We just bought a house with American chestnut floors but the original owner never sealed or finished them. My husband and I would like to properly finish the floors but don’t want to affect the intended look. I found this photo and like how yours turned out. Did you use the Minwax 3 step process to finish them? Did you use oil or water based? Did you use the pre stain wood conditioner? Did you add a polyurethane top coat? Any details you could provide would be great appreciated!
