Deks Olje is a two step wood finishing system that is much easier to apply and maintain than traditional varnish. D1 is applied first. Deks Olje D1 is a specially formulated penetrating oil that soaks deep into teak and other marine wood grain, producing a rich transparent matte finish. The oil helps strengthen wood against the deteriorating effects of sun, salt, wind, and foot traffic for increased durability. If you desire a matte finish similar to rubbed Tung oil, D1 is the only step necessary. If you wish to continue to a high gloss finish, apply D2 over the D1. Deks Olje D2 is very easy to apply, and produces a hard, flexible gloss coating that doesn't chip or peel like varnish. Fully cured, D2 is slightly softer than traditional varnish but very easily maintained. You may blend seamless touchups to high wear areas with D2.
