Yacht varnish for wood - what are its advantages and how to use it correctly

Yacht varnish for wood - what are its advantages and how to use it correctly Yacht varnish: application, characteristics , advantages and disadvantages. When it comes to all types of wood finishes, yacht varnish is considered one of the most durable, wear resistant, and also the most preferred.

Initially, they covered the hull, as well as the details of the equipment of wooden sailboats, yachts (hence the name), boats to provide and moisture repellency, to protect the material from mud exposure, sun, wind and premature destruction

Chemical composition and properties of paintwork materials

Yacht varnish for wood - what are its advantages and how to use it correctly Name "yacht "or" yacht "," deck "and" ship "in relation to the varnish composition has become an indicator of a high level of practicality, and is also used by a large number of manufacturers even as a marketing ploy.

The popularity of such finishing has increased, and the point is not even that buyers began to massively acquire water sailing vehicles, but the use of this type of coating for repair work inside apartments and houses. The performance of a yacht varnish can be considered an order of magnitude higher than that of traditional products that are designed to cover furniture, floors and even doors.

In general, these types of paints and varnishes are more resistant to moisture, elastic, stronger, and able to withstand large temperature drops. But, when choosing them for coating indoor surfaces, one should remember one very huge drawback - a very high level of toxicity.

Yacht varnishes, due to the fact that they were not originally intended for domestic needs, in addition to organic resins, contain very toxic chemical compounds as solvents - xylene and toluene. Substances during work and after application evaporate very quickly and easily. When the work is carried out, toluene begins to decompose into hydrogen and carbon, and causes severe irritation of the mucous membrane of the eyes, as well as of the respiratory system, sharp headaches, lacrimation and even nausea.

But xylene can even penetrate into the human body not only through the respiratory tract, but even through the skin.

Toxic fumes will occur for a certain period of time after the surface is completely dry.

This poisonous element, when accumulated, begins to cause diseases of internal organs and dysfunctions of the nervous system. It is for this reason that during the work it is worth providing full ventilation, and such varnish cannot be used to cover furniture in the bedroom, children's room, or even in the kitchen, and it is also not suitable for large areas in the house where there is no good ventilation.


Depending on the base used, you can count several types of yacht varnish, which

will differ in performance characteristics:

  1. Alkyd.

    Due to its low cost, it is one of the most popular, but far from the safest. It contains benzene compounds, white spirit, toluene in large quantities, as well as a pungent and difficult smell. Throughout the entire period of application of the coating, their surface will constantly evaporate chemicals into the air, and therefore such a varnish composition can only be used for external work - covering roofs, wooden fences and gazebos. The service life is approximately 5 years, provided that the load is moderate mechanical.

  2. Yacht varnish for wood - what are its advantages and how to use it correctly Alkyd-urethane .

    It has qualities that are similar to the previous material, dries quickly, it contains special plasticizers, and it is suitable for processing soft wood. It is very toxic, therefore, such a yacht varnish can be used only for outdoor work.

  3. Urethane - alkyd . It contains a greater amount of urethane compounds, which will prevent the rapid evaporation of volatile toxins, and therefore it will be less hazardous to human health. The material is quite resistant to temperature extremes and plastic.

    This type of deck varnish works very well for indoor flooring and can be used for a heated floor system because the varnish will not crack. The service life is up to 10 years.

  4. Acrylate . This type of varnish is less toxic and consists of water-soluble components, so the material is perfect even for interior work. Among the shortcomings, it is worth highlighting the rather high cost of work and low resistance to moisture.

    It is impossible to cover the hull of the boat with such a varnish, because in this case the marking "yacht" from the manufacturers refers only to high quality indicators only for marketing.

Semi-gloss, glossy and matte varnishes can also be distinguished by the degree of gloss. The use of the latter is more reasonable if you plan to process huge floor areas in a bright room or technical buildings.

Moreover, dust, defects and small cracks are not so much visible on a matte surface, and gloss is able to emphasize all imperfections and irregularities, and is suitable only for decorative finishing or floor covering in a darkened and small area room. Otherwise, the choice will depend only on taste.

