Our Watco Danish Oil is a penetrating oil, and should not be left on the surface, as this may result in a tacky finish. To apply our Danish Oil, apply it to the surface, and allow the oil 15 minutes to penetrate. Wipe the excess oil from the surface in the direction of the wood grain to ensure proper drying. Additional coats may be applied, however, the excess must always be wiped from the surface. - Rust-Oleum Product Support 2
