Minwax "Polyshades" -- why not for floors?

Same!! How did it turn out? By sanded, do you mean you took it down to the bare wood? Or just scuffed with a buffer?

Wow I did my floor with the blue poly shades and it is beautiful!

It is beautiful until it wears off. It is not a penetrating stain - more like a "toner" and it doesn't wear terribly well.

I moved to Manhattan in 1995 to an old apartment with dry wooden floors that had not been refinished in years. I would say there was more color than finish on them, no shine at all. A friend from New Orleans said he used Minwax Polyshades right on top of his old floors with amazing results. Since it was a small space and I could redo them if it didn’t work, I tried it with fantastic results. I lightly sanded the medium-brown floors and hand l-brushed old maple polyshades right on top of them to make the color richer. I was in the apartment for 14 years and had no problems. While I would not do this to new or completely re-sanded floors as a base finish, it definitely worked as a facelift for old floors as a top coat.
