I had an old oak floor that looked terrible. I assumed I would have to get the floor sanded and refinished. But after reading a lot Amazon reviews I decided to take a chance on Holloway House Quick Shine. I was blown away by the results! I did not sand the floor. I did clean it well before applying the finish. I may have used fine steel wool in some spots (I can't actually remember). The finish was very easy to apply with a mop. Best of all, the floor looked brand new when I was done. I did this 7 years ago and it still looks excellent. Read the Amazon reviews and watch some YouTube videos and see what you think.
