I am restoring a 1920's Craftsman home and am having an issue with my
flooring refinishers. Here's the scoop...

The upstairs floors are pine, 75% of the flooring was in great shape
and 25% had to be replaced with new planks. After the planks were
replaced we had the entire area sanded. We asked the flooring
refinishers to try to match the natural ambering in the original wood -
theoretically with Shellac - as the original floors had no stain and
just Shellac on them. Instead, they have put 2 coats of polyurethane
on them and are coming back to do a third coat Friday.

What we have ended up with is a room that has a bit of ambering in the
old sanded wood, light blonde new pine and a plasticky gloss
polyurethane finish. In short, it looks awful.

The flooring company is saying that they told us they were putting on
poly and no stain so will only offer a 10 cent a foot discount for
re-sanding and re-finishing.

I've been searching online to see if anyone has used Shellac over
polyurethane and can't find any info. I am hoping we can just put on a
couple coats of Shellac without sanding, let it cure and then wax the
floors--any suggestions are greatly appreciated.
