I am a homeowner who recently had the floors in two bedrooms refinished in a 1940s home in CA. The floors are oak. The floors were supposed to match the rest of the house, which has a finish that is 20 years old and surprisingly in relatively good shape. The finish on the older sections of the house is a light yellowish color, with still a relatively good sheen. The recently refinished floors were done with a water-based finish (BonaVivia - I believe - not sure of spelling). They are not light like the existing floors, nor do they have any sheen. Any suggestions? I have been told that preparing the wood with two glaze coats and then a water based finish will achieve the same look as the existing floors, but I have already read that oil-based finishes have an orange tint so I am not sure if this "glaze" process will result in orange-ish floors. The floors in the older sections of the house are not at all orange, if anything I would describe them as light yellow.

They could have used a water base sealer called Bona AmberSeal on the first coat, which gives the look of an oil base finish. Since the floors are already finished you might try installing some small transition piece at the door way entrance ways. This will give a break between the 2 floors and it will not look as odd. hope this helps

Should not have use water based finish if you were trying to match an oil based floor. Sheen's are completely different. Colors are completley different
