Today still used artisans varnishes in countries less developed economically, as happens in some countries in Africa. There fat and blood of cow are still used generally (although it can be any other animal) because also serves them to leverage resources available as livestock. Logically this resource is very basic and does not hold more than a few hours and every day needs another layer to keep the impermeability. With moisture that keeps a wooden boat is quite frequent to appear corrosion, fungi, or larvae that are installed, grow and are fed to the wooden base. For all this is strictly useful and necessary to a good treatment for wood, especially in boats that are used regularly and are facing greater wear. New techniques of treatment of the wood are not so basic as traditional, some treatments may be toxic or harmful to people and the environment. This is something to keep in mind, since the wood of ships is in permanent contact with the hydrosphere, i.e. water and all species and living beings that inhabit it, putting unnecessarily at risk the life of the biosphere of the place and can break the natural balance, if an appropriate wood treatment is not used.
Why all the treatments for wood must pass a series of conditions to demonstrate that they are not too harmful, toxic or harmful to health, because unfortunately many of the materials used can become highly polluting. However, we can today already find substitutes ecological and natural ancient and damaging varnishes. Although the ecological are a little more expensive it is worth worry a bit by the world that surrounds you, taking a little awareness and notion of acts that you perform and what they may trigger. One of these varnishes for yachts and boats is the exterior varnish, which is highly resistant to corrosion of the water and especially water marina, the Sun (to ultraviolet and infrared rays) and misting marina. Serves for any wood type, and location, with the exception of the submerged part of the ship’s hull. Fits perfectly to variations in volume by temperature changes, since it is quite flexible and resilient, as the scratches, shocks or atmospheric factors. If it’s a very sunny climate can be used oils and varnishes with uv-10 filters that are resistant to UV rays and much protect the outside and wood boats of many hours of Sun to which it may be exposed. Treating wood in time thus prevents wear and cracking. Although increasingly demand products to treat the wood of ships is less abundant, already are less frequent constructs wooden boats since their production is almost more expensive than other more resistant materials, that in addition to dispense with so many care like wood.
