This is a deck constructed of Port Orford Cedar. Port orford cedar is the hardest of all the cedars. This deck has a light brown penetrating oil on it. Because cedar naturally has a high amount of resins in the wood it takes a few years before the oil will actually penetrate in as it should. Cedar decks should remain unfinished for a year before putting a penetrating oil on, especially port orford cedar. This wood needs an experienced wood guru like myself to take care of it.
