I need to refinish the old oak floor in our baby room. What recommendations do you have for a kid safe floor finish. I am leaning towards water based poly. Is there a better one though?

Some water based polys claim to be greener and safer than others but I do not know what empirical data there is to prove that and I don't know if making hte finish safer makes it less durable or not. I can tell you that Basic coatings and Bonakemi are two of the best manufacturers of water based coatings and you'd do well with products from either company.

Also, there is a "Finishing" section on the forum if you have any other finish questions about finishing floors.

Rubio Monocoat

I haven't worked with Rubio monocoat yet . I read that it is a one coat system and am wondering how the odor is ?

There is no odor Paul. Order some sample bottles and try it.

YUP Rubio Monocoat has a somewhat beeswax smell. But thats it. No V.O.C.

What do you mean by no odor? You don't need a mask to install it, or you can come back in a week and its safe.

Sounds good to me
