they said 55 degrees was the lowest temp it can cure at.
