I found another question that sort of asks this, but the answers don't provide any detail.
We bought a 1918 house in somewhat rough shape. The second floor (with two bedrooms and a nursery when we're done with it) has (we're told original) pine floors that were treated years ago with some kind of polyurethane. Much of it is peeling (or has peeled) leaving exposed wood.
Treatment options I'm considering are polyurethane and Rubio Monocoat, which is a wax finish. The Rubio product claims 0% VOC, and comes with a number of stain colours. Multiple people we've talked to say that wax is the "better" choice for a century old pine floor, but can provide no concrete reasons as to why.
So my question is ... Why?
Is the amount of work and extra expense for a wax finish really worth it? What does a wax finish get me that I'd lose out on with polyurethane?
And finally... Has anyone got an opinion of Rubio Monocoat? Aside from the colour options, is it really that much better than basic tung or linseed oil?
I realize that if I sand things down and apply poly, there's no going back. I just don't think I know enough to make the right decision.