Specifications will not be affected by the reflectivity of materials. The assortment of most manufacturers includes pigmented paints and varnishes for buyers who prefer color tinting.

Carrying out painting work

Before applying the varnish composition to the floor or other surfaces, fresh boards should be thoroughly cleaned, sanded, swept away debris.Before starting work, stir the liquid, bring it to homogeneity, and, if necessary, dilute with white spirit or another solvent that is ideal for the varnish.

The coating should be applied with a roller, brush or special paint sprayer.

Work should be done only at positive air temperatures in the atmosphere - from 15 to 30 degrees and an average level of humidity. In this case, it is imperative to protect the hands and respiratory organs. For outdoor processing of wood, you should choose warm, but not at all hot weather, and there should be no strong wind and precipitation.

When the wood surface has been cleaned, it should be treated with 20% diluted varnish or other suitable primer. When the bottom layer is dry, the material should be sanded again with fine abrasive paper and any identified roughness should be removed, and then apply a new layer of undiluted varnish.

Depending on how dense your finish is, two or even three coats may be required. If the wood was previously varnished, then the old coating should be cleaned off only when it is cracked. And if you just need to update everything, then first try the department on an inconspicuous small area.

If, within a few days after drying, the varnish did not begin to peel and swell, then it will be possible to cover the entire surface with it in a couple of layers, and each next one can be applied only after the lower one dries. The drying time of the material will be approximately 4 to 8 hours.

Sanding with an abrasive can be carried out between applications for durability.

Consumption of deck varnish per square meter is approximately 0.1 kg. For successful drying, it is required to protect the surface from direct sunlight, heating with electrical appliances and moisture. The coating will fully harden in 4 to 7 days.

The remnants of the material must never be stored in frost or near heating devices, and must not be poured down the drain.

Advantages and disadvantages

The characteristics of yacht varnish are incredible, and therefore the advantages of this material are also enough:

  1. Excellent adhesion to wood. It has a high degree of adhesion to surface materials. The varnish instantly impregnates the material, remains in the structure of the wood for a long time and acts for a long time.
  2. Not affected by the harmful effects of ultraviolet radiation.

    The sun is practically unable to have a harmful effect on the material that is covered with deck varnish, because it contains special components that absorb radiation. Also in the composition there are light stabilizers, which are able to convert ultraviolet rays into heat, which will help keep the protective film intact.

  3. Makes the surface beautiful. The decorative component will also play a huge role in drawing attention to the product. Such a coating will look well-groomed.

  4. Hydrophobicity. This product helps to increase the resistance of wood to moisture, as well as get rid of the damaging effects of rot, the formation of mold / mildew that destroys the wood.
  5. Resistance to wear. The film is capable of ensuring the durability and resistance of the material to mechanical stress, and at the same time the coating will be protected from the appearance of chips and scratches.
  6. Resistance to chemical influences.

    No reaction with alkalis, acids and salts. This makes it possible, if necessary, to wipe the surface using household chemicals.

  7. Elasticity. The varnished surface can bend without much damage to the film, and it will not crack.
  8. Relatively low cost.

    Availability of purchase is another advantage of deck varnish over other properties. Saving money makes these products in demand among many buyers.

And if we talk about shortcomings, then yacht varnish is fragile in the cold, since it is not able to withstand low temperatures - this begins to change the properties of the material. Moreover, it is hazardous to health.

In order to improve the use of such materials, most manufacturing companies have started to include various components, and the problem is toxicity.

Yes, as mentioned earlier, toluene and xylene are substances from the benzene group, and their poisonous vapors enter the human body quickly through the skin and breath.

Manufacturers, prices

When choosing a deck varnish for finishing the floor surface and other wood surfaces, one should take into account such parameters of the paint and varnish composition as resistance to moisture, abrasion, temperature extremes, mechanical stress, elasticity, decorative qualities and toxicity.

It should be remembered that this type of coating is inferior in strength to conventional varnish compositions for covering parquet floors, although it surpasses the latter in terms of water-repellency.
