I had our red oak floors finished with Bona Nordic Seal. Our flooring guy used two coats of the Nordic Seal (3 turned the floors blue); two coats of a Bona satin sealer (I wanted matte all the way around, but I am pleased with the result) and a final coat with Bona Extra Matte sealer. I am super pleased with the result.
I think it’s great to see a professional looking for advice; don’t think anyone knows everything... that is the old school mentality!
