Unique blend of penetrating oil and varnish hardens in the wood, not on the wood. Watco Danish Oil penetrates deep into wood pores to protect from within and to enhance the natural look and feel of the wood. It creates the rich, warm glow of a traditional hand-rubbed finish. Indoor use only (Not recommended for Floors). Stain, seals, and protects in one easy step. Will not crack, chip, or peel.
