I agree that Vermont Natural Coating is a very good product from the description. The end finish, however, I was told is a lot like Polyurethane finish. The floor does not breath, and it feels like resin, not wood. What other options do we have. I am thinking of children's wood blocks that are oil rubbed, and it is safe enough to lick. Are there anything like that for flooring?

We're just in the process of refinishing our wood floors, and I know what a pain it is to try to find a non-toxic wood finish! The only company I've come across so far that makes totally non-toxic finishes is one called Tried and True, which is the one we are going with. They make three different linseed oil (safe plant oil) based finishes that are food-grade safe, so you can use these on wooden countertops etc. We chose the one that seems like it will have the most durable finish when dry, called Varnish Oil. I've since read reviews on the internet from people who have used this finish, and they all recommend that it be applied in VERY THIN coats, i.e. with a rag and not a brush, as the brush will deposit too much product, and then it won't dry properly. Tried and True has it's own website with instructions on how to apply each type of finish, www.triedandtruewoodfinish.com.
