Kevin Stricker said:I wouldn't consider Waterlox if you have kids unless you all are going on vacation for a couple weeks. For hardwood floors you are going to want 4-5 coats, which will take at least a couple weeks to even a month to off-gass. As previously mentioned Waterlox is a pretty high VOC finish. If you don't want to go the Poly route maybe consider a hard wax finish.
This isn't a house that we live in... so there's no concern about VOCs (also, I don't think that anyone will sell the non-VOC compliant version of it to me, as i live in California).
