Hello, We had a three season porch re-done in the Fall. Last step was refinishing the floors (that had been refinished once before by the way). We agreed to do a regular polyurethane because the area will be highly trafficked from outside and potential for water from windows. The room is lovely. However, we have not been able to use it because of a strong polyurethane smell. The room does not have heat, and it was cold when this was done, so probably never cured. After running fans and having all windows open - the windows are huge and cover 3 walls - I finally gave up and hired another contractor to sand floors and apply a water based poly. Not that much to fix it this way and gave up on first floor guy.

Soooooooooo, 2.5 weeks later and there is still a strong poly smell. We used the same water based poly in our kitchen and no smell there after a few days. Is it possible that the first poly seeped into the floor boards? There are those little gaps in the flooring. Underneath the floor is spray insulation, regular insulation and plywood, so it is sealed up tight underneath.

Any suggested remedies? I am at the point where I am ready to have the whole floor ripped out. I've read posts about the residual smell, but there never seems to be a final remedy. I appreciate any thoughts or suggestions you may have. Thank you.
