Assuming you want to protect and embellish your boat exterior brightwork, how do you choose among the astounding variety of products? Recognizing completely that this is as big a deal as debating the differences of motor yachts vs.pandora, sailboats, we nevertheless offer the accompanying observations.

What is a Varnish

A varnish is a liquid coating commonly applied to treat wood. Its principal ingredients are Wood Oils. resins, solvents, dryers and ultra-violet additives. The elements are mixed in different quantities to provide the best appearance and protection.

Oils

Oils generally hold the new look and grain of the wood to a greater extent than the other finishes because they permeate deep into the wood fibers and do not produce as much of a surface coating. Oils are available in colors ranging from water clear to gold to dark brown. As with any teak finish, multiple coats generally result in a more uniform finish and greater length of service. We learn oil to be the easiest to apply, since surface defects are not as obvious in the ultimate outcome. This doesn't mean, that applying four coats of oil on raw teak will develop a Bristol finish. You will also find that oil light consistency makes masking areas to protect surrounding gel coat and painted surfaces about as important with oil as with varnish. Clean, sanded teak with 3 or 4 coats of oil can provide 3-6 months of protection and beauty.

Tung oil is one of the most widely used for teak applications.

Spar Varnish

Spar or marine varnish is a refined product consisting of oil, solvents and thinners, resins, dryers and additives. By varying the proportions of the elements and by blending UV inhibitors and different secret ingredients, manufacturers create varnishes with widely varied features. Varnishes can have a high gloss or matte appearance, can be formulated to be extremely hard for walked-on surfaces and can vary in color.

The 2 most routine varieties of varnishes are natural resin varnishes such as tung oil and oil-modified polyurethane varnishes. Natural tung oil varnishes are great for marine use and offer the traditional golden look. Polyurethanes tend to be more clear, allowing the color of the wood to shine through.

Newer varnishes, furnish better durability in the harshest of environments such as the hot, tropical sunlight. Teak moves, since it is a formerly living plant, it expands and contracts with even small fluctuations in temperature and humidity. Premium varnishes contend with this unstable material employing high quality Oils and resins and a greater percentage of solid ingredients, providing a longer lasting, more elastic finish with a greater gloss.

Six to ten coats is usually necessary to get a quality look. A good base, annually cared-for with maintenance coats, will give the ultimate in appearance, length of service and protection. Despite the initial effort (up to 10 coats are common) nothing appears better than exterior brightwork finished with gloss varnish.

Interlux Original 90 is just one variety of traditional spar varnishes on the market.

Synthetic Teak Finishes

These coatings gained popularity with cruisers in Florida and the Bahamas searching for ultra-violet resistant low-maintenance exterior teak. Developed for ease and speed, these products have uncommon durability for outside use, are easy to apply and look comparatively good. I say comparatively good because some of these finishes, have a pigmented appearance, sometimes with an orange tint. You must be careful not to apply too many coats. Some varnishes such as Interlux Goldspar and Schooner are produced with no pigment so the wood beauty is saved. Full gloss and depth vs. convenience is the trade-off with these finishes, but simplicity and labor savings can more than compensate. Ease of application is similar to teak oil, where you can apply it immediately over sanded, clean teak. I know of one professional that uses Cetol exclusively and his work is fabulous.

Cetol comes in four forms, with the new Natural allowing for a more golden color like the real appearance of raw teak. You can overcoat any of the other pigmented Cetol products with the Gloss for a shiny exterior finish.

Two Part Wood Urethane Finishes

Another product to show up in the cruising world are the urethane two-part products. Fashioned to replace traditional varnishes, these products have made a mark in the yachting community. Their producers developed these finishes to survive in tropical environments for years at the time. One maker, C Tech Marine, boasts that its product Bristol Finish is utilized on numerous cruise ships, attesting to its beauty and longevity.
