and maybe put a fan in the window blowing out to push the fumes out of the basement and the house. I put up a poly wall, with the fan in the window, it really helped. I even varnished in there... the fumes inside the polyied area could knock you over. on the other side of the barrrier, you could just smell it a bit when you first came down stairs.

Varnish is worse than Epoxy for the fumes, you might consider leaving that to next spring and do it outside.
