How Often Do You Need to Varnish a Boat Deck

Image 0640: "Boat varnishing "

Marine varnish is a superb finish coating that is used to protect your wooden boat deck against sun, rain, wind, sea spray, UV rays, and chemicals. Varnishing products sold as marine or spar varnishes typically contain a mix of oil, solvent, resin, ultra-violet additives, and drying agents. At our South Florida yacht management company, we offer expert-level quality marine varnish to help protect your maritime vessel from the dangers of wear and tear. Our team of marine experts begins varnishing a boat by removing any old varnish, sanding the teak deck, and applying multiple coats of varnish until the service is flush, level, and looks excellent. 


The key to teak varnishing services is maintaining their upkeep. But how often do you need to varnish a boat deck?  Depending on the type of varnish used, you may have to varnish a boat deck every two to three years. Varnish finishes on timber that have been primed with CPES can last anywhere from 10 to 20 years with the proper maritime maintenance. 

The Secret to Varnishing a Boat: Oil Finish vs. Regular Varnish


Maritime finishes require regular upkeep and replacement. When varnishing a boat deck with an oil finish, boat owners can expect it to last a few months. With standard varnish on a boat deck, you can expect anywhere from two to three years before it needs to be re-varnished. For a long-lasting solution, we recommend using a combination of epoxy and varnish on a boat deck. 


Keep in mind that more coats of finish mean a more durable surface. Performing maintenance every year by applying coats of varnish or oil is imperative to the upkeep of every boat. Maintaining the finish frequently prevents damage and extra work and will make the wood on your boat shine like never before.
