I’m in the midst of a full kitchen remodel in a 1907 home that has beautiful fir flooring all throughout.  As part of the project I wanted to redo the kitchen floor so I rented a drum sander, got the old finish off, smoothed out a lot of divots and warping.  

Reading about how pure tung oil can be a good floor finish I decided to go that route.  I went to the hardware store and bought what I thought was pure tung oil from minwax.  I mixed it 1:1 with mineral spirits and did 4 coats over two days.  

I’m realizing now, two days later, that it was a tung oil ‘finish’ not pure tung oil, and I’m learning that it may not even have actual tung oil in it.  On the minwax website they even explicitly say it’s not recommended for floors.  I have a nice satin look and overall I like the appearance.  I’m just worried about durability and if I should put anything else over it.  It also caused the wood grain to raise a lot so I’m left with a rough feel.

Any thoughts to how I should proceed?  Hoping I haven’t just committed a huge sin and messed up my 114 year old floor.  Thanks for any input and advice!
