Wooden facades: painting and finishing of facade of a wooden country house

Uncoloured wooden facades quickly darken and become mossy which influences not only durability of construction, but also its appearance. Painting of wooden facade allows protection of wood from not only atmospheric impact, but also from insects.

Preparation of facade surface to painting

Painting of wooden facade is performed only in case if the air temperature is rather high, and its relative humidity is less than 80%.

At first facade surface is cleaned from dust and web. After that the surface is primed and covered with antiseptic prime mixtures. Then one can start painting of facade with paint and lacquer materials.

Slection of paint-and-lacquer material

When choosing paints for facade of a wooden house, first of all pay attention to their capacity to resist to atmospheric changes which can sufficiently reduce life time of coating. It’s not a secret that capacity of paint-and-lacquer material to remain resistant to sun exposure, fluctuations of temperature, and humidity is one of the most important factors of coating durability. That is why it is very important to make the right choice among wide variety of paint-and-lacquer materials, in order to make a wooden facade of your house look pleasant to eyes for a long time!

Oil paints

Oil paints are the most wide-spread type of paint-and-lacquer materials, where different oils (corn, linseed, soybean, hempseed) act as a binding agent.

But hardness and shine of coating of a wooden facade with oil paint are not enough to satisfy demands of modern construction. That’s why oil paints are rarely used in modern decoration.

Alkyd paints

Alkyd paints are produced through synthesis of vegetable oils with alcohols, ahydrites and organic acids. By changing concentration of components it is possible to change properties of general solution. Thus, for example, the more concentration of oil is, the more elastic lacquer coating is, and the more time is required for its drying out.

In any case alkyd paints dry out quicker than oil paints, and their film is much harder.

Aqueous emulsions

Aqueous emulsions are made of the basis of polyvinyl acetate or acrylic and other binding agents on aqueous basis. Properties of aqueous emulsion change depending on binding agent.

Advantages of aqueous paints are obvious. They create coating, elasticity of which in 1.5-2 times exceeds elasticity of coating made of alkyd lacquers, and level of protection of wood from fungi or mould often exceeds traditional coatings.

Reactive paint-and-lacquer materials

Reactive paint-and-lacquer materials create a film in the result of chemical reaction between basic components (resin and hardener) which have limited vital capacity after being mixed in certain proportions.

As a rule, reactive paint-and-lacquer materials have good physical characteristics, they are resistat to impact of chemical compounds and have perfect adhesion with most construction bases.

Polyurethane materials

Polyurethane materials are usually used in industrial construction, as the process of their putting and drying requires special conditions.

Polyurethane paint-and-lacquer materials have the highest weather resistance, increased hardness and good coat elasticity.
