Norwegian saturation oil for treating wood inside or out. Pronounced “Decks Olya”. The finish is applied wet on wet until the timber is saturated. It goes into the timber rather than sitting on the surface. Leaves a silken oiled look. Can be overcoated with D2 to provide a gloss finish. Thinners: Do not thin. Coverage approx for D1 is 1 L / 0.75 - 1 m2 . Coverage approx for D 2 is 1 L / 15 m2 .
