A pure or polymerized tung oil finish is easy to use and will produce beautiful results on any type of wood, inside or out.
Other types of existing finishes, such as varnish, must be removed, as tung oil is a penetrating oil. Exterior wood surfaces should be cleaned with water and a scrub brush to remove any residual stains or finishes. A couple of coats of Amazon teak oil makes this teak deck shine, but without making the surface smooth and slippery like varnish or Cetol would.
Back in the early ’90s, boaters had only a few choices when it came to protecting their exterior wood—traditional varnish, oils, or pigmented sealers.
Cetol Marine comes in a variety of colors, depending on the finished look and hues you’re going for. They don’t tend to protect for long, and the color varieties they come in are anything but natural or wood-like in their appearances.
Tung oil finishes are usually applied to unfinished wood, but they can be used over oil based stains.
This finish does not build a film like varnish, so you need to do most of the sanding before any tung oil finish is applied. Remove light scratches with a light sanding and the addition of another coat of tung oil finish. In our last blog entry about exterior marine wood finishes, we covered the basics regarding traditional varnishes.
That said, I have seen them used to nice effect on toe rails and other large pieces of exterior trim such as sportfish cockpit cap rails, which receive a lot of abrasive wear that varnish or Cetol might not stand up to.
They’re generally a concoction of linseed and tung oils mixed with UV stabilizers that protect the wood by keeping moisture out and minimizing sun damage. The way sealers work is by leaving behind a protective coating of solids on the wood after the carrier solvents evaporate away.
Proper prep, and then selecting the correct finish will have you well on your way to brightwork bliss. With Cetol, you prep the wood, and then apply a minimum of three coats, making sure you wait at least 24 hours between coats—that’s it. Cetol “Marine Gloss” can be applied as a topcoat on any of the aforementioned varieties to provide a shiny finish. That said, oils are great if you have only a few pieces of trim that you want to keep up, or for wood surfaces such as teak decks, where varnish or Cetol aren’t a good idea because of traction concerns.
