Most yacht owners adore a beautifully varnished mahogany railing or hatch cover. Sailing yacht varnishing or gulets with no exterior varnish might have at least have, door frames, bookshelves and mast supports varnished inside or outside, needs regular maintenance and revarnishing to stay in top-notch condition.
Yacht varnishing is to improve two important things, they enhance the natural beauty of the wood and protect it from the weather and seawater damages. One of the most harmful threats to wood varnish is ultraviolet sunlight. Even though all exterior yacht varnishing should be ultraviolet proof, all final finishes of varnish will break down when continuously exposed to bright sunlight and sea spray.
As the sunlight penetrates the yacht varnish, removes the varnish from the wood. You must have seen a teak toe rail whose wood color is turning black under a smooth exterior. Because the varnish is no longer sticking to the wood, it must be completely removed and replaced with several layers of varnish to restore the glossy finish and provide the expected protection for the wood.
The most important part of yacht varnishing is the time you spend applying it, so a cheap varnish may not be such a good idea. It is worth spending extra money for a good quality varnish so that having the final glossy finish lasts as long as possible.
