Refinishing an old shellac floor
I need some advice and after looking through a lot of old posts, I still need some help.
I am trying to refinish some red oak floors that are 50+ yrs old. They spent a long time under carpet and have some trouble spots, like dark splotches, areas without any finish, cupped boards, etc... I have learned that they are shellac and I don't think they have any layers of wax on them. I am wondering if they have some sort of stain because in some spots that I had to repair and sand down to new wood, when I brushed on 2 coats of Zinzer Amber shellac it doesn't quite match. Could that just be the age of the wood and not a stain?
Some more questions and info. The front two rooms had been previously refinished with Polyurethane and the color matches great where the two finishes meet. Would I be better off just using a drum sander (I think I would have to sand too long with a random orbital because of the cupped boards) and matching the front rooms? The Dark spots in the finish are kind of like scabs, I can use a putty knife to scrape some of it off but they go completely through the finish to the bare wood and I can only get them out by dabbing Denatured Alcohol on the spot, letting it soak in, and then wiping it vigorously. This of course leaves a ring of unfinished wood that I have tried to brush over to make it disappear, but cannot seem to make it blend in.
Also, I have been trying to find amber shellac in gallons but no one seems to carry it. Would I be better off mixing my own shellac (sources anyone?)? What did they do back in the 50's? What kind of advice do you have for application?
I know it's a lot but I feel overwhelmed right now...
