Varnish for wood - the beauty of the material in safe hands !

varnish for wood - which to him are requirements?

Essentially, lacquer - a solution of substances capable of forming on the treated surface of the protective layer into a thin film.It would seem, what choice is all about?You can take any varnish and "protect" the wood.However, all is not so simple, because the varnished wood, which is picked up incorrectly, can do more harm than good.Only after taking into account all the nuances you can talk about the selection of really good varnish.So, the main selection criteria include:

• Durability.The commercially available lacquers, characterized by an increased resistance to wear and tear indicator.Typically, they are used to protect flooring suffering from the large load of friction and constant distance.If the additional wear protection you do not need, you can choose an ordinary composition.
• complete drying time.There is a choice between the traditional compositions, the drying time can reach 30 hours, and their alternative - quick-drying varnishes, allowing to cope with the job for one night.The highest point in time drying water-based, and the smallest - in nitrovarnishes.
• toxicity.Most of the available on the market today lacquers (polyester, acrylic, polyurethane) differ unpleasant pungent odor, due to the content of solvents.When used in a residential area, you risk to amass a headache for a few days.In this case, preferred is a varnish for wood odorless, for example, water-based.
• degree of gloss.You can purchase a composition, which gives the wood surface a nice looking glossy shine, or to make it matte.When choosing a recommended follow their own preferences and the degree of gloss on the surrounding surfaces.
• Fire.Selected varnishes for wood and depending on whether the surface being treated is exposed to high temperatures.If wood is used in a room where there is a risk of fire, it is necessary to acquire a heat-resistant coating, which does not support combustion.
• number of basic components.Today they say about one- and two-component lacquers.In the first case, the protective film is formed by solvent evaporation and complete drying of the residue.The second - the film is the result of chemical reactions between the solvent and hardener.Such two-component paints are called professional, as they provide the highest quality protective film.

On top, it is recommended to pay attention to whether the varnish is applied directly to the timber (Self-priming) or it requires additional processing.This is not the main criterion for the choice of composition, as in the sale of the most frequent is the first option, but you can not ignore it.Considerable importance is the quality of the wood, the degree of porosity, for example.This is important since the nail is not suitable for pine and birch processing etc.Moreover, the quality of wood is directly related to indicators such as consumption of wood varnish.

varnish for wood for exterior and interior - what is the difference?

The impact of external factors - it is one of the main criteria for selecting varnish.So, if the product is made of wood or wood surface is located outdoors and exposed to all weather conditions, UV rays, it is recommended to buy paint for the exterior.That it allows the wood to withstand numerous wetting-drying cycles of freezing and thawing.Using the varnish, in this case for interior works lead to rapid crack timber abrasion and yellowing of its surface.

Experts note that the varnish on wood for outdoor use should be mandatory to include in the composition of the substance providing surface protection against UV rays and prevents the formation of mold on it!

distinctive feature of these compositions is the high degree of elasticity of the protective film that allows it to not break when an admissible deformation of wood.Unlike varnish works external character composition for internal work to be less elastic.The formed film must be characterized by their high degree of hardness and strength.Thus, competent selection of varnish, depending on the intensity of external factors directly affect the durability and aesthetics of a wooden surface.

Varnish for wooden floors, walls, furniture and other surfaces - choose the composition

One of the main criteria is the composition of the varnish, which determines its performance characteristics and features.The main types of varnish for wood for today: alkyd, alkyd-urethane, oil, acrylic, epoxy, polyurethane and nitrovarnishes.Each species has its advantages and disadvantages.The most widely alkyd formulations which are based on organic solvents and alkyd resins.

They are perfect for interior applications, are able to withstand exposure to moisture to form a durable and reliable coverage. major shortcoming is the only time of drying, reaching 72 hours! reduce its hardeners allow additive, but in this case need to fully dry day.By adding to the alkyd resin urethane groups obtained urethane alkyd varnish, alkyd characterized by high resistance to wear and less drying time - about 6-12 hours.

Oil varnishes are also suitable for interior applications, in particular for primary processing of wood and giving it a particular hue.The color palette is quite wide - from light yellow to deep brown.Depending on the amount of oil to speak of fat (65-85%), the average fat content (55-65%) and lean (30-55%) formulations.Fatty varnishes perform both functions - a protective and decorative, but the skinny are good only to make the wood aesthetics.

include nitrovarnishes (nitrocellulose) to the category of quick-drying on the right.For their complete drying must be only a few hours.Moreover, they can easily penetrate into the pores of the wood, filling them completely and providing excellent surface protection.Nitrovarnishes a high degree of strength and good resistance to water, but they can be harmful to human health, as it contains in its composition of toxic solvents.That is why when handling them requires special respiratory protection measures, particularly in respirator.

One of the most environmentally friendly and safe acrylic composition is water-based.It does not burn, provides high strength and elasticity of the coating, perfectly preserves the texture and natural color of wood surface.The coating is transparent and the lack of an ugly yellow color, may have varying degrees of brightness.However, the drying time of acrylic lacquer is directly dependent on the room climate in which it is used.Moreover, experts say that in order to complete the formation of high-quality protective film will need to wait 10 to 14 days!It is not recommended to use acrylic water-based composition on in the rooms with high traffic or high humidity.

are fast drying and epoxy paints, because their drying time is typically less than 12 hours.They are well suited for outdoor work, as resistant to moisture, mechanical damage and chemical attack.Widespread popularity gained polyurethane lacquers, characterized by high durability, resistance to moisture and abrasion.These properties allow the use of this type of composition almost any wooden surfaces.Ideal for protecting parquet, focusing on its aesthetics.Thus, competent selection of varnish for wood - is the key to its beauty, durability and practicality.
