It's time to share some of my thoughts on natural floors with you.
Let's define it first. In majority of cases natural floor is a floor that has clear finish on it. The finish can be either oil or water-based. Each would have a different look over the time.
Water-based finish would make your floor very yellowy-pale, you would 'loose' the grain. I had a project in March, they hated their natural floor, so decided to use some Provincial stain.
Oil-based finish would have that traditional, old yellowy-orangy look. Not many people like.
On my last project they wanted to have a pure natural floor, that doesn't change the color over the time. The only solution was using the stain. Bona came up with Natural stain. Take a look at the pictures.
I'll upload some more pictures when I get a chance.
